Lake De Smet is a public lake in Johnson County, Wyoming, managed by Wyoming Game and Fish Department. It is public water managed for fishing by Wyoming Game and Fish.
Lakes and reservoirs across the Rocky Mountain region typically hold rainbow, brown, cutthroat and brook trout, with kokanee salmon and lake trout present in many of the larger reservoirs -- species commonly documented across the region's public waters by state wildlife agencies.
Lake De Smet covers about 1,980 acres in the Sheridan Region (Bighorn Mountains & Powder River) region. The nearest other mapped waters on PiscaMaps are Desmet Lake and Leiter Ditch Pond.

Anyone 14 or older needs a Wyoming fishing licence — the resident annual is about $27, the non-resident annual about $102 (Wyoming's non-resident fee is one of the highest), with non-resident daily (~$14) and 5-day options. A Conservation Stamp (about $21.50, valid multiple years) is also required. Wyoming residents 65 and older buy a discounted licence; under-14 fish free with a licensed adult. Buy from Wyoming Game and Fish at wgfd.wyo.gov. A Wyoming fishing licence plus a Conservation Stamp covers this water — it is on WGFD's Fishing Guide. Wyoming grants no public right to a private streambed: where a stream crosses private land, fish from public land, a WGFD walk-in or Public Access Area, or a bridge right-of-way.
Every water carries species, bank & boat access, current regulations and live water conditions — and members get Swim Mapper, Catch Logger and Trip Planner. It's the only US map with a dedicated carp-water layer.
