Newsletter articles

By Sue Biondi - December 2020

This article is to inform members and the public about the Lake Anna Dam.  At times of flooding and at times of drought, many wonder why Dominion Power is not adjusting the water level according to the event.  Well, it’s not how the dam functions.  There are many factors that go into how the dam functions and this article will hopefully help answer your questions.

• The Lake Anna Dam is 5,200 feet long 
  
• The structure is 95 feet high
  
• It is powered by one electric diesel generator
  
• There are 3 radial gates and 2 skimmer gates 
  
• The Crest is 265 feet at mean sea level (msl)
  
• Normal lake level is 250 feet
  
• There is a daily operations inspection by Civil Engineers
  
• Monitoring is done with instruments
  
• There is periodic testing
  
• There are annual dam surveys
  
• There is a separate Emergency Action Plan (EAP)
  

Causes of Dam Failures

• Lake Level over topping the dam
  
• Probable maximum flooding (PMF)
  
• Gates failing to open resulting in no discharge
  
• Spillway failure due to PMF
  
• Failure of downstream slope due to earthquake
  
• Failure of spillway due to earthquake
  
• Failure of embankment due to internal erosion (piping)
  

• Potential for human casualties
• Property damage
• Civil penalties
• Financial cost of dam repairs
• Loss of power generation facilities supported by the lake

Impact of a Lake Anna Dam Failure

• Shutdown of both nuclear units for approximately three plus (3+) years. (Time to repair the dam plus the original estimate of 2+ years to fill the lake with normal precipitation)
• Operation of more expensive power facilities to meet demand or power purchase
• Regional business impact:  business revenue; jobs; tax revenue
• Reduced property values
• Loss of a major recreation area for the Commonwealth
• Potential loss of life downstream
• Flooding and resulting damage to downstream roads and properties
• Cost of downstream property damage
• Jeopardize river water withdraw capabilities for downstream businesses and counties

When are these emergency levels entered?

• Imminent and Potential - If the lake level reaches 262 feet, then Potential Failure is declared.  If the water level reaches 265 feet or water is flowing over the dam, then Imminent Failure is declared
• High Flow - When two radial gates get to 4 feet open, the EAP will be entered, notifications will be made and the Lake Anna Advisory Team will be notified.  At 8 feet on two radial gates, the Lake Anna Advisory Team will be activated.
• Non-Failure - Non-Failure is appropriate for an event at the dam that will not, by itself, lead to a failure, but requires investigation and notification of internal and/or external personnel.  This will be identified and taken care of by performing a “Main Dam Daily Inspection,” but EAP notifications are not performed.  

North Anna Dam Safety Program

• The Project is an integral part of the North Anna Power Station
• This Program defines for Federal Energy Regulatory Commission (FERC), Dominion’s commitment to ensure that the Project is operated in a manner that protects public safety, is operated in a manner that does not compromise dam safety or integrity, and inspection programs are in place and properly managed
• Aspects of the Project’s operation, maintenance, inspection, safety and emergency actions are governed in the same manner as programs required by the Nuclear Regulatory Commission (NRC) for the nuclear power station

Chief Dam Safety Engineer

• Responsible for oversight of the North Anna Dam Safety Program to ensure it is fully implemented
• Notifications to Site VP and Engineering Directors
• Routinely assess the organization's compliance with written dam safety program and report the findings to senior management
• Review audit report by Independent Consultant and prepare a summary for senior management

Summary

• The Lake Anna Dam is vitally important to NAPS, Dominion and local communities
• NAPS complies with the FERC rules and regulations
• The NRC believes downstream dam failures warrant an evaluation by the Generic Issues Program
• The economic impact of a Lake Anna Dam failure would be staggering
• The North Anna Dam Safety Program ensures we operate and maintain the dam to protect the health and safety of the public, the company and its customers.

Lake Anna DamAs you can see, when we are all out on a sunny afternoon in the summer enjoying all the recreational activities the lake has to offer, there is so much going on behind the scenes to ensure the safety and integrity of the dam.  If you drive by the power plant and see all the buildings and the two round reactors, take a minute to reflect on the purpose of the dam, the lake that you are enjoying, and saying a special thank you to all the people who make it what it is, that is your Lake Anna!

By Maureen Daniels - December 2020

Be sure to add water temperature to the things you should consider before heading out. You likely know what the air temperature is. Any idea what the water temperature is?  As I write this, the temp on Lake Anna is 53 degrees Fahrenheit.

So how could that affect you at this time of year on the water? 

According to the U.S. Coast Guard, a sudden immersion into cold water, even on a warmish, sunny day, can bring on hypothermia in as little as 3-5 minutes.

Cold water sucks heat from the body, and the body’s core temperature drops. This can lead to loss of consciousness and, ultimately, death. Hypothermia happens very quickly.

What are the first symptoms of cold water shock?

Initial “cold shock” occurs in the first 3-5 minutes of immersion in cold water.  Sudden immersion into cold water can cause immediate, involuntary gasping; hyperventilation; panic; and vertigo—all of which can result in water inhalation and drowning.

All of us know what various air temperatures feel like so we dress accordingly.  Many of us know how chilling that first dip into the Lake in May can feel.  Jump in, gasp!  Lips might turn blue.  Get out, shiver.  That is a mild case of hypothermia.  Imagine being immersed in that cold water for any length of time.  Most of us have never experienced being in extremely cold water, so it is hard to imagine the consequences.

Normal body temperature is about 98.6F.  Treat any water temperature below 70F with caution.  Swimming in temperatures below 70 degrees can lead to increased heart rate and blood pressure, which can put you at risk.  

Prepare for the unexpected.

In the fall and winter, you likely are not planning to be in the water.  However, capsizing, swamping, and falling overboard are leading causes of cold water immersion—not planned events.

If you end up in the water, do you have a way to get back onto your boat, board, kayak or canoe?

What you can do to be safe and enjoy your time on the water

1.    Wear a Coast Guard approved life jacket. It will not do you any good if you end up in the cold water and your life jacket is on the boat or paddle craft. A life jacket will increase your chances of surviving cold water immersion.

2.    Be sure whatever vessel you are using is in good shape—gassed up, charged battery, drain plug installed, appropriate paddles.

3.    In paddle craft especially, keep a low center of gravity, distribute weight evenly.

4.    Let someone know that you are out on the water, where you expect to go, and when you plan to come off the water.

What you should do if you do end up in cold water . . 

Try not to panic.

Get your breathing under control

Leave layers of clothing on to help prevent body heat loss

If possible, stay with the vessel and get as much of your body out of the water as possible.

Remember— your life jacket will help support you.

Lastly, seek medical help as soon as possible, as post-immersion collapse can happen during or after a rescue.  A drop in blood pressure can lead to cardiac arrest.

On thin ice . . .When in doubt, don’t go out!  While some parts of the Lake may look like they are completely frozen over, do not take any chances.  Ice freezes and thaws at different rates and ice thickness can vary depending on currents, springs, depth and debris in the water.

This is another circumstance that puts you at high risk for hypothermia if you were to fall through the ice.

Don’t forget . . .Protect your pets!  They can be susceptible to the same health issues and life threatening circumstances when in cold water.  If it is too cold for you to be in the water, it could be too cold for them, as well.  If you are not comfortable going out on the ice, don’t let your pets venture out either.

Be safe!

Avoid Spot and Treat Frostbite & Hypothermia

By Greg Baker - December 2020

As I sit down to put pen to paper or, more accurately, fingers to keyboard, it has been a strange and melancholy year here at Lake Anna. We are all still in the midst of the pandemic with over 300,000 cases in Virginia and a little more than 4600 deaths. Most of us probably know someone diagnosed with the disease and worse, know of someone that has sadly passed away. But in some ways, and maybe it is a false sense of security, Lake Anna seems to have been relatively spared. I can’t easily find the specific statistics for just the lake, but the combination of Louisa and Spotsylvania County has had 4718 cases and 71 deaths as of this writing according to the Virginia Department of Health website. And of course, these numbers are skewed dramatically by the city of Fredericksburg in the Spotsylvania numbers, meaning the exposure here at Lake Anna is likely far, far lower. If you are so inclined to follow the data you can do so by clicking the map below. It also allows for you to drill down to our surrounding counties.

Because of shutdowns and the concerns around traveling or flying, families have been looking for options to do "staycations" closer to home and many new visitors have discovered all the wonderful options that are available here at Lake Anna. 2020 seems to have been the busiest year that I can remember in my 30 years of owning property at Lake Anna. Many or our members may not like our “secret” getting out, but we are blessed to have access to such a beautiful place to hunker down and get through the pandemic. I certainly do not mind sharing our oasis in central Virginia with our friends and families.

The pandemic has had its impact on our work at LACA. First, we stopped our in-person monthly board meetings in March. We did not miss a beat with access to Zoom and we adapted very quickly to virtual board meetings. (Although we all at times struggle with our lack of speedy internet access here in the country!) Not sure that I can speak for the board, but I actually prefer the virtual meetings. We will see if we ever go back to traditional in-person meetings or not. This allows for our non-resident volunteers to join our meetings year round and allows for all of our members to sit in on our meetings as well. Our board meetings are always open to the public and are held at 5:00PM on the first Thursday of each month. Please drop in if you are interested in the interworkings of our board. We try and post the Zoom credentials on our website a day or two before the meetings or you can always email me at greg.baker@lakeannavirginia.org if you are interested in attending.

We also had to cancel our in-person annual meeting in July. We were determined to host the meeting and ultimately, we conducted our first ever Zoom annual meeting in late October. It went off beautifully and was well attended. Special thanks to Dr. Jennifer Graham who gave a very interesting presentation on Harmful Algae Blooms (HABs).  It was a long meeting, but you can actually view the meeting recording on YouTube by clicking the photo below and fast forwarding to the parts that interest you. I would highly recommend watching Dr. Graham’s presentation.

The pandemic also curtailed our water quality efforts as well as those conducted by DEQ. LACA had to postpone or cancel some of our testing in the spring.  As the summer progressed and the pandemic threat level subsided, our volunteers were able to adapt and get the work done on your behalf. While I am on the subject of water quality, I wanted to highlight just a few of the efforts of our water quality folks that were led by our co-chairs, Harry Looney and Mike Gelber. I am continually impressed by their dedication to keeping Lake Anna’s water clean and ultimately solve what has become our ongoing battle with HABs.

One of LACA’s most important accomplishments was to develop, with the help of DEQ, VDH, Soil & Water Conservation Districts, USGS, local universities and others, a HAB Recovery plan. A significant amount of work went into this plan.  It is a living, breathing document that will help guide LACA in our efforts to fight and win this battle. LACA has participated in many, many meetings with all of our stakeholders.  You can see a list of LACA’s accomplishments ,that we published for our annual meeting, which includes the work of our water quality committee but also the work done by the Land Use, Environmental Preservation and our Emergency Services & Safety Committees.

LACA expanded its traditional water quality monitoring program by adding weekly testing for algae and toxins on the lake. Next year the water quality team is working with academia and The National Oceanic and Atmospheric Administration to try to incorporate satellites to identify HAB “hot spots” on the lake to fine tune our testing and better deploy our resources of volunteer time and the costs of the lab work. This is fascinating stuff, using computers and satellites to help identify possible HAB outbreaks by analyzing pixels on maps that represent 10-meter square sections of the lake. This is truly amazing! NOAA established a website to show the actual images that will be used. You can click on the following map to see the images yourself.

Harry Looney will be writing a year-in-review on the water quality program in our next newsletter, so I will keep you in suspense for all that has happened in 2020 and what to expect further in 2021. We can always use volunteers to help collect water samples and also to help in data analysis and other projects related to water quality. If you are interested in volunteering for these efforts, please reach out to Harry at harry.looney@lakeannavirginia.org.

I am also very proud of our membership’s support of our call for donations to co-invest with the Lake Anna Advisory Committee on phase one of a robust watershed study to understand the causes and potential remediation of HABs. We agreed to fund $10,000 towards this study and raised nearly that amount from your generous donations. The first phase of the study will focus on the North Anna branch of the lake and phase two will focus on the Pamunkey Creek and Terry’s Run section of the lake. The study is well under way and I will report back to our membership as I hear of their findings. If you missed the opportunity to donate to this very worthy effort, please consider making a tax-deductible donation to our water quality programs. 

Speaking of finances, LACA operates on a shoestring budget and much of what we are able to accomplish is funded by grants or your generous donations. Clearly, we are not able to execute our goals based on our very low $15 annual dues. Therefore, there are a couple of announcements that I would like to make.

First, in order to continue to represent our growing community and to execute our mission, we need your help. We hope to grow our membership in the new year.  We will be announcing a March to 1000 Membership Drive with some great prizes for those of you that help refer members to LACA. While the membership drive has not started officially, any members you refer that add your name in the referral field on the membership application form, will count towards upcoming contests. Please be on the lookout for our announcement early next year. In the interim, please consider telling your friends and neighbors about all that we do and encourage them to be part of our journey! New members can easily join on our website by clicking here. 

Secondly, we are discovering opportunities to apply for grants that could help LACA execute our vision. We felt the need to have a "go to" person to spearhead our grant writing effort. Since none of your board is qualified to do so, we are going to try and learn on the job.  We have asked Jack Molenkamp, who kindly volunteered to help LACA, to act as our grant writer. While Jack admits that he does not have any experience in grant writing, we are undeterred and very happy to have Jack help us in this effort. If you are experienced in this field and are willing to help or provide advice, please consider contacting us! It will be very much appreciated.

Speaking of grants, LACA is proud to announce that we received an $8,000 grant from the Dominion Energy Charitable Foundation. Thanks to Mike Gelber for leading this effort. The grant is for a program that LACA and Mike will develop in the spring to deploy floating wetlands at Lake Anna. Floating wetlands are small islands that float on the surface and are planted with native species. The plants’ roots grow through the island and dangle up to 2 feet below the surface. These islands are very effective in competing for nutrients, which could help starve HABs. We hope to work with the Louisa County High School students in the late spring to install several of these islands in the lake. Mike will be writing an article with more details in a future newsletter. If you are interested in helping with this project, please reach out directly to Mike at mike.gelber@lakeannavirginia.org.

LACA and your board recently reworked two of our six regions. This was done to more equally divide our membership among our regional directors and to also help to better represent the private side of Lake Anna with our board. The two new regional boundaries are now logically divided to represent members on the public side versus the private side of the lake.One of our long-time regional directors recently stepped down from our board and we currently have an opening for a regional director to represent this newly drawn region on the private side of the lake. This is an opportunity to have a very important impact and we would love to hear from interested volunteers. If you currently are an active member of LACA, live or own a home on the private side and would be interested in being a member of LACA’s board, please email me at greg.baker@lakeannavirginia.org. I will be happy to share with you what to expect as a regional director and what are the regional director responsibilities. Please consider volunteering!

As you can see, even in a pandemic, there is much going on with LACA and I have just scratched the surface of our activities in this column. There is much to do and it has been a privilege serving our community and working with the dedicated volunteers that make up LACA. I wish all of our members a very safe and Happy Christmas and a wonderful and hopefully a very different New Year in 2021!

(By the way, a big THANK YOU to J.D. Edwards our newsletter editor. JD gives fully of himself, not only to help us out at LACA, but he is a big volunteer at the Louisa County Resource Council. The world is a much better place with folks like JD!)

Covid couldn’t stop LACA from holding its annual meeting, even though it had to be postponed briefly and then held virtually on Saturday morning, October 24.  Nearly 150 members and guests logged in to hear what the civic organization has been doing in the past year.

With the third season of swim advisories, due to harmful algal blooms, the board chose Dr. Jennifer Graham, Research Hydrologist with the U.S. Geological Survey as the guest speaker.  Dr. Graham’s topic, “Cyanotoxin Occurrence in the U.S. -- A 20-year Retrospective,” provided an in-depth history of the occurrence of algal blooms and how the evaluation process has changed over the years.  Her presentation is included in the record of our minutes and if you missed the meeting you can access the recording on our website or by clicking here.

We also welcomed our two new board members – Pamela Hahn, the Mineral/Louisa regional director, and Rick Nehrboss, the Brokenburg regional director.  Both were elected in July during online voting, another new process for the association.  President Greg Baker also introduced Jean McCormick, the Cuckoo regional director who was appointed in September following the resignation of Dick Shrum.

One of the key accomplishments for the organization this year is the new website which offers members the ability to maintain their own information and allows the board to send the newsletters via email, resulting in a tremendous savings in the budget.  The website allows for more flexible contact with our members, more up-to-date information as well as the ability to pay membership dues and make donations online.

The biggest focus of LACA this year has been related to the harmful algae blooms and water quality with the Water Quality Committee and Environmental Preservation Committee teaming up to work on potential solutions from different angles.

LACA is also contributing $10,000 to the Lake Anna Advisory Committee’s [LAAC] sediment study which is currently underway.  LAAC is a sister organization comprised of representatives from the three county Supervisors [Louisa, Orange and Spotsylvania] as well as citizen representatives from each county.  They are undertaking a three-phase effort to determine the source of the algae reaching the lake and find ways to mitigate the causes.  The Water Quality and Environmental Protection committees are also closely monitoring the efforts of LAAC

Another feature of the annual meeting is the presentation of the Jack Bertron Distinguished Service Award.  This year, three people were recognized for their contributions to the organization and the Lake Anna community.

Patty Shapiro retired from the board this year after serving for 15 years, first as the association’s secretary from 2006 to 2010 and then as the Brokenburg regional director from 2010 until her retirement. 

Ken Remmers stepped away from leading the Water Quality Committee in 2019 but continued to work with the new leadership in the transition.  Under his leadership the water monitoring program expanded its focus and outreach by partnering with numerous agencies in the state.  He was presented the award for the second time for his many hours of service to protecting Lake Anna.

Steve Falkenthal also received the award for the second time as he retired from his role with the Water Quality Committee.  Steve spent many hours navigating through the water quality data, ensuring the equipment was calibrated and ready to go each testing day and working to ensure the program maintained its Level 3 certification with DEQ.

Both Ken and Steve put in many hours improving the standards used by the water monitoring teams in keeping LACA as one of the few citizen monitoring teams recognized by DEQ as capturing data equivalent to theirs.

President Greg thanked all three honorees for their many years of dedicated service to the volunteer organization, often while still working regular jobs.

Reports from other committees are captured in the recording of the meeting and a synopsis of each committee’s activities can be found on our You Tube channel by clicking here.

If you have friends or neighbors who aren’t members of LACA but are interested in hearing the information presented, please share it with them and encourage them to join.  LACA is an all-volunteer organization so if you would like to get involved, reach out to one of the board members or committee chairs – their contact information is all on the LACA website.

November is a significant month for Lake Anna’s aquatic life and continued good water quality.  It is the time of the year when the lake “turns over”, meaning the internal workings of the lake completely mix the water throughout the entire depth of the lake, sometimes referred to as the water column.  This mixing brings much needed oxygen from the surface water region (scientific term is epilimnion) to the lake’s bottom layer (hypolimnion).  Likewise, the nutrients that have been generated and are present at the lake’s bottom are released throughout the water column.

To understand how and why the lake mixes, one must first understand the relationship between water temperature and its density.  Water possesses a unique property in that it is most dense and therefore the heaviest when its temperature is 39.2 degrees.  Above and below this temperature, water is less dense.  See the below table for the weight of a gallon of water at various temperatures.

In the summer months and in the mid to lower section of the lake where water depth exceeds 40 feet, the lake becomes stratified into three layers where the water temperature within each layer is relatively constant.  See the below table.  In June and for the first 40 feet or so it is not uncommon for the water temperature to be about 81 degrees at the surface and roughly 74 degrees at the 40 foot level.  Another layer (metalimnion), commonly referred to as the thermocline, extends down to a depth of about 60 ft where the temperature at that depth is on the order of 63 degrees.  Below the 60 ft level, water temperature drops to approximately 60 degrees at the deepest part of the lake.

Lake stratification slowly disappears in the mid to upper region of the lake.  At The Splits (North Anna River/Pamunkey Creek) and above, the lake becomes shallower and the water temperature is uniform throughout the water column.

As the season transitions from summer to fall, the surface water becomes increasing cooler.  As it cools, it becomes denser (heavier) thereby, displacing the water at lower depths.  By about mid November, the water temperature at the surface near the dam and at a depth of 69 feet will be about the same, approximately 62 degrees.

Throughout the fall and winter, the water will become colder within the water column; however, the variation in temperature will be minimal. Since there is minimal temperature variation, nutrients and oxygen travel freely within the water column. Wind assists with water circulation. Come late spring, the lake’s surface layer will begin to warm and by the summer, the lake will once again be stratified where oxygen within the highly oxygenated top layer and the nutrients in the nutrient rich bottom layer will remain “trapped” until the lake “turns over” again in November 2021.

The Virginia Conservation Assistance Program (VCAP) is an urban cost-share program that provides financial incentives and technical and educational assistance to property owners installing eligible Best Management Practices (BMPs) in Virginia’s participating Soil and Water Conservation Districts (SWCDs). Most practices are eligible for 75% cost-share and some practices provide a flat incentive payment up to the installation cost. These practices can be installed in areas of your yard where problems like erosion, poor drainage, or poor vegetation occur. Qualified sites shall be used for residential, commercial, or recreational purposes with a proposed practice that addresses a need.

Your Local SWCD Can Help You…

 Restore problem areas
Control and minimize erosion
Conserve water within the landscape
Improve riparian buffer areas
Promote wildlife habitat
Re-vegetate bare slopes
Stabilize drainage ways
Treat stormwater runoff

We Help You Make a Difference…

Why do Virginia’s waters need improving? Nonpoint source pollution is the leading cause of water quality problems. Rainfall or snowmelt from suburban lawns, golf courses, and paved surfaces picks up and carries away natural and human-made pollutants depositing them into lakes, rivers, wetlands, coastal waters and ground waters.

Roads, parking lots, sidewalks, homes, and offices replace natural landscapes. Rainfall that once soaked into vegetated ground now becomes stormwater runoff, which flows directly into local waterways.

As more natural landscapes are converted to impermeable surfaces or managed turf, stormwater moves across them, carrying pollutants such as sediment and nutrients to vulnerable streams and rivers. Storm drains you see on the street do not provide any sort of water filtration.

Virginia’s Watershed Implementation Plan (WIP) for the Chesapeake Bay identifies that urban/suburban runoff is contributing to impairment and efforts to retro-actively address stormwater runoff from existing impervious surfaces is a priority. VCAP is an opportunity to help you do your part to improve water quality.

As part of our ongoing efforts to prevent Harmful Algae Blooms (HABs) from forming on Lake Anna, LACA established an academic partnership with the Environmental Studies Program at Randolph-Macon College (R-MC) in early 2020, initiating a research effort to sample, measure and analyze nutrients (phosphorous, orthophosphates and nitrogen) in the lake sediment.  Dr. Mike Fenster and Dr. Chas Gowan lead the R-MC research program that will involve sediment sampling in the lake north of the 208 bridge. 

The R-MC research program began in August when the students returned to campus and started the fall semester.  R-MC’s fall semester is broken into two parts due to COVID-19 restrictions and school protocols.  The Environmental Studies course was only 8 weeks in duration, so the faculty and students had to fit a considerable amount of planning and preparation into a short period of time. 

The R-MC research program is focused on sediment collection in the main tributaries from the 208 bridge to the northern headwaters of the lake (North Anna River, Pamunkey Creek and Terry’s Run).  We included several creeks in the upper lake area as well (Plentiful Creek, Foremost Run and Ware’s Creek).  The R-MC research program will be conducted over several academic semesters.  All data will be analyzed by the students to quantify the levels of nitrogen, orthophosphates, and phosphorus in the sediment.  We expect to have initial insights after completion of program activities in the spring semester (April 2021).  All data, insights and results generated by the R-MC research will be provided to LACA for our internal review.  The R-MC research in the spring semester will focus on data analysis and visualization to inform our understanding of how the nutrients in the sediment can be made available to cyanobacteria that are naturally present in the lake.

The R-MC fall semester execution plan was impacted significantly by COVID-19, so the students were not able to go out on the lake to collect samples.  LACA and the Virginia Department of Environmental Quality (DEQ) implemented a back-up plan and were able to collect samples at nine locations.  The data generated by this sampling effort will be used in the continuing R-MC research effort.  LACA thanks the R-MC faculty and students for their efforts under such unfavorable, extreme conditions. LACA also thanks DEQ for their efforts in stepping in to collect the sediment samples when COVID-19 impacted the R-MC sampling plan.

Results from the R-MC research project will be shared with the Lake Anna Advisory Committee (LAAC) that is executing a comprehensive study to determine the cause of our recent harmful algae blooms (HABs) and to inform course-of-action development into potential remediation actions that could be taken.  Phase one of the LAAC project focuses on the North Anna River from Holladay Bridge west to the upper reaches of the lake.  The objective of LAAC’s robust study is to determine the magnitude of phosphorus and nitrogen loading from external (from the streams) and internal (in the water column and sediment) sources.  The tasks that will be executed to achieve their objective include mapping the North Anna River watershed, mapping of the lake bottom and sediment sampling.

Sediment nutrient loading is one of the key knowledge gaps that LACA, LAAC and DEQ have identified with our understanding of the lake dynamics.  Both the R-MC academic research effort and the LAAC project are working to fill this knowledge gap so our decisions are based on data and science informed by relevant, current data. 

Interested LACA members are welcome to volunteer in support of this research program.  Contact the Water Quality Committee leads if you are interested in learning more or volunteering to support this research program.

 Thank You to:

•  The majority who operate boats and jet skis responsibly and are mindful of how their favorite activity might be affecting others enjoying theirs!

•   The members of the Lake Anna Rescue Group (LARG): Louisa and Spotsylvania deputies; Police officers from the Department of Wildlife Resources, formerly known as DGIF; Louisa and Spotsylvania Counties’ Fire & Rescue personnel; particularly, the Spotsylvania Dive Team, all of whom ran patrols on the Lake on weekends and holidays. They provided a consistent presence on the water and were able to respond to incidents in a more timely manner.

Members of LARG participate in two drills each year. The goal is to to improve communication, cooperation and coordination of assets and personnel from all the agencies who respond to emergencies on Lake Anna.

•   To all members of the Lake Anna community who have installed yellow and black 911 signs on their docks and in common areas. All incidents on the water are dispatched to the exact dock sign—or nearest sign—which serve as water based 911 addresses for law enforcement and fire & rescue. In some cases, since they are linked to the 911 street address, responses were made by road and water. Get your application on the LACA website.

•   To our safety partner, Dominion Energy, for funding the installation of yellow and black 911 signs on their islands, which serve the same purpose as 911 dock signs.

•   To the Lake residents who have successfully advocated for Louisa County funding, and have established a fund raising campaign to make the New Bridge EMS Station a reality. The Rescue Station will serve the Lake Anna community and residents and visitors who experience an emergency on the Lake.

Make It Happen Lake Anna!

The Foundation for Lake Anna Emergency Services for the New Bridge Rescue EMS Station is very close to reaching their goal of raising $100,000. Your contribution now can put them over the top!

This article is a reprint of an article that was first published in October 2018. It is a seasonal reminder that blowing leaves into the lake is not a good practice, especially given the recurrence of Harmful Algae Blooms over the past three years.  

As homeowners, it is difficult for us to control the amount of nutrients that enter our lake from upstream sources; however, as residents we can control what enters the lake from our respective properties.

Blowing leaves into the lake is not recommended.  Although not illegal, it is a form of littering that is discourteous to neighbors and it is harmful to the lake’s ecosystem.

Leaves blown into the lake rarely settle at the shoreline of origin.  They are carried by wind and current to other locations before they reach bottom.  In coves, it is usually the few lots at the back of the cove that receive the leaf debris.  They are unsightly and over time, sedimentation buildup will cause these owners to lose water depth and will leave them with a squishy bottom.

Decaying leaves release nutrients, primarily carbon, nitrogen and phosphorous.  These nutrients are great for soil but excess nutrients are a pollutant to lakes like ours.  These nutrients, especially phosphorous, are a fertilizer for hydrilla and algae, promoting their growth.  As hydrilla growth spreads, herbicides and/or carp are then needed to control its growth. 

Similarly, excessive nutrient levels can contribute to low dissolved oxygen levels by causing abundant growths of phytoplankton (microscopic plants and algae) called blooms. Living phytoplankton may deplete oxygen levels during the night and as the phytoplankton die; decomposition of the organic material by bacteria consumes oxygen.

Let’s all be good neighbors and good stewards of our lake’s ecosystem by not blowing leaves into the lake.  Instead, consider collecting and finely mulching them and spreading them so their nutrients can be returned to your soil.

Orange County Resort Update

LACA alerted our membership to the Special Use Permit (SUP) application for the Orange County Resort by both an E-Gram, on our website’s home page and under the land use program section of the website. 

The Orange County Planning Commission (OCPC) heard the application at their regular meeting on August 20^th, 2020. The OCPC voted to deny the application by a unanimous vote of 5-0. 

The original application was ultimately amended and called for daily rentals of 150-175 luxury motorcoaches along with amenities such as fuel sales, a camp store, a marina and up to 150 docks.

LACA had many concerns related to this development that it shared with the OCPC and with our membership. In an “E-Gram: Call to Action” alert to our Region 7 membership, we pointed our members to our list of concerns on our website and urged members to write emails of concerns to the OCPC. This effort led to approximately 80 emails to the commission, of which the majority were from LACA members. 

The commissioners took note of these concerns and referenced the issues in their comments to the developer. Some of the highlights from the meeting were as follows:

• One member stated that in his 8 years on the commission, that the application was the worst he had ever seen.
• Several members said the development would be a non-starter without turn lanes off of route 522.
• The members acknowledge the many concerns brought up by citizens including those shared by the Lake Anna Civic Association.
• Gary Griffith, the developer’s representative, requested that the SUP be tabled to allow for the developers to address more of the concerns. However, the chair stated that this option was provided prior to the meeting and that Mr. Griffith had insisted on being heard at the August 20^th meeting. 

This development straddles the Orange County and Spotsylvania County line. As of this writing, the SUP for Spotsylvania County has not been scheduled to be heard. 

Ultimately, LACA believes that the developer will rework their proposal and resubmit a revised plan. We hope that our recommendations will be incorporated into any revisions. We will continue to monitor this development and will keep our membership abreast of any pending meetings or opportunities for feedback.

LAAC Phase One HAB Study Approved

The Lake Anna Advisory Committee, different from LACA, is a quasi-governmental organization established collectively by the three counties surrounding Lake Anna. LAAC is best known for maintaining and approving various regulatory buoys on the lake as well as controlling hydrilla among many other things. Their primary focus is to coordinate lake concerns with Louisa, Spotsylvania and Orange Counties. 

LAAC’s Board had the vision to create a three-phase program to understand and ultimately address the Harmful Algae Blooms (HABs) that the lake has suffered through the past three years. Phase 1 is a comprehensive study of the watershed to determine the cause and potential remediation of HABs. Phase one would focus on the North Anna Branch from the upper reaches of the lake to the Holladay Bridge. 

The study is robust and includes determining the magnitude of phosphorus and nitrogen loading; both internal and external. It would include mapping of the watershed, mapping of the lake bottom and sediment sampling to determine the existing nutrient loads that have developed over the lake’s 50-year life. You can learn more by reading the Request for Proposal.

Phase 2 of the study would expand on Phase 1 and cover from the Holladay Bridge down to the “splits” (in front of the state park) and back up the lake to include all of the Pamunkey Creek and Terry’s Run sections of the lake. Phase 3 would be the remediation phase to correct the issues that are discovered in Phases 1 & 2.

The cost of Phase 1 will be approximately $50,000. I am happy to announce that the LACA Board voted unanimously to contribute $10,000 towards the cost of this very important first step. Phase 2 will be substantially more expensive and Phase 3 will likely need to be funded by the Virginia General Assembly. 

LACA New Board Member Approved

Dick Shrum, the newly reelected Regional Director for region 2, the Cuckoo District tendered his resignation to LACA shortly after the recent LACA elections this summer. Dick has served on the LACA board for many years and we will miss his dedication and the knowledge of the private side that he brought to our board. Dick continues to serve as the treasurer of LAAC. He will be missed.

The board nominated and approved Jean McCormick as his replacement. Jean’s volunteerism on Lake Anna is well known. She is a member of the US Coast Guard Auxiliary and serves as the Chair of LAAC’s Navigation Committee. We are lucky to have Jean representing region 2 and we appreciate her willingness to serve.

Annual Meeting Update

With no end in sight to the coronavirus pandemic, LACA’s board made the decision to postpone our regularly scheduled in-person annual meeting in July. We had hoped to reschedule an in-person meeting later in the year, but the board believes that the best course of action is to host the meeting virtually. The meeting is tentatively scheduled for October 24^th and will be hosted using the Zoom platform. More information will be coming in the next few weeks as we coordinate a guest speaker and finalize our agenda. We will post information on our website and send an E-Gram once the plans have been finalized.
