Johnson Lake in Granite County is a lake in Montana.

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

Fish and Baits

Around the lower edge of an inlet turn, the fish mix here is not confirmed, so check fresh local information before choosing a target or keeping a catch.

Beside the lower edge of the nearest cove, 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

Near the firm edge of a firm-bottom hump, 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

Along the steep side of an outside bend, 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

Near the sunny side of a broad flat, 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.

Around the current seam of a patch of green weeds, record the wind, water color, depth where fish bit, 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.
