August 28, 2020 — Up to 716 sea lions may be removed from a Columbia River management zone over the next five years to reduce the animals’ impact on salmon and steelhead populations, under a new federal authorization granted to states and tribes in the U.S. Northwest.
In 2018, the U.S. Congress amended the Marine Mammal Protection Act to allow removal of sea lions from a stretch of the Columbia River between the I-205 bridge on Portland’s east side and McNary Dam. The change also allowed for removing sea lions from Columbia River tributaries below the McNary Dam that are spawning habitat for threatened or endangered salmon and steelhead runs.
