Lewis and Clark Lake

Lewis and Clark Lake is a reservoir formed by damming the Missouri River between South Dakota and Nebraska, creating a long body of water with varied shoreline features. The water is surrounded by rolling terrain, sandy banks, and wooded areas that change as you move along the shoreline.

The Army Corps of Engineers built Gavins Point Dam across the Missouri River in 1957, creating this reservoir where a flowing river once existed. The construction marked a major change to the landscape and hydrology of the region.

The Lewis and Clark Visitor Center atop Calumet Bluff presents exhibits about Missouri River Basin history and regional wildlife populations.

You can access the lake at multiple public areas along both shores where boat ramps and parking are available. Spring through fall offers the most comfortable weather and full access to all recreation areas.

The lake gradually loses water storage capacity each year as sediment from upstream areas settles on the bottom. This slow filling process is a quiet reminder of how nature continuously reshapes reservoirs over time.
