Johnson Reservoir in Boundary County is a reservoir in Idaho and covers about 1 acres and holds roughly 3.1 acre-feet.

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

Fish and Baits

On a slow shoreline pass near a channel bend while the water is falling, 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 the outside weed line with stable weather, 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 quick scouting pass near a shaded bank 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 pass along the first break near a shaded bank with a moving bait, 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 calm morning near an open-water edge while the water is falling, 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 warm summer afternoon near the edge of deeper water after warm rain, record the wind, water color, depth where fish were holding, 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.
