Antelope Flat Reservoir, near Post, Oregon, is a high desert impoundment recognized for its rainbow trout fishery, with some steelhead also present. The Oregon Department of Fish & Wildlife (ODFW) regularly stocks fingerling rainbow trout, which exhibit impressive growth, often reaching up to 18 inches. While the water is frequently turbid due to phytoplankton and erosion, anglers still report good success.

Optimal fishing often occurs early in the season, when anglers frequently concentrate near the concrete boat ramp and rocky areas. Given the murky conditions, bait fishing with PowerBait or worms, and spin fishing with brightly colored or vibrating lures like inline spinners, are highly effective. Trolling from a boat can also help cover water.

Access to Antelope Flat Reservoir is convenient, featuring a concrete boat ramp and good bank access in key areas. Conservation efforts focus on sustaining the trout fishery through stocking. Anglers must adhere to all ODFW regulations, including bag limits and proper fish handling, to preserve this productive, albeit often turbid, Central Oregon angling destination.
