Fish species in Big Boulder Reservoir

Big Boulder Reservoir is a reservoir in Harney County, Oregon.

No reliable acreage is listed for Big Boulder Reservoir, so begin with visible cover and the first clear change in depth.

Fish and Baits

Fish listed for Big Boulder Reservoir include Bluegill, Brown Bullhead, Largemouth Bass, Redside Shiner, and Rainbow Trout.

During a methodical search near a narrow cove near visible bait, use a small jig, worm, or tiny plastic around green weeds and protected pockets for bluegill.

During the last hour of daylight near a channel bend beside useful cover, work a soft plastic, jig, or spinnerbait around weeds and protected cover for largemouth bass.

During a cool spring morning near the edge of deeper water where two features meet, use a worm on the bottom in a warm, quiet pocket during low light for brown bullhead.

During a quick scouting pass near a creek-side turn where food is present, cast a small spoon, inline spinner, light jig, or fly through cool water for rainbow trout.

How to Read the Water

During a careful second pass near a quiet corner 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

During a quick scouting pass near a channel bend with light wind, 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.

A Simple Tackle Plan

During a check of nearby water near scattered wood before changing areas, 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 a slow shoreline pass near the edge of deeper water near firm bottom, 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.
