Lake Sakakawea State Park is a public recreation area occupying on the southern shore of Lake Sakakawea in Mercer County, North Dakota. The state park is located adjacent to the Garrison Dam, 1miles north of Pick City.
The park was originally developed by the U.S. Army Corps of Engineers as Garrison Lake State Park. The North Dakota Parks and Recreation Department assumed management in 1965, then expanded the park, renaming it Lake Sakakawea State Park in 1973.
The park offers hiking, swimming, fishing, boat ramps, marina, cabins, and campgrounds. The park's hiking trails include the western terminus of the 4600miles North Country National Scenic Trail which, when completed, will cross the northern tier of the continental United States from its eastern terminus at Crown Point in upstate New York.
