Thompson Lake is a premier 4,426-acre fishing destination located in Oxford County, Maine, spanning the towns of Otisfield, Oxford, and Poland. With its maximum depth of 121 feet and 50 miles of scenic shoreline, this lake offers some of the finest salmon, lake trout, and bass fishing in the state. The lake's diverse habitat includes deep drop-offs ideal for coldwater species, rocky shorelines that provide excellent smallmouth bass structure, and shallow areas at the northern and southern ends that support thriving largemouth bass populations. Thompson Lake maintains excellent water quality with sufficient dissolved oxygen to support fisheries throughout the water column, even during the warmest summer months.
