Upper Rainbow Lake is a lake in Idaho County, Idaho and covers about 2.34 acres.

Upper Rainbow Lake is small water, so a careful lap around the bank can show most of the useful cover.

Fish and Baits

On a quick scouting pass near a soft-to-hard bottom change where two features meet, the fish mix is not confirmed, so check fresh local information before choosing a target or keeping a catch.

On a steady fall day near a clean gravel patch away from empty shoreline, 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 steady fall day near the first break in clear water, 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 short pass along useful shoreline near a small drop close to shade, 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 check of nearby water near a small drop in stained water, 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 check of nearby water near the edge of deeper water after warm rain, 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.
