Lower Columbia below Bonneville Dam - Now closed to fishing for salmonids. Through April 15, an estimated 75,282 angler trips produced 6,142 chinook kept and 1,326 released from the I-5 Bridge downstream. Last week we sampled 2,823 salmonid anglers (including 1,140 boats) with 653 adult and 4 jack chinook and 3 steelhead. Including fish released, boat anglers averaged an adult chinook per every 4.1 rods while bank anglers averaged one per every 19.3 rods based on mainly complete and incomplete trips, respectively. Boat anglers from Woodland downstream had the highest success rates. 561 (85.9%) of the 653 adult chinook caught were kept. 330 (60.3%) of the 547 fish sampled were upriver stock based on Visual Stock Identification. I-5 Bridge downstream to the Rocky Point/Tongue Point line will re-open for hatchery steelhead and hatchery chinook jacks beginning May 16. Any chinook, with or without an adipose fin, may be retained from Bonneville Dam downstream to the Rocky Point/Tongue line beginning June 16. Adult chinook must be released in July. Shad angling re-opens May 16 from Bonneville Dam downstream. Bonneville Pool - Light effort and no catch observed.
