Asimus Reservoir in Holt County: How and When to Fish It

• Overview

  Look for Asimus Reservoir in Holt County, Nebraska. The bank is 1,677 feet above sea level. About 5 acres of surface, which puts the far bank inside easy sight. Our Holt County list holds plenty of bigger water. Some 17 miles away sits O'Neill, the nearest settlement. Further out sit Atkinson (26 miles) and Wagner (29 miles). No boundary runs near, so the county rules hold throughout.

• Where to Fish on Asimus Reservoir

  Without a survey to go on, judge depth from how the bank falls away. Levels move with the draw rather than the rain on water like this. Points where the flooded channel swings in are the reliable ones. Across Holt County, recorded fish include common carp, green sunfish, white sucker, brown trout and redfin pickerel. These are county-wide records, so not all of them will be in this water. Asimus Reservoir gives up more to patience than to distance.

• Seasonal Patterns

  July is the warm end of the year here, averaging about 76°F, while January sits near 20°F. Seasons are distinct, and each one fishes differently. Hard water holds through the cold months, breaking up near late March. On average, late March opens the water and early December closes it again. June through September is the settled part of the year, with the shoulders busier for fish. Time your trip to Asimus Reservoir by conditions rather than dates.

• Tackle & Baits

  Access is not recorded for this water. Nothing is listed nearby for parking or launching a boat. For the trout, small spinners and a box of nymphs cover both approaches. Local rules can differ across the county line, so check where you stand. Where the way in crosses private ground, ask first. The nearest alternative is Becker Reservoir Number 2, 1.8 miles out. Treat Asimus Reservoir as unsettled until someone local tells you otherwise.
