Fish species in Upper Trilby Lake

Official stocking history

Stocking records show that the following fish or strains were stocked here. A historical stocking does not by itself prove that a self-sustaining population remains today.

Upper Trilby Lake is a lake in Idaho County, Idaho.

No reliable acreage is listed for Upper Trilby Lake, so begin with visible cover and the first clear change in depth.

Fish and Baits

Fish listed for Upper Trilby Lake include Westslope Cutthroat Trout.

On a quick scouting pass near a rocky edge with stable weather, Cutthroat Trout, Rainbow Trout, and Westslope Cutthroat Trout have also been stocked here; that proves fish were released, but it does not promise that they are still common or easy to catch.

How to Read the Water

During the final pass near a firm-bottom flat after a cold night, use wind as a clue; a light push can carry food toward a bank, but hard wind may muddy it, so look for a clean edge near a point or protected pocket.

Season by Season

While using a short check of nearby structure near a shallow shelf with stable weather, spring runoff can add color and pull fish toward fresh water; green weeds and the first drop become stronger summer targets; in fall, follow bait toward points and shallow flats, while winter rewards a slower search.

A Simple Tackle Plan

On a cold winter outing near a quiet corner beside useful cover, 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.

On a slow shoreline pass near the first break where food is present, record the wind, water color, depth of the first bite, 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.
