Umbagog Lake is a pristine 7,600-acre lake straddling the border between New Hampshire and Maine in the northeastern United States. As the lowest of the Rangeley Lakes, Umbagog features an average depth of approximately 12-15 feet, with some deeper sections reaching up to 50 feet, particularly in the northeast section near Sunday Cove. With over 50 miles of shoreline and extensive wetland complexes, Umbagog is known for quality smallmouth bass fishing but also supports populations of trout, perch, bass, salmon, and pickerel. Much of the lake falls within the Umbagog National Wildlife Refuge, established in 1992 to conserve the wetlands and surrounding habitats. This wilderness setting creates an excellent fishing destination with a variety of aquatic environments from open water to river confluences.
