Official stocking history

Stocking records show that the following fish or strains were stocked here. A historical stocking does not by itself prove that a self-sustaining population remains today.

Dunn Dam is a reservoir in McCone County, Montana and covers about 11.7 acres.

On a water as small as Dunn Dam, one weed edge or deeper pocket can hold much of the day’s activity.

Fish and Baits

Near the open side of a main-lake point, the fish mix here is not confirmed, so check fresh local information before choosing a target or keeping a catch.

Along the outside edge of a short point, 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

Around the rocky lip of a shallow saddle, 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

Across the outside edge of an outside bend, in spring, start with warming banks, creek mouths, and shallow cover; summer usually pushes the better bite toward the outside weed edge or a nearby drop; fall can bring bait back to windblown points, while winter calls for smaller moves and a slower pace.

A Simple Tackle Plan

Around the firm edge of a flooded tree line, 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.

Near the deep side of a short point, 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.
