Steelhead can be found throughout the Umatilla River, although fishing on the lower section near the 730 Br has been the best. Anglers have reported that their catch has been predominately composed of unclipped fish, with most fish being caught on jigs under a float.

There is now a new regulation in place with a hook gap size that may not exceed 3/8 inch in the section of the Umatilla River above the CTUIR reservation. This new regulation is to protect bull trout and decrease the chance of hooking mortality. As a reminder, if you catch a bull trout, recognized by its white spots, please keep it in the water and release it as quickly as possible. No targeting of bull trout is allowed in the Umatilla River.
