SUMMARY PRESENTED BYT-Mobile

Gravel roads and low water levels define the experience at Flat Lake, a drive-in, walk-in, and boat-in site within the Fort Peck Recreation Area managed by the Army Corps of Engineers. The lake level runs low, and the surrounding terrain is dry and open. Vault toilets and a boat ramp are on-site, along with fire rings and picnic tables, though the number of spaces is limited. Pets are welcome, and trash service is provided. Anglers and boaters looking for places to camp near Fort Peck Recreation Area will find this a functional, no-frills base worth considering.

Primitive with good lake access

VAult toilets, boat ramp, beautiful lake.  No potable water, no electricity, etc.  Some fire rings and picnic tables, limited spaces.  Area is DRY and water level is low, but still a great area.  We'll kept grounds.
