Algae & Grass

The link below is for the Maine Department of Environmental Protection web site. Each season we see an increase in algae in our lake that sometime appear similar to balls of cotton candy or just very small, suspended particles. This article reviews the concerns about cyanobacteria (formerly known as blue-green algae). Our Volunteer Lake Monitor, Steve Triggs, periodically measures the clarity of the lake water using a Secchi Disk. As algae concentrations increase, the clarity decreases and the Secchi Disk reading decreases. The article talks about performing a “jar test” to help determine if the algae concentration is of concern. I tried this recently and found the water to be clear, but you might want to try it yourself.

Recently we again have seen a large amount of grass floating on the surface of the lake and washing ashore in large clumps. We also saw this several years ago and it is unrelated to the milfoil removal done in early July. You may gather and compost the grass, if it is a problem on your shoreline, the same as you would collect the milfoil that may float ashore.

Hannaford Community Bag Program

Collins Pond Improvement Association To Benefit!

You can help our mission to protect & conserve the natural resources of Collins Pond and its shorelines, water quality & watershed by spreading the word!

The Hannaford Community Bag Program is designed to give back to the local community with every reusable bag purchased. Every $2.50 reusable Community Bag sold supports a non-profit local to the store in which it was purchased. This program offers a way for shoppers to give back as part of the regular weekly routine.

Every month, at every Hannaford location a different local non-profit is selected to benefit from the sale of these special reusable Community Bags. Collins Pond Improvement Association was selected as the August beneficiary by local store leadership at the store located at Windham. CPIA will receive a $1 donation for every $2.50 reusable Community Bag purchased at this location in August.
