Lake Sherburne is located in the Many Glacier region of Glacier National Park, in the U. S. state of Montana. The lake is a reservoir, formed by Lake Sherburne Dam, which impounded Swiftcurrent Creek and was constructed in between 1914 and 1921. The construction of the dam inundated several small lakes and highly productive riparian and wetland areas, and due to its fluctuating water levels, the surrounding area supports little vegetation. However, trumpeter swans are often observed along the lake in the spring and fall. The lake stretches nearly 6 miles (9.7 km) when full. The reservoir is the principal water storage component of the U.S.
