Big Stone Lake, Minnesota & South Dakota, USA
Big Stone Lake’s sparkling blue water covers 12,360 acres and forms the border between western Minnesota and northeastern South Dakota. This picturesque lake dates back 20,000 years to the last ice age when glacial Lake Agassiz passed through the Traverse Gap and emptied into glacial River Warren. The valley of that prehistoric river is now Big Stone Lake. Scientists have discovered skeletons of humans that lived near the lake 12,000 years ago, and there is proof that an Indian-like people made their home near the lake in ancient times. Big Stone Lake gets its name from a Sioux word for the granite that was found in a nearby Minnesota Valley.
Big Stone Lake is fed by the Little Minnesota River from the north and by the Whetstone River from the south. Big Stone Lake is the source of the Minnesota River; flow from the lake to the Minnesota River is controlled by the Big Stone Lake Dam, which is owned and operated by the State of Minnesota. The 26-mile-long freshwater lake, which is approximately one mile wide and 965 feet above sea level, is also a reservoir for the Minnesota Valley. In addition to recreation, Big Stone Lake provides for fish and wildlife propagation, livestock watering, and irrigation.
A favorite spot for boaters, swimmers and anglers, Big Stone Lake has an average depth of 8 feet with a maximum depth of 16 feet. Sixty-two miles of emerald green shoreline are dotted with fabulous vacation resorts, boat launches, and 12 public access areas for fishing. If fishing is what brings you to the lake, you will delight in the abundance and variety of fish species: walleye, white bass, northern pike, bluegill, crappie, rock bass and over 30 other species can be found in Big Stone Lake.
Two magnificent state parks near the lake–Big Stone Lake Park in Minnesota and Hartford Beach State Park in South Dakota–offer visitors and residents a never-ending selection of fun and entertainment. Picnic areas, boat launches, camping facilities, swimming areas, and walking and hiking trails can be found at both parks. Sunbathers can soak in some rays at the water’s edge or while out on a boat.
