7/19/2025 - Loon Count Recap: A Beautiful Morning on the Lake

It was a beautiful morning on Lake Winnecook for the 42nd Annual Audubon Loon Count, with flat calm waters and temperatures in the low 50s. At 7 a.m., 23 volunteers launched their boats and kayaks, armed with binoculars and keen eyes. With just 30 minutes to survey the lake, they recorded 14 adult loons and 2 chicks—just short of last year’s count of 16 adults and 2 chicks.


The June 26th Special Membership Meeting at Stone Tree Farm and Cidery in Unity was a tremendous success!
The event drew a record-breaking crowd and we’re thrilled to report that the kickoff of the

For the Love of Our Lake - Let’s Make It Clean, Not Green” Campaign

Watershed Survey: Final Report

The link below will display the Final Report of the Unity Pond Watershed Survey, which was conducted last year. The report will provide our members with insight regarding the sources of pollution around the Watershed, a list of properties that have been identified as potential risks, as well as suggestions on how to rectify the issues found.

The protection of the watershed should be an effort undertaken and supported by the entire Lake Winnecook community, especially after the announcement by the Maine DEP regarding the PFAS contamination.
