spring newsletter
Dear Friends and Neighbors,
The ice is out and the lakes are starting to refill. Here are some things that are happening on our lakes.
Hatch Hill Dam
The Hatch Hill dam project has been completed. The dam will allow free flow of water between Upper Bolton Lake and Middle Bolton Lake, while maintaining a constant level in Upper Bolton Lake. In addition, there is an easier, safer trash rack that should stay clear despite the best efforts of the beavers as well as a permanent spillway that does not require seasonal maintenance. This project was a major goal for FBL and took several years of work with the DEEP (Department of Energy and Environmental Protection) and other stakeholders to reach completion.
Watershed Management Plan
The Bolton Lakes Watershed Management plan has now gone to the DEEP for final approval. Thanks to all who participated during the draft’s comment period; your suggestions greatly improved the final version. A copy of the current version of the plan has been posted on the FBL website. Approval of the Watershed Management plan isn’t expected right away due to reassigned and reduced staffing at the DEEP.
In anticipation of final approval, we are finalizing an implementation roadmap for the Watershed Management plan; this will be posted on the FBL website when complete. A huge thank-you to Paul Weisser for all his efforts in creating this implementation roadmap.
Fill-up
The fill-up of the lakes began on March 16th, and they should be restored to normal surface levels by the middle of April. It began with the closing of the valve at the outlet of Lower Bolton Lake, followed by closing the valve between Middle Bolton Lake and Lower Bolton Lake. The upper lake, which accommodates the bulk of the watershed in-flow, is maintained at a constant water level.
AIS Grants
The state Aquatic Invasive Species Grant for 2021 (awarded to Vernon, Bolton, and FBL) funded treatment of invasive aquatic species. In addition, the funding was used to erect signs on our local roads marking the edge of the watershed; most of them have been installed. Soon signs will be installed at the boat launches warning about the threat of aquatic invasive species specific to our lakes: milfoil, fanwort and curly pondweed.
More recently, the two towns and FBL applied for a 2022 AIS Grant. This year’s application requested additional funding to maintain control of algae blooms, chemical treatment (only when necessary), consulting fees, and data collection and analyses. We should hear soon if we are awarded funding.
Lake Monitoring
The FBL team of volunteers will start testing the lake water in mid-April. The testing occurs twice a month from now until mid-October. Anyone interested in helping the team by piloting a boat and/or recording data, please contact John Williams at fbl@friendsofboltonlakes.org.
New Invasive Reporting Tool
The invasive reporting tool on FBL has been updated to include reporting of more than just plants. Check it out on our webpage here.
Harmful Algae Blooms
Last summer ended with several harmful algae blooms (HABs) caused by a number of environmental reasons. Our lakes were not alone in Connecticut. The combination of heavy rains and wind caused our lakes to be ripe for HABs. While we can’t control the weather there are steps we can take to help prevent HABs.
If you suspect there is a HAB, first keep people and pets out of the water. Then do one of the following:
Here are some web references:
The CDC site is here and a video to help identify blooms is here .
Bloomwatch App
Cyanobacteria associated HABs and the toxins they produce are an increasing concern across the country. The frequency of occurrence is increasing and their toxicity over the years has been associated with numerous human and animal health issues. This has direct implications to the use of recreational water bodies for contact recreation, the susceptibility of public water supplies to HABs and their toxins, and the overall ecological degradation of aquatic resources.
The US EPA developed the BloomWatch ‘App’ as a part of the Cyanobacteria Monitoring Collaborative (CMC) program to engage the public to report when and where potential cyanobacteria blooms appear. It utilizes crowdsourcing to find and report potential cyanobacteria blooms.
The CMC program has three overlapping components or tiers: A bloom watch/tracking component, a cyanobacteria identification and documentation component, and a cyanobacteria monitoring component. Each expanding tier has a specific component objective associated with it. The BloomWatch tracking component was developed to enable lay people, citizen scientists, and the like to be able to report on the presence of a bloom with the use of a smartphone App. This tiered approach provides important information on where, when, and potentially for how long blooms are occurring.
The main objective of BloomWatch is to photographically document the location and time of a bloom for further verification. Because of logistics and the variability of when and where HABs may occur, (blooms may only be visibly present for a few hours or less and at specific locations within a particular waterbody) it is imperative that efforts be made to engage the public’s help. Local knowledge of where and when blooms are occurring is likely under-reported, or not reported at all. When blooms are reported to a state water quality or health official, by the time officials can reach the location the bloom has often dissipated or shifted from its prior location. Local citizens are usually the first to encounter a bloom condition, as they often occur in the early morning hours while individuals are out walking their dogs, getting in a morning run, or getting ready for the day’s work. Images can be taken at any time and consist of three images per submittal and follow a prescribed format.
The BloomWatch app is very easy to use:
Once you've started using the App it's easy.
Please continue to use the FBL website feature to report invasive aquatic plants. The BloomWatch App should be used only to report algae blooms. Thanks!

draft bolton lakes & watershed management plan
The goal of the management plan is to provide uniform, thoughtful management of the entire watershed and lakes system now, and to offer recommendations for the future. Hillary Kenyon, a professional limnologist and Certified Lake Manager from Northeast Aquatic Research (NEAR) drafted the main body of this plan. In 2020, the towns of Bolton, Vernon, Coventry and Tolland along with representatives of the Friends of Bolton Lakes and the Bolton Lakes Watershed Conservation Alliance comprised a steering committee who collaborated with Ms. Kenyon to complete the plan.
The Directors of FBL remarked, “This body of work is the culmination of many years of research, data gathering and unyielding cooperation from numerous state and local town officials”.

Happy New Year from fbl - winter newsletter
Happy New Year from the board of the Friends of Bolton Lakes. In this newsletter we would like to review 2021 and look ahead to 2022.
2021
Aquatic Invasive Species (AIS) Grant: The FBL, along with the towns of Vernon and Bolton, applied for and were awarded an AIS grant from the Department of Energy and Environmental Protection (DEEP) for $24,910.50. The funds from that grant will be used to manage and monitor invasive plant species, provide water quality testing, offer public educational outreach, purchase equipment, and provide AIS signage at both boat launches and signs that delineate the watershed on major roads.
Watershed Management Plan: The watershed management plan that started at the end of 2020 was completed in 2021. The main body of this plan was drafted by Northeast Aquatic Research (NEAR), the professional limnology team responsible for our lakes. FBL was intimately involved with getting the plan started, participating on the steering committee, and providing data input from the monitoring group. The final draft of the plan will be placed on our FBL website and the websites of the four towns in which our watershed lies (Tolland, Coventry, Vernon, and Bolton) by mid-January. There will be a two-week public comment period. The steering committee will integrate suitable public comment into the plan, after which point it will be submitted to the DEEP. Uniform, thoughtful management of the entire watershed is a goal of FBL and we hope this document will serve us well in the future.
Hatch Hill Dam: At the very end of 2021, the Hatch Hill dam reconstruction project was almost completed. The new dam will improve control of the level of Upper Bolton Lake protecting Hatch Hill from flooding. It will also make general maintenance safer and easier at the dam. At this point the contractor is waiting to get the trash rack and weir gate installed.
Invasive Plant Treatments: In mid-June, the Lower Lake was treated for curly pondweed. The treatment was mainly successful but some small patches near the spillway remain. Toward the end of August, the Middle Lake was treated for fanwort and milfoil. Thank you to everyone who used the invasive species reporting tool on the FBL website; we received over 100 observations this year. Those observations are what FBL used to keep the towns and the lake consultant informed of the condition of the lakes. Your input is vital to keeping our lakes in good shape.
Algae Blooms: In May, the green algae was prevalent in both the Middle and Lower Lakes. Although not poisonous, it was thick on the surface of the water. By mid-July we started seeing signs of blue-green algae or cyanobacteria. This can be harmful to animals and people. Lower Bolton Lake was closed at the end of July for a period of time and again in early September by the local health department. Both lakes had considerable algae that did not dissipate until well after the drawdown. Our lakes were not alone; many lakes in Connecticut had to deal with algae blooms this past summer. The unusually heavy rains this spring and summer brought a lot of silt into the lakes and the winds kept them stirred up providing ideal conditions for the cyanobacteria to thrive. At this time, the Department of Public Health has removed all notifications of lake closures.
Monitoring: The science committee again did bi-monthly monitoring of the Middle and Lower Lakes, starting in mid-April and finishing in mid-October. Every two weeks volunteers measured the clarity on both lakes at the deepest point and then measured temperature, oxygen level and pH at .5-meter intervals from 0 to 5 meters. In addition, once-a-month water samples were taken at two or three levels and the water samples were delivered to NEAR for chemical analysis. We also have two passive monitoring systems. On both lakes we have depth monitors that check the depth of the lake every hour. And we have two sets of temperature and light monitors strung on buoys that we deploy during the summer. You may have seen the buoys anchored at the deep spots in each lake. On several occasions we responded to emergency calls to take samples for cyanobacteria counts. All our data is shared with NEAR for their use in the management of our lakes.
Spring and Fall forums: This spring we had a virtual forum where the results of the aquatic plant survey of Middle Lake (done in the fall of 2020) were presented by Greg Bugbee from Connecticut Experimental Agriculture Station. In the fall we had a virtual forum that included the annual business meeting and a presentation from DEEP on the Hatch Hill dam reconstruction project.
2022
Membership: Membership for 2022 is now open. You may renew your membership at the FBL website here either using the webform or downloading the form and mailing it to Friends of Bolton Lakes, Inc., P.O. Box 1385, Manchester, CT 06045.
Monitoring: We will continue to monitor as above. In addition, this year we plan on obtaining water samples to count algae during the summer months. Anyone interested in participating is welcome. Please email FBL at fbl@friendsofboltonlakes.org.
Spring and Fall forums: Depending on public health conditions these will either be virtual as in 2021 or in person. An agenda will be developed as we approach the date of the forums.
The Friends of Bolton Lakes will continue its collaboration with the towns, the state DEEP and our legislators to ensure that our goals are achieved. Let’s again challenge ourselves to make our collective voices heard by participating in our energetic organization. The meetings are held at 6:30 PM on the third Wednesday of each month.
Have a healthy and prosperous New Year.

middle and lower bolton lakes water quality
FBL has been closely monitoring the lakes’ water quality conditions throughout the year. We have been coordinating with the towns, the lakes’ limnological consultants, the lower lake commissioner and the health departments. Water testing is an ongoing effort by FBL’s volunteer science committee. In addition to bimonthly testing, they have collected samples for cyanobacteria cell counts when conditions warranted. Cyanobacteria, E. coli measurements, and the appearance of surface scum continue to be evaluated to determine if remediation is necessary and when the waters are safe for humans or animals. The town’s limnologists investigated surface blooms and water clarity on both lakes this week.
Lower Bolton Lake restrictions rescinded - 9/23
September 23rd the town of Bolton published a bulletin from the Eastern Highlands Health District. After visiting the lake again, the EHHD rescinded all the restrictions applied earlier in the week to Lower Bolton Lake.
Tuesday a member of FBL and the Bolton Lake Commissioner, Kim Welch, took a water sample from Lower Bolton Lake to the office of Northeast Aquatic Research for testing. The cell count showed that the level of cyanobacteria was well below the unsafe limit.
Nevertheless, common sense should always be applied. If there are visible signs of algae on the surface of the water, avoid swimming and letting your pet(s) play in the water. And, as always, report any sightings using the Suspicious Plant Reporting Tool on the FBL website.

Bolton Lake Residents, Friends and Neighbors,
The excessive rain and its runoff into the lake, high temperatures and calm water are likely contributing to this season's early and extended algal bloom.
Lower Bolton Lake(LBL): This week’s LBL water sample cyanobacteria cell count results are high, but not high enough for an official health alert, so I am writing this to make you aware of the current conditions and the associated concerns you need to be aware of. Two water samples were collected 8/25/21 and the cyanobacteria cell counts are 77k and 62k. The threshold for a formal health alert is 100k.
Cyanobacteria, aka blue green algae, creates toxins that are deadly for dogs and can be harmful to humans resulting in skin rash, respiratory and GI issues. Please keep dogs out of the water while this algae is present and limit human exposure to avoid the above mentioned health issues.
Educate yourself. Use these links so you can be aware of the concerns the current LBL water conditions produce. For additional facts about cyanobacteria blooms:
From the CT DPH:

From the CDC, which suggests, when in doubt, it's best to stay out!
https://www.cdc.gov/habs/pdf/cyanobacteria_faq.pdf
Many thanks to several lake residents and visitors that have shared their concerns with me about the current water conditions. Your concerns are being heard. There are volunteers and lake experts watching the conditions closely and assisting us with water sample collection and analysis, I want to thank them as well.

DEEP and DPH Advise Against Swimming or Other Water Contact Recreation up to and including Wednesday 8/25 Due to Tropical Storm Henri's Impact
In a press release issued on Sunday, August 22, the Connecticut’s environmental and public health officials state:
“Given the significant rainfall that occurred (and is still expected) due to Tropical Storm Henri, many areas across the state have experienced discharges of untreated sewage. The Connecticut Department of Energy and Environmental Protection (DEEP) and the Connecticut Department of Public Health (DPH) are advising against direct contact with surface water in areas in close proximity to drainage pipes statewide, particularly in urban areas such as Bridgeport, Hartford, Norwalk, Norwich, and the greater New Haven area over the next 72 hours in Connecticut’s streams and rivers. Residents are advised not to swim, fish, or utilize paddlecraft in these areas.”
Although the press release refers to urban areas, after speaking with the North Central Health District, we thought it prudent to provide this information out of an abundance of caution, the large drainage area of the lakes, the presence of agriculture nearby, and recent water quality issues in the lakes.
Since the press release was issued Sunday, this advice would apply up to and including Wednesday August 25th.

MBL and LBL updates 8/10/21
Middle Lake Update:
There will be a treatment for fanwort on the Middle Lake this week. There has been a substantial amount of fanwort located near the boat launch and one spot on the southwest shoreline. Since fanwort spreads by fragmentation, try to avoid driving boats through these areas.
Lower Lake Update:
The Eastern Highlands Health District has still closed Lower Bolton Lake for swimming due to a blue-green algae bloom. The lake is tested weekly and the lake will open once two consecutive tests show that the level of cyanobacteria in the lake has dropped back below the threshold. Go here to reach the CT DEEP page with information on blue-green algae blooms.

Bolton Lakes current conditions include invasive plants - 6/8
Dear Friends and Neighbors,
The following is a message from Kim Welch, the Bolton Lake Commissioner. There are pictures of the two invasive species mentioned below. The first one is fanwort and the second is curly pondweed
FBL
Bolton Lake Residents, Friends and Neighbors,
Lake Use - There are no use restrictions for boating, fishing or swimming in the Bolton Lakes. The lakes remain open for recreational activity, including swimming, but such activities should not occur where algae is visible. Keep yourself, your children, and your pets out of the water where algae scum is visible.
Middle and Lower Bolton Lakes Have Invasive Plants
Lower Bolton Lake - Spot treatment for Curly Pondweed on June 15th
There is an abundance of curly pondweed along the shorelines of Lower Bolton Lake. Unfortunately, this is an invasive plant species. Curly pondweed plant leaves are small (3 to 4 inches long), narrow (like pencil width) and have curly (like lasagna) edges. The Town of Bolton has been monitoring and managing this plant species for a few years. There is a spot treatment scheduled for June 15th to eradicate this invasive plant. Please plan for use restrictions on the 15th and shortly thereafter. I will provide more details on the use restrictions related to this treatment in the coming days. When using the lake, please stay out of the weeds/plants so that we can minimize the spread of them. If you find floating fragments of these invasive species, please remove them from the water and discard them or place them in your compost, away from the lake.
Middle Bolton Lake - Fanwort is found near the Hatch Hill boat launch
Some free-floating fanwort, which is an invasive species, was found near the Hatch Hill boat launch at Middle Bolton Lake. it is being monitored and managed. Fanwort has leaves that look like small fans that are about the size of a quarter coin. Again, when using the lake, please stay out of the plants/weeds so that we can minimize the spread of them. If you find floating fragments of these invasive species, please remove them from the water and discard them or place them in your compost, away from the lake.

Middle and Lower Bolton Lakes Have Visible Algae - 5/19
Both Lower Bolton and Middle Bolton Lakes have algae and pollen visible on the surface and in the water column at this time. The algae in the lakes are a mixture of toxic and non-toxic species. These conditions are being monitored closely by our lake resident volunteers and our lake limnology consulting firm (NorthEast Aquatic Research). Connecticut’s Department of Energy and Environmental Protection, our local health districts, and the Towns of Vernon and Bolton have been informed of the current lake water conditions.
The lakes remain open for recreational activity but such activities should not occur where algae are visible. Keep yourself, your children, and your pets out of the water while algae are visible.
Algal conditions can change rapidly; water testing will continue while algae are present. Cyanobacteria algae can produce toxins that could pose a health risk to people and dogs when they are exposed to excessive amounts. While these algal conditions exist, please be alert and avoid areas with visible cyanobacteria or algae concentrations and/or scums in the water or on the shore; also, 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 lick their fur after swimming through a dense cyanobacteria accumulation, which concentrates cells in their bodies potentially resulting in a sick dog.

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 Suspicious Plants" 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.

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.

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.

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 Plants 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.
