OREGON CITY — Sea lions will be hazed daily during February, March and April from Willamette Falls to the Interstate 205 Bridge to reduce predation on spring chinook salmon.

The Oregon Department of Fish and Wildlife announced today that hazing will begin on Feb. 4 during daylight hours on the mile between the fish ladders at Willamette Falls and the bridge.

The hazing crew will use specially designed fireworks from the fish ladder and from a boat to move California sea lions away from where salmon and steelhead congregate before entering the ladders.

The Oregon Legislature mandated the hazing through passage of House Bill 3255 in 2011. The hazing in done according to provisions of the Marine Mammal Protection Act with authorization from the National Marine Fisheries Service.

Hazing of sea lions at Bonneville Dam is scheduled to begin in March and continue until mid-May.
