Thompson Lake Watershed Survey 2023

The 2023 Watershed Survey Report is now available!

In May of 2023 TLEA volunteers and Technical Leaders surveyed the entire watershed of Thompson Lake. This nonregulatory survey was done to identify erosion sites and develop a Watershed Protection Plan for the next 10 years. We identified 299 sites that had significant erosion. Erosion, a form of non-point source pollution (NPS) is the biggest threat to the water quality of the lake. Property owners can go to the “Watershed Survey” page under “Programs” on this website to see the results of the survey. The Report lists sites of erosion, their level of impact, and what kind of remediation measures are recommended. Check it out by clicking:

Jim YCC ConfLearn more about Youth Conservation Corp crews who focus on erosion-control efforts and other activities that improve lake and water quality. At the Maine Lakes Conference in 2023, Whitney Baker from 30 Mile River watershed association shared an overview of the YCC program, and her perspective from a staffed regional watershed organization. Jim Skinner from Thompson Lake Environmental Association will share his perspective from a lake association that relies on volunteers to run and manage the program. Both speakers will share “lessons learned”, ideas for success, and some of the challenges they’ve faced organizing YCC crews for their lake and their region.
More information can be found at the Maine Lakes Conference website.
