Colossal Reservoir is a reservoir in Malheur County, Oregon.
No reliable acreage is listed for Colossal Reservoir, so begin with visible cover and the first clear change in depth.
Fish listed for Colossal Reservoir include Bluegill, Brown Bullhead, Largemouth Bass, Redside Shiner, and Rainbow Trout.
During a slow shoreline pass near the mouth of a pocket with light wind, use a small jig, worm, or tiny plastic around green weeds and protected pockets for bluegill.
During a warm summer afternoon near a creek-side turn with a slow lure, work a soft plastic, jig, or spinnerbait around weeds and protected cover for largemouth bass.
During a slow shoreline pass near an open-water edge with a slow lure, use a worm on the bottom in a warm, quiet pocket during low light for brown bullhead.
During a slow shoreline pass near a small drop near visible bait, cast a small spoon, inline spinner, light jig, or fly through cool water for rainbow trout.
During a check of nearby water near the outside weed line in stained water, 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.
Later in the trip, spring fishing starts 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.
During an overcast morning near a quiet corner after a cold night, a light spinning rod, thin line, a few small spoons, inline spinners, and jigs cover the listed trout; carry one slightly heavier setup when other fish or windy water call for more control.
During the final pass near the outside weed line with stable weather, record the wind, water color, water depth at the strike, 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.
