The reservoir holds walleye, northern pike, bass, and panfish. You can fish from shore or launch a boat at one of the ramps. The western side remains undeveloped and attracts migrating waterfowl twice yearly. Birders come for warblers and other songbirds moving along the Cheyenne River corridor. The lake is the only large water body in this isolated stretch of arid country. Wildlife concentrates here during migration seasons.

An entrance fee applies year-round. You camp at developed sites managed by South Dakota's Department of Game, Fish and Parks on behalf of the Bureau of Reclamation. Reservations and current fees vary by season and site. Call ahead to confirm which campgrounds are open and what you'll pay.

This corner of South Dakota gets hot and dry in summer. Winter can shut down road access or close some facilities. You should verify current campground status and any seasonal closures before you drive.
