Fishing has been good on the lower Umatilla River. While Chinook retention recently closed below Three Mile Falls Dam, coho and steelhead are being caught in good numbers. Anglers can expect to find fish throughout the river, although the best action will likely continue to occur below Three Mile Falls Dam.
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. Targeting bull trout is NOT allowed in the Umatilla River.
