Arrowhead Reservoir is a reservoir in Lemhi County, Idaho and covers about 2.6 acres and holds roughly 16 acre-feet.

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

Fish and Baits

On an overcast morning near a creek-side turn in stained water, the fish mix is not confirmed, so check fresh local information before choosing a target or keeping a catch.

On a bright afternoon near an open-water edge in clear water, 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 a rocky edge with a moving bait, start where two things meet: weeds and open water, rock and mud, a point and a drop, or clear water and dirty water; fish that edge at more than one depth before leaving it.

Season by Season

While using a simple two-depth check near the edge of deeper water before changing areas, 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

During the start of a weather change near a creek-side turn 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 a quiet corner while the water is rising, record the wind, water color, depth of the working lure, 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.
