Fish species in Sheriff Reservoir

Sheriff Reservoir is a reservoir in Rio Blanco County, Colorado, and covers about 40 acres, reaches about 10.6 feet at its deepest point and holds roughly 987 acre-feet.

Sheriff Reservoir is compact enough to fish slowly, but a change in weeds or bottom can still split it into separate patterns. With little deep water in Sheriff Reservoir, weeds, wind, and water color can matter more than depth alone.

Fish and Baits

Fish listed for Sheriff Reservoir include Brown Trout, Cutthroat Trout, and Rainbow Trout.

On the 40-acre reservoir in Rio Blanco County, try this for brown trout: work a small minnow bait, spoon, or streamer along cool breaks and moving water.

How to Read the Water

On the 40-acre reservoir in Rio Blanco County, make one shallow pass and one deeper pass on the same shoreline; that shows whether fish are tight to cover or using the first break.

Season by Season

On the 40-acre reservoir in Rio Blanco County, 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.

A Simple Tackle Plan

On the 40-acre reservoir in Rio Blanco County, 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.

During a slow pass across this small, shallow reservoir in Rio Blanco County, 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.
