Fish species in Zumwalt 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.

Zumwalt Lake is a lake in Boise County, Idaho.

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

Fish and Baits

Fish listed for Zumwalt Lake include Rainbow Trout.

On a quick scouting pass near the first break before changing depth, cast a small spoon, inline spinner, light jig, or fly through cool water for rainbow trout.

On a short evening pass near a shallow shelf while the water is falling, 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

On a warm summer afternoon near a narrow cove before changing areas, 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 simple two-depth check near a rocky edge with a slow lure, 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

During the first hour near an open-water edge with light wind, 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 steady fall day near a narrow cove before changing depth, record the wind, water color, depth of the working lure, 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.
