Big Pine Lake is a 4,730 acre mesotrophic (moderately fertile) lake located in northeastern Otter Tail County approximately 3 miles east of Perham, MN. Big Pine Lake is part of the Otter Tail River Watershed and is connected to Little Pine and Rush Lakes via the Otter Tail River. The Otter Tail River inlet is located along the northwest shoreline while the outlet is located along the west shoreline of the lake. Minnesota DNR controlled dams at the outlets of Little Pine and Big Pine Lakes impede navigability between this chain of lakes. The maximum depth of Big Pine Lake is 76 feet and half the lake is less than 15 feet deep. Largemouth bass, northern pike and walleye are the primary game fish. Back in 2011, the Minnesota DNR did a status of the fishery and the walleye numbers were very impressive. Panfish include bluegill, crappie, rock bass and perch.
