Lower Thumb Reservoir is a reservoir in Minidoka County, Idaho.
No reliable acreage is listed for Lower Thumb Reservoir, so begin with visible cover and the first clear change in depth.
On a calm morning near a small drop near firm bottom, the fish mix is not confirmed, so check fresh local information before choosing a target or keeping a catch.
During the start of a weather change near a firm-bottom flat before changing depth, 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.
On a low-light period near a protected point after warm rain, 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.
While using a short pass along useful shoreline near a narrow cove while the water is rising, 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.
On a calm morning near a windblown shore 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 cool spring morning near scattered wood beside useful cover, 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.
