Watershed Assessment

A watershed is defined as an area of land that drains to a common water body. Depending on the scale of the watershed you are looking at this could be a small brook, a stream, a large river, or, for our purposes at LSM, a lake. Because the health of a lake is heavily influenced by the geologic makeup, land use activities, and level of development that takes place in that lake’s watershed, it is a critical aspect to understand for stewardship activities.

To help address issues taking place in the watershed, LSM offers several trainings and provides educational resources.

For more information about watersheds, please look at our watershed FAQs document. It can be found HERE.

LSM offers watershed assessment trainings annually in conjunction with Maine DEP staff. More information pertaining to these trainings can be found HERE.

LSM in conjunction with Maine Lakes offers a Small Watershed Grant. Information and application can be found HERE.

• LakeSmart is an education and outreach program that rewards lakefront homeowners who manage their land to protect water quality. The program is free, non-regulatory, and voluntary. Participating homeowners receive individualized suggestions for keeping pollutants from stormwater out of lake waters. LakeSmart is operated by the Maine Lakes non-profit organization.
