Jim Larson Reservoir

Jim Larson Reservoir is a reservoir in Wayne County, Utah and covers about 1.5 acres, reaches about 11.2 feet at its deepest point and holds roughly 7.1 acre-feet.

One weed edge or deeper pocket can hold much of the day’s activity; fish the first useful drop, then match the hook and line to the named target. With little deep water in Jim Larson Reservoir, weeds, wind, and water color can matter more than depth alone.

Fish and Baits

Fish listed for Jim Larson Reservoir include Rainbow Trout.

To begin with rainbow trout on Jim Larson Reservoir, cast a small spoon, inline spinner, light jig, or fly through cool water.

How to Read the Water

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; work the best shade during bright hours, then give low-light water a slower bottom pass.

Season by Season

In spring, start with warming banks, creek mouths, and shallow cover; summer usually pushes the better bite toward the outside weed edge or a nearby drop; fall can bring bait back to windblown points, while winter calls for smaller moves and a slower pace; check the coolest inflow, then use a smaller lure in clear water.

A Simple Tackle Plan

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; start with the cover closest to deep water, then use the old channel as a guide.

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; begin over firm bottom, then add vibration in stained water.
