Minersville Reservoir - Adamsville, Utah

Minersville Reservoir is a standout trout fishery in southern Utah, known for producing large rainbows and occasional trophy browns. Located near Adamsville, this 990-acre lake offers year-round access, excellent shoreline facilities, and a reputation for quality over quantity.

Trout over 20 inches are common, with many caught on flies, spoons, or shallow-diving plugs. Fly anglers use streamers, midges, and leeches, particularly in spring and fall. Spin fishing with Rapalas and Kastmasters is productive along drop-offs and points.

Special regulations are in place to encourage larger fish. Bait is restricted, and anglers must use artificial flies or lures. Slot limits apply—always consult the current Utah Fishing Guidebook before heading out.

Spring and fall are the most productive seasons, with cooler water and active trout. Ice fishing is possible in winter, particularly near the dam.

Minersville has a concrete boat ramp, primitive camping, and bank access. The lake is wind-prone, so early mornings and evenings are often best.

For anglers seeking a shot at trophy trout in a manageable setting with relatively light pressure, Minersville delivers. Its special rules and quality fish management make it a premier destination in the region.
