Trefz Reservoir is a reservoir in Kootenai County, Idaho and covers about 13 acres and holds roughly 9 acre-feet.

On a water as small as Trefz Reservoir, one weed edge or deeper pocket can hold much of the day’s activity.

Fish and Baits

On a low-light period near a shallow shelf close to shade, the fish mix is not confirmed, so check fresh local information before choosing a target or keeping a catch.

On a methodical search near a quiet corner while the water is falling, 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

During the first pass near an open-water edge while the water is rising, 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 short pass along useful shoreline near the first break with light wind, 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 an overcast morning near a channel bend with light wind, 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 return to the best bank near scattered wood close to shade, record the wind, water color, depth of the best pass, 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.
