The Metolius River continues to be excellent for mountain whitefish, redband trout, and bull trout. Bull Trout number are increasing in the river as they begin the spawning migration from Lake Billy Chinook. Nymphing with golden stonefly, mayfly or caddisfly nymphs has been effective for trout and streamers are a good bet for bull trout. Anglers should keep an eye out for afternoon pale morning dun and caddis hatches.

Catch-and-release for trout including bull trout. Fishing is restricted to fly-fishing only upstream of Bridge 99 (Lower Bridge).

The Metolius River from Allingham Bridge upstream to the headwaters reopened for the season May 22, 2025.

Artificial flies and lures permitted below Bridge 99 (Lower Bridge).
