Dear Lake Neighbors and Friends,
We hope this letter finds you well. Here is a brief update on the major initiatives the GLA is involved in. As always, we rely on the support of members like you to help further our mission of restoring and preserving our lakes. Thanks in advance for your continued support of the GLA.

Lost Lake/ Knops Pond: The focus for Lost Lake and Knops Pond this year is to maintain the quality of water that we have enjoyed for the past few years since the herbicide treatment program began in 2013. Each year a maintenance or spot treatment is needed in order to keep the invasive weeds at bay. Our partner, Solitude Lake Management has developed a treatment plan for this season. This year’s treatment plan will include the use of Diquat herbicide for the Curly Pond Weed, Milfoil and Bladderwort throughout Lost Lake and Knops Pond. Fanwort has spread beyond the area where a spot treatment can be effective so this year, we are skipping the Fanwort spot treatment and saving up for a whole lake treatment next year. This means the Fanwort will be allowed to grow this season and you will likely see it become more prevalent. We have the option again this year to apply Copper Sulfate to combat algae blooms if needed. As always, the treatments are done in accordance with the State and Town regulation. The treatments have not been scheduled yet and notifications will be made in advance.

Payment for the annual spot treatments fall 100% on the GLA. The Town funds appropriated in 2013 have been exhausted and it is up to us to fund the annual herbicide treatments. This year’s treatment costs are estimated at $16,000. At the time of this letter we have a budget shortfall of about $10,000. Next year’s full lake treatment could cost between $80,000 – $100,000. We are very fortunate to have generous donors like yourselves who rally for a cause like this- Now is the time when we really need your support to pay for this year’s treatment and begin saving up for next year.

Baddacook: Last summer was year 2 out of 3 for the pilot program to control the weeds, clear out high bio-mass areas and improve access points into Baddacook Pond by Mechanical means. This is being done in in cooperation with the Groton Water Department and the DPW. The mechanical means were weed harvesting and hydro-raking. Although these do not produce the impressive results achieved in Lost Lake, they are a very beneficial step forward for Baddacook. Pond conditions have dramatically improved for recreational users and wildlife. Trailers don’t come out loaded with invasive weeds that could spread to other lakes. Also, nutrients are being removed and Cabomba isn’t allowed to flower which can slow weed growth. The GLA has been supporting this with people and equipment, such as the Weed Harvester.

This is a 3-year CPA funded pilot program which will be continue this year. However, next year the CPA grant will be over and further funding will require an increase to the Town Harvester committee budget. Please come and support lake management projects like this and associated funding requests at Town Meeting. Its a way to fund management of our lakes and ponds that benefit everyone in Groton.

Three years ago, we increased the annual membership dues to $50. The reason for the increase was quite simple- funding the annual herbicide treatment to maintain our lakes at the current quality requires more money than we’ve been able to raise annually. The historic $25 membership does not cover the costs any longer. Annual herbicide treatments will cost between $15,000 and $35,000 per year to treat Lost Lake and Knops Pond. Please consider making a generous contribution this year to maintain the quality of our lake system. An average donation of $150.00-$250.00 per household will help guarantee the success of our lake treatment program. Every contribution matters so please do what you can to help out.

We need the entire Groton community’s help to bring all these efforts to fruition, both financially and personally. Please support the Groton Lakes Association in any way you can. Please give generously so that we can make and keep our lakes healthy. If you have any expertise (e.g., legal, grant writing, webpage design and updates, botany, ecology, etc.) that could be helpful to our shared efforts, please volunteer and join the GLA team.

Please consider sharing this letter with your friends and neighbors who enjoy the lakes and encourage them to contribute to the GLA in order to maintain the water quality in our lakes.

Thank you for your support,
-Groton Lakes Association
