Fish species in Big 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.

Big Lake in Custer County is a reservoir in Idaho.

Use the shape you can see at Big Lake: check the best cover, the first drop, and one open-water line before moving.

Fish and Baits

Fish listed for Big Lake include Cutbow Trout, Cutthroat Trout, and Rainbow Trout.

On a cool spring morning near the first break under flat light, cast a small spoon, inline spinner, light jig, or fly through cool water for rainbow trout.

Cutthroat Trout, Rainbow Trout, Tiger Trout, and Yellowstone 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

On a slow shoreline pass near a windblown shore near firm bottom, do not let the deepest number control the whole day; nearby cover, firm bottom, and food usually matter more than the deepest hole by itself.

Season by Season

While using a brief open-water pass near an open-water edge close to shade, early in the year, protected water and the first warm afternoon can be the best clues; as the water heats up, check deeper edges without assuming every fish is on the bottom; cooling fall water often makes points and firm banks useful again.

A Simple Tackle Plan

On a slow shoreline pass near a quiet corner after a cold night, 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 cool spring morning near a narrow cove in clear water, record the wind, water color, depth where the bait worked, 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.
