Deadmans Basin Reservoir Professional Review and Guide
"Deadmans Basin Reservoir is a designated fishing access site. It is a 1,900-acre Musselshell River bottom reservoir that reaches a depth of 64 feet at its deepest point. This is a rather bleak spot, but excellent for rainbow and big browns. It is generally a fairly open body of water. Nearby are extensive recreational facilities, including boat access, toilets, campground, picnic area, and shelters. Nonetheless, Deadmans Basin receives only limited use.
Because this open reservoir lies in a wind swept prairie area, sudden storms do pose a hazard to anglers, swimmers, and boaters, so be watchful. Deadmans Basin is primarily a trout and kokanee fishery, with rainbow predominating. Some brown trout do migrate from the Musselshell River, so anglers should be able to pick one up every once in a while. FWP has planted rainbow trout for the past eighteen years. In 1972-1973, FWP planted some Coho salmon. The rainbow have flourished in the reservoir, but the Coho seem to have disappeared. In 1984, FWP switched to kokanee and still plants about 100,000 each year."
