Thorson Reservoir is a reservoir in Idaho County, Idaho and covers about 1 acres and holds roughly 7 acre-feet.

Thorson Reservoir is small water, so a careful lap around the bank can show most of the useful cover.

Fish and Baits

During the first hour near scattered wood in stained water, the fish mix is not confirmed, so check fresh local information before choosing a target or keeping a catch.

On a slow shoreline pass near a shaded bank with a slow lure, begin with one slow bottom presentation and one moving bait, then let bites show whether fish are holding close to cover or roaming open water.

How to Read the Water

On a careful second pass near a narrow cove in clear water, 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 one careful route near the downwind side with stable weather, 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 a low-light period near a creek-side turn where two features meet, a medium spinning rod, 8-pound line, a small box of jigs, a few crankbaits, and a simple bottom rig cover most situations; change depth or speed before changing every piece of tackle.

On a methodical search near a firm-bottom flat close to shade, record the wind, water color, depth that produced twice, 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.
