Thomas Lake is a 32 acre hard-water seepage lake located three miles west of Amherst Junction in the Town of Stockton. The estimated volume of the lake is 540 acre-feet, with a shoreline length of 0.84 miles. The littoral zone has a sand bottom, and is covered with dense aquatic vegetation to a depth of about fifteen feet. The lake’s maximum depth is 28 feet, with an estimated retention time of 7.3 years. In the past the lake has been intensively managed for fish with chemical treatment and restocking projects. The sport fish population is presently dominated by bluegill, largemouth bass and yellow perch. Light erosion along the bank occurred in the past from pasturing cattle adjacent to the water. Public access is present on the south side, including an unimproved boat launch area. Residential development has increased dramatically since 1968.
