North Platte River, WY Fishing Report & Live Conditions

North Platte River, WY fishing report

Grey Reef is primarily a tailwater trout fishery — big rainbows and browns are the main draw, with fish stacking below the dam where cold, consistent releases create ideal year-round conditions. Spring runoff can cloud flows and push fish tight to slower edges, while summer low flows concentrate trout in defined seams and troughs. As water cools into fall, browns move aggressively during the spawn. Honest truth: largemouth, smallmouth, walleye, chain pickerel, catfish, and panfish are not part of this tailwater ecosystem — Grey Reef is trout water, and that's what you're here for.

Wade the broken water where fast current meets slower pockets — trout hold in those transition zones. Small midge and BWO patterns under an indicator produce consistently, and streamers swung through deeper runs move larger fish, especially in lower light. Watch your thermometer: water temps in the low-to-mid 50s put trout actively feeding throughout the column. When flows climb above comfortable wading levels, nymph the softer inside bends. Size down your tippet in clear low-flow conditions — fish here are pressured and leader-shy.
