FBL winter newsletter 2021
Dear Friends and Neighbors,
The Friends of Bolton Lakes welcomes in a new year with the firm hope that the pandemic will be behind us and we can begin to enjoy a bit of normalcy in and around our wonderful lake region.
FBL achieved many of the goals we set last year in spite of the difficulties presented by the pandemic. We have continued our joint work with the towns of Bolton and Vernon moving closer to watershed management rather than individual lake management. In early spring of 2020, the Middle Lake had an algae bloom that sickened a dog but dissipated rapidly. In addition, the Middle Lake had a small fanwort patch that was treated late in the summer. The Lower Lake had a curly pondweed outbreak that was treated. Overall, it was a good year for lake clarity and lake health.
Here are some relevant things to look for in 2021.
The Bolton Lakes Region Watershed Plan is well on its way to completion.
• DEEP (Department of Energy and Environment Protection) approved the request to use the remaining funds from the STEAP (Small Town Economic Assistance Program) Grant to allow the watershed plan to be initiated.
• Many of our members responded to a recent watershed survey. We thank you. The current views of our lake stakeholders will be compared with the future views from a second survey.
• A forum will be organized in the spring for receiving public comment and to discuss the plan’s implementation projects. Funding to complete the watershed plan will come from town resources. More to come.
The State’s Office of Policy and Management, Budget & Financial Management Division has approved funding for the Hatch Hill culvert [dam] renovation. The design was previously accepted by the DEEP Division of Dams and Dam Safety in 2018. The request for proposal is in process and expected to be finalized this spring. Construction is targeted for fall 2021 immediately following the fall drawdown.
At its first meeting last February the stakeholders of the Bolton Lakes Watershed included FBL, the towns of Vernon and Bolton, DEEP, and consultants from NEAR (Northeast Aquatic Research). Together they established short- and long-term goals to develop an effectively managed drawdown program, developed a set of protocols for maintaining the seasonal water levels of the lakes and created a procedure that could mitigate the known uptick of invasive plants and other non-native species that are infiltrating the lakes. The meetings will continue and will be part of the watershed management plan.
The equipment that detects Cyanobacteria in the lakes purchased with a Connecticut Federation of Lakes grant is being used to contribute to the national BloomWatch project collecting data on cyanobacteria. Additionally, two lake level monitors were purchased with funds from the STEAP grant. One logger was placed on the Lower Lake, the other on the Middle Lake and they have been monitoring the lake levels every hour since November. We are still working with DEEP to obtain data on the sluice gate valves to understand how they are opened and closed to regulate the level of the lakes. That data should allow us to keep lake levels more constant during the drawdown periods.
A virtual Spring Seminar is being organized to present the results of the CAES (Connecticut Agricultural Experiment Station) invasive plant species survey of the Middle Lake which was completed in 2020. Invasives such as fanwort and milfoil continue be on FBL’s radar. We are attempting to have signs erected at the boat launches and have a boat launch ambassador program to alert lake visitors of the dangers of invasive plants. FBL will continue to monitor and test the water quality and clarity in the Bolton Lakes and share the findings with the towns and NEAR. The data is vital to the implementation of the watershed plan. This year we hope to make some of that data (clarity and temperature) available on our website.
We were pleased to have had members join the monthly meetings and bring their valuable insights. I urge and challenge everyone to stay involved with FBL and attend at least one monthly virtual meeting during 2021. It’s easy. Just send an email to fbl@friendsofboltonlakes.org to request the ZOOM link. The meetings are held at 6:30 PM on the third Wednesday of each month.

Fall lake Drawdown
On Tuesday, October 13, 2020, Bolton and Vernon town officials hosted a Zoom meeting. The towns’ limnological consultant NEAR (Northeast Aquatic Research), FBL board members, DEEP (Department of Energy and Environmental Protection) personnel, and other representatives participated in the meeting. During the meeting, DEEP reported that the annual drawdown of the Bolton Lakes will begin on or about November 1st and will be 18 inches as it has been for the last few years.
The 18-inch reduction is from the normal surface level. To date, both lakes' water levels are already several inches below normal levels so an 18-inch drawdown should be accomplished quickly.
This year NEAR, in partnership with FBL, will monitor the level of the lakes and receive drawdown data from DEEP. The data that is collected will aid in developing operational protocols for future drawdowns of the lakes. As always, the reduction rate will depend on the weather and other factors.

Fanwort treated - watch for and report sightings
September 2020
Recently, a small patch of fanwort and a larger patch of milfoil were treated on the southwest side of Middle Bolton Lake. That treatment appears successful. This weekend four strands of fanwort were found near the boat launch on Hatch Hill. On advice from the lake limnologist, we are asking everyone on the lake for two things. First, if you see some plant you don't know or you do know but know it should not be in the lake, use the FBL "Report a Suspicious Plant" menu item.
Second, avoid fishing in the area right in front of the boat launch and ask others to avoid fishing there too. Fanwort spreads through fragmentation which can be caused by fishing. Treating invasive species works through vigilance and identifying issues before they become big problems. Your help is essential. We've included a picture of fanwort below.
Thank you,

Fanwort treatment on mbl and more
August 2020
As summer draws to a close we have some information to share with you about our lakes.
Curly Pondweed on Lower Bolton Lake
The curly pondweed on Lower Bolton Lake was treated in July and the treatment seems to have worked. Currently there are no plans for additional treatment.
Fanwort and Milfoil on Middle Bolton Lake
At the beginning of July a member of FBL submitted a sighting of fanwort to the FBL invasive plant reporting tool. Later in July, the Connecticut Agricultural Experiment Station, contracted by FBL, conducted a Middle Bolton Lakes Plant Survey. As a result a small patch of fanwort and a slightly larger patch of milfoil was identified near the shore on the southwest side of the lake. The survey findings were then verified by the Northeast Aquatic Research limnologist. Subsequently, the town of Vernon funded a chemical treatment to be administered by Solitude. The treatment chemicals will combat both milfoil and fanwort. It will be done this Thursday, August 27, 2020 (changed from Tuesday, August 25). Relying on protocols from 2019 with similar treatments there will be minimal, if any, restrictions on lake use either by swimming or watercraft.
Koigate on Middle Bolton Lake
In April a large orange and white koi [carp-like fish] was spotted in Middle Lake near the boat launch. In May, two were spotted together on the southeast side of the lake in shallow water. Although it is an illegal act to use the lakes for disposal the initial feedback from the authorities was ‘not to worry’ until they had a chance to complete their research and convey their findings to FBL. See the picture below.
Since then the fish have been spotted several times in various places around the lake. Jeff Phelon, a FBL member, also contacted the DEEP (Department of Energy and Environmental Protection) Fisheries Division on his own out of concern that the koi might be invasive. Chris McDowell, from the DEEP Fisheries Division, responded with the following information: “Dumping Koi or any other fish in the lake is illegal. But the koi are harmless to the environs of the lakes and DEEP has no record of a sustained population of koi or goldfish in a Connecticut lake. Therefore, DEEP is not going to take any action to eradicate the fish. That said, if the eagles do not take advantage of an easy prey, feel free to take them out of the lake.” Similar to most carp, they will bite on a hook hidden in a ball of bread. If you do catch the koi or find their bodies, please take good pictures and send them to FBL at fbl@friendsofboltonlakes.org. We will forward them to DEEP so that they can document having them in the lake.

welcome to summer on the lakes
June 2020
Dear Friends and Neighbors,
We trust that you and your families are staying healthy and safe.
Summer is here! The water temperature is over 77 degrees and heading up.
We want to bring you up to date on several items of interest to the Bolton Lakes community.
Spring Seminar
Due to the continuing Covid-19 crisis we did not have a spring seminar. We hope that by the fall we will be able to have our usual meeting. We will let you know as the date gets closer.
Cyanobacteria Bloom This May
This spring (starting around May 19th) the lakes had an unusually high amount of visible algae, including significant cyanobacteria. Several submissions came in through the FBL Invasive Plant Reporting Tool (https://www.friendsofboltonlakes.org/report-a-suspicious-plant.html) reporting cyanobacteria blooms on both lakes. Some cyanobacteria can produce toxins that are harmful to pets and people. Last year FBL got a grant from the Connecticut Federation of Lakes to purchase a Cyanoscope testing kit. This spring Paul Weisser used the microscope and software to determine that the cyanobacteria in our lakes is primarily Dolichospermum. These cyanobacteria do produce harmful toxins. Other algae tests that FBL conducted showed the presence of Chlorella and Chlamydomonas; these are non-toxic green algae.
A dog playing in Middle Bolton Lake became sick and, after a blood test by a local vet, it was determined the dog had microcystin toxins, the toxin produced by cyanobacteria. The dog has recovered at home. The owner contacted the DEEP (Department of Energy and Environmental Protection) and the district health department. The water was tested, and the level of cyanobacteria was below the level that the state uses to determine if public advisory signs are needed. But, out of an abundance of caution, the state did post signs warning that people should be aware that there are cyanobacteria in the water, and they should not swim in ugly water. After the posting of the signs, the water was tested over a two-week period and each time the level of cyanobacteria was significantly below the level that is considered harmful. The signs were taken down.
The bottom line is that cyanobacteria are always in the lake. In the spring there is a combination of an increase in nutrients through over fertilizing, pollen and runoff from spring rains; the heating of the lake water causing a uniform water temperature distribution; high winds that cause the water in the lake to mix; and warmer weather. These create good conditions for bacteria to grow and when they grow exponentially there is a bloom. Don’t swim or let your pets play in water that looks green.
Since this algae problem has subsided both lakes have shown a remarkable increase in clarity. Secchi depth (the deeper the clearer) has been in the 4-meter range on the lower lake and 3.5 meters on the middle lake. Several residents have reported easily seeing both bluegills and bass forming spawning pools in the shallows off their docks. The channel catfish are still around, but our older fish populations may be making a comeback. While we enjoy the clear water, we must remember that aquatic plants respond to the increased light and will grow well. These plants produce oxygen, which is essential for the lake, but we must remain vigilant for the invasive species that clog the water and force out the good plants. Of high concern among these problem plants is curly leaf pondweed with its lasagna noodle leaves. Please keep an eye out for this one (as well as other suspicious plants) and report them as soon as you see them.
Semi-monthly Monitoring
FBL is once again doing semi-monthly monitoring of the lakes. If you are interested in joining us on the water to do testing, drop an email to us at fbl@friendsofboltonlakes.org and we’ll include you on our mailing list.
Article in the Boston Globe Magazine
On May 28th the Boston Globe Magazine published a wonderful article titled “Escape to these hidden lakes of New England” that included our Bolton Lakes. Jeff Harder’s article was well received; thank you to all the FBL members that provided information for the article.

cyanobacteria warning lifted - lakes are fine 6/6/20
Both lakes were tested again this week for cyanobacteria and both lakes came back clean. The health departments that govern the lakes lifted the warning about letting children and pets swim in the lakes. The warning signs at the launches and other access points have been removed.
We will have a more complete discussion of what happened in the summer newsletter.

Algae Blooms MBL and lBL - not a current problem
Alert (5/29/20) from Kim Welch, Bolton Lake Commissioner:
Unfortunately both Lower Bolton and Middle Bolton Lakes have documented cyanobacteria algae blooms based on last week's water testing samples. As a result, the CT Eastern Highland and North Central Health Districts have recommended a health notice be posted. The CT DEEP has issued and posted the signs. The image shown below reflects the actual signs used for this purpose.
The lakes remain open for recreational activity but such activities should not occur where algae is visible. Keep dogs out of the water.
Cyanobacteria conditions can change rapidly, therefore weekly water testing will continue while algae is visible. This algae can produce toxins that could pose a health risk to people and dogs when they are exposed to excessive algae. While these algal conditions exist, please be alert and avoid areas with visible cyanobacteria or algae concentrations and/or scums in the water as well as on the shore and keep dogs out of the water. Please be aware that dogs tend to be more susceptible to cyanotoxins than humans because they often drink lake water and may lick their fur after swimming through a dense cyanobacteria accumulation, which concentrates cells in their bodies potentially resulting in a sick dog.

Update on Aquatic plants in lower and middle bolton lakes
Aquatic plants are a necessary and natural part of the lake ecosystem. Many plants co-exist peacefully with other species and with the people that enjoy the lakes. Some, however, are invasive. While any aquatic plant has the potential to become a nuisance, invasive species are far more likely to do so. They out-compete native plants and can proliferate explosively to disrupt the ecology and recreational use of the lakes.
The attachment provides updated information on the aquatic plants in the Bolton Lakes with a focus on the invasive species found in the lakes. We also discuss two potential invaders, hydrilla and water chestnut. While they are not yet in the Bolton Lakes, they are present in nearby lakes and ponds and pose the risk of turning up here. We ask everyone to be on the lookout for them and report any sightings promptly.
Hydrilla is perhaps the most worrisome invasive plant. According to the Centre for Agriculture and Bio-Sciences International: “[Hydrilla] is one of the most troublesome aquatic weeds in the world.” Hydrilla has been found in the Connecticut river and in nearby Coventry Lake where it was discovered in 2015.
According to New York’s Invasive Species Information website, “[Water chestnut] can form nearly impenetrable floating mats of vegetation … [that] can severely limit light penetration into the water and reduce or eliminate the growth of native aquatic plants beneath the canopy.”
Water chestnut has been found in Vernon in Tankerhoosen, Dobsonville and Talcottville ponds. Because those ponds are so close, the risk of it finding its way to the Bolton Lakes is high. It is unrelated to the water chestnuts commonly used in cooking.
The document linked below has important information that should be of interest to all residents and lake users. It provides more detail on hydrilla and water chestnut and information on the other plants, currently of concern in the lakes. These include curly-leaf pondweed and mudmat in Lower Bolton Lake, and fanwort and variable-leaf milfoil in Middle Bolton Lake. It includes links to authoritative online information and tells how to report any invasive or suspicious plants you see.
Thank you for your interest in the Bolton Lakes and for any monitoring assistance you can provide.

2019 REQUEST FOR CHANNEL CATFISH LAKE MONITORING ASSISTANCE
The Friends of Bolton Lakes (FBL) is asking for your help in monitoring Channel Catfish in Lower Bolton Lake. The vigilance of FBL members and fishermen who reported smaller, possibly juvenile Channel Catfish in Lower Bolton Lake enabled us to alert the CT Department of Energy and Environmental Protection (DEEP) to the possibility that Channel Catfish might be spawning in Lower Bolton Lake. Some Columbia Lake residents have reported that Channel Catfish might be spawning in nearby Columbia Lake.
DEEP suspended Channel Catfish stocking in Lower Bolton Lake after the severe algae bloom in 2012. Between 2007 and 2012, DEEP stocked over 17,000 yearling Channel catfish, a non-native species, into the lake. DEEP netted small Channel Catfish in Lower Bolton Lake during its September 2017 survey. DEEP testing to determine the age of the fish found that the fish they caught were spawned before 2012, the last year of stocking. Although DEEP agreed not to stock Channel Catfish into Lower Bolton Lake in 2019, DEEP wants to resume stocking next year in the spring of 2020. Last October, DEEP indicated that, if stocking is resumed, 700 adult fish might be stocked every 2 years, but nothing has been finalized.
Yearling Channel Catfish between 9 and 12 inches long were stocked into the lake from 2007 to 2012. The fish should grow at a rate of roughly 2 inches per year, but the growth rate has been less than this. Given that the most recent stocking took place in 2012, any Channel Catfish caught in Lower Bolton Lake less than 16 inches in length could have been spawned in our lake.
We are asking you to please forward any evidence you have of Channel Catfish spawning in Lower Bolton Lake.
1. If you observe any nesting sites of the Channel Catfish, please notify us and provide the location.
2. If you catch Channel Catfish less than 16 inches long, please take a photo and measurements to share with FBL, wrap the fish in aluminum foil, put it in your freezer, and contact FBL so we can have the channel catfish tested to determine its age. The smaller the fish, the more likely it was spawned in Lower Bolton Lake.
3. If you have observed a reduction of bass, pickerel or other fish populations in Lower Bolton Lake following the introduction of channel catfish, please email us and share your observations.
4. We are interested in feedback regarding your thoughts on the issue of resuming Channel Catfish stocking in Lower Bolton. Please send your photos, observations, and comments to FBL, friendsofboltonlakes@comcast.net.
You might find the illustrations below helpful in identifying Channel Catfish. Note that unlike Brown and Yellow Bullheads, Channel Catfish have a distinctly forked tail.
Thank you.

Report on the Sediments Nearby the Atlantic White Cedars in Upper Bolton Lake - wednesday, may 22 - 7:00 p.m.
Given the north-to-south waterflow among the Bolton lakes, the health of the upper lake affects both the lower lakes. At 7:00 PM on Wednesday, May 22nd, 2019, at the Notch Road Municipal Center, 106 Notch Road, Bolton, recent UConn graduate Connor Mitchel and his faculty advisor, Will Ouimet, presented the results of their investigations into the sediments in the northern reaches of Upper Bolton Lake. The team made three visits to the lake. Following a reconnaissance visit in fall 2018, the team made two over ice-trips to collect through-ice cores and ground-penetrating-radar measurements.
The project was proposed to the Bolton Lakes Watershed Conservation Alliance (BLWCA) by Debbie Surabian of the USDA Natural Resources Conservation Service. BLWCA, which facilitated the work, contacted Dr. Robert Thorson who arranged for UConn's participation.
The presentation was well attended. Additional information will be posted as available.

volunteers received lake monitoring training
FBL has had an active, ongoing, water-quality monitoring program for the Bolton Lakes since 2014. Now Northeast Aquatic Research (NEAR) has asked for our help in collecting additional data from Middle Bolton Lake. In turn, we requested volunteers to attend lake monitoring training in order to participate in our ongoing three-lake monitoring program.
The work involves taking measurements and collecting water samples in shallow water near the boat launch and spillway, and in deeper water. The intent is to learn more about the flow of nutrients between the lakes.
The Town of Vernon, understanding the importance of this work, sponsored a training session by NEAR for the volunteers. The training was held April 17th. Thank you to those who volunteered and attended the training.

find a suspicious aquatic plant? it is now easier to report it.
We have a new method for finding out what the plant is:
It is very difficult to completely eliminate invasive aquatic plants once they become established. As a result it is crucial that residents, fishermen, and boaters remain vigilant as they enjoy the Bolton Lakes on a daily basis.
If you spot an aquatic plant you suspect is non-native or invasive in Lower, Middle or Upper Bolton Lake, including Cedar Swamp, use our new Suspicious Plant page to report it.
Benefits of the new method:

- It's quick and easy.
- You can report a suspicious plant with your phone when you see the plant (take a photo and fill out the form on the FBL site) or by using your computer (upload a photo to the form on the FBL site).
- The suspicious plant form enables you to enter all required information to help identify suspicious plants.
- You should still gather the sample and refrigerate it in a ziploc bag with enough water to keep it moist in case follow-up is needed.

AQUATIC pLANT sURVEY
The Friends of Bolton Lakes conducted their annual aquatic plant surveys of Lower and Middle Bolton Lakes on 7/20-21/2016. The surveys were performed from pontoon boats circumnavigating the lakes and following up on guidance from lake residents. The great majority of responses to our request for input came from Middle Bolton Lake residents whose concerns included the proliferation of milfoil, pondweed, lily pads, cattails, and phragmites.
The top-level finding is that at the time of the survey Lower Bolton Lake was generally clear of obstructive plants but Middle Bolton Lake has experienced prolific growth of both native and non-native aquatic plants.
The key changes noted in the Middle Lake are:
We submitted samples of the most prevalent pondweed in Middle Bolton Lake to both Northeast Aquatic Research (NEAR) and the CT Ag Station. Both identified the weed as Potamogetan Bicupulatus, also known as “snailseed pondweed.” Unlike milfoil this plant is not likely to spread through fragmentation but it is a prolific seed-producer. A link to a photo looking into one of its beds, taken by a lake resident, is below.
We forwarded our report to Joyce Stille and Kim Welch at the Town of Bolton, John Ward and Steve Krajewski at the Town of Vernon, and Dr. George Knoecklein and his team at NEAR.
Further, we requested that the Town of Vernon ask Dr. Knoecklein to look into the current Middle Lake situation as soon as possible to determine what may have caused the dramatic change in the conditions there and what might be done to address it.
The documentation of our surveys is attached. In the report you will find maps showing the routes taken on Lower and Middle Bolton lakes and tables of the plants spotted at each observation point.
Thanks to all who provided input to help focus our survey and for your continued support.
The top-level finding is that at the time of the survey Lower Bolton Lake was generally clear of obstructive plants but Middle Bolton Lake has experienced prolific growth of both native and non-native aquatic plants.
The key changes noted in the Middle Lake are:
- A significant increase in water clarity well above historical norms;
- widely distributed rapid growth of pondweed and re-growth of variable leaf milfoil;
- obstruction of some waterfront properties by phragmites/cattail beds and lily pads.
