To date, over 2,500 Spring Chinook have reached Three Mile Falls dam. While Spring Chinook are still entering the river, catching them can be really hard due to high water temperatures this time of year. As a reminder, hatchery steelhead retention closed May 1 and spring Chinook retention closes June 30th.
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.
