Big Boulder Lakes is a lake in Custer County, Idaho.

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

Fish and Baits

On a quick scouting pass near a small drop in stained water, the fish mix is not confirmed, so check fresh local information before choosing a target or keeping a catch.

On a short evening pass near a creek-side turn with a moving bait, 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 warm summer afternoon near a creek-side turn 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 one pass along the first break near a soft-to-hard bottom change away from empty shoreline, 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 methodical search near a quiet corner in clear 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 quick scouting pass near a quiet corner where food is present, record the wind, water color, depth of the first bite, 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.
