Willimantic Reservoir Watershed

What is a watershed?

A watershed is a region or area bounded peripherally by a divide and draining ultimately to a particular watercourse or body of water. More simply, an area or perimeter of land that "drains" or "sheds" to a body of water. 

The Willimantic Reservoir watershed is 166 square miles in size and encompasses 11 towns located north of Mansfield Hollow Lake and our Willimantic Reservoir. 

These towns include: Ashford, Chaplin, Eastford, Hampton, Mansfield, Pomfret, Scotland, Union, Willington, Windham, and Woodstock. 

Although these 11 towns are included in our drainage basin, some of them are only partially located inside due to their geographical topography.

For Projects Within the Willimantic Reservoir Watershed

Windham Water Works requires any projects happening within the watershed boundaries to be reported to us before the work starts. The reason for this is so we are aware of any potential threats or issues the work may pose to the quality of our source water which we treat to make potable drinking water. Windham Water Works supplies drinking water to Willimantic, parts of South Windham and North Windham, along with areas of Mansfield. Attached below is the Project Notification Form.

It is not only important to think about the environment for the safety and quality of our most valuable resource, but for the future of our planet as a whole. Thank you!
