The Walla Walla River is open for trout, and there is good fishing to be had on the south fork. Anglers can find success using a variety of techniques, including fly-fishing with dry flies. Many trout can be found holding in the soft water behind boulders within rapids.‌

As a reminder, there is now a new regulation in place with a hook gap size that may not exceed 3/8 inch in the Walla Walla River. This new regulation is to protect bull trout and decrease the chance of hooking mortality.‌

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 Walla Walla River.
