Wyoming Fishing Reports

Wyoming means trout at scale: the North Platte's Grey Reef tailwater grows rainbows like a hatchery with rapids, the Bighorn and Wind River systems add canyon water, and the high country holds golden trout lakes that require boots and ambition. Uncrowded is the default.

Fishing Wyoming: the long view

The Platte system

Grey Reef is the headline: stable dam flows and endless scud beds produce 16-20 inch rainbows in absurd density, floated with rubber-legs and worms year-round. Upstream, the Miracle Mile between Kortes and Pathfinder offers bigger water and migratory browns; downstream, Fremont Canyon's pocket fishing rewards climbers. Casper has quietly become a fly-fishing town.

Beyond the Reef

The Wind River Range hides golden trout above 10,000 feet (a backpacking grail), the Snake's fine-spotted cutthroat define Jackson Hole, and Flaming Gorge's Wyoming arm holds lake trout of stunning size. Winter fishing continues on the tailwaters: 20-fish January days at the Reef surprise no local.

About fishing in Wyoming

When should I float Grey Reef?

It fishes year-round: April-May (pre-runoff) and October are prime, the famous "worm bite" follows spring flushing flows, and even January produces. Book shuttles in Casper or Alcova.
