Gem Lake is a lake in Utah, near Duchesne County.
The 3.3-acre Gem Lake in Duchesne County is a lake in Utah and covers about 3.3 acres, reaches about 9 feet at its deepest point and holds roughly 11.8 acre-feet.
The small size of Gem Lake makes quiet casts and short moves more useful than carrying a pile of tackle. This water is shallow, so weeds, wind, and water color can matter more than depth alone; change retrieve speed before changing lures.
Fish listed for Gem Lake include Brook Trout, Cutthroat Trout, and Rainbow Trout.
When rainbow trout are the target on Gem Lake, cast a small spoon, inline spinner, light jig, or fly through cool water.
At Gem Lake, start where two things meet: weeds and open water, rock and mud, a point and a drop, or clear water and dirty water; fish that edge at more than one depth before leaving it.
Shallow water is worth a careful look in spring and again during fall; bright summer days favor shade, weeds, or deeper breaks; under ice, a small depth change can be more useful than a long move; make short moves after each pass.
A light spinning rod, thin line, a few small spoons, inline spinners, and jigs cover the listed trout; carry one slightly heavier setup when other fish or windy water call for more control; try the strongest cover, then try a brighter bait when the water is dirty.
Record the wind, water color, productive depth, and cover after a bite; those four notes are more useful on the next trip than a long list of spots that did not produce; work a quiet shoreline, then fish the edge from top to bottom.
