(May 28, 2015, Associated Press)
Electrified mats didn't work. Neither did chicken wire or colored flagging tape. The City of Astoria, Oregon, near the entrance to the Columbia River hopes beach balls will do the trick to keep thousands of sea lions from using the city docks.

NOAA APPROVES REMOVAL OF SEA LIONS AT BONNEVILLE DAM
(May 15, 2011, Associated Press)
Oregon and Washington have been given permission to resume removing or killing California sea lions at Bonneville Dam on the Columbia River, a federal agency said Friday.
SEA LIONS FEED ON STURGEON AT BONNEVILLE DAM
(February 26, 2011)
Oregon and Washington fishery agencies petitioned to remove Steller sea lions from federal protection - it is listed as "threatened" under the Endangered Species Act. Key to that is to count how many salmon, steelhead and sturgeon the Stellers take.
The decline led Oregon and Washington this month to put the tightest limits ever on sport and commercial sturgeon fishing, the fourth straight year of cuts. While the states are about to adopt a conservation plan, most biologists and fishermen fear a continued decline of sturgeon, and an eventual halt to all sport and commercial fishing.

SEA LIONS CONTINUE TO MUNCH SALMON, DESPITE HAZING AND LETHAL INJECTION PROGRAM
(May 13, 2010)
Despite hazing by shotgun-fired firecrackers, rubber buckshot and lethal injections that have killed 10 California sea lion this year, the amount of salmon eaten by sea lions at Bonneville Dam is approaching record levels. Animal activists say the numbers prove that the offensive is futile.
SEA LIONS KILLED FOR EATING SALMON
(March 8, 2010, Huffington Post)
A California sea lion last week became the first salmon predator to be euthanized this year under a program that has been denounced by those who say there are far greater dangers to salmon – including the series of hydroelectric dams on the Columbia river. Read the full story.
SWIMMING IN CONTROVERSY, SEA LION C265 IS FIRST TO BE KILLED
(April 17, 2009, The Oregonian)
Last month, "C265" became the first Californina sea lion legally euthanized by the government since the marine mammal protection act passed nearly 40 years ago. Read the story of why this sea lion, who ate approximately 43 salmon in one year out of roughly 85,000 which passed through the fish ladder at Bonneville Dam, was killed.
FIRST SALMON-EATING SEA LION KILLED AT BONNEVILLE DAM
(March 12, 2009, The Oregonian)
Wildlife officials euthanized a salmon-eating sea lion at Bonneville Dam for the first time Thursday, killing it with a lethal injection after a health examination determined it couldn't be relocated to a zoo or aquarium. The California sea lion -- branded C265 -- is thought to be the first deliberately killed by a Northwest government agency. Marine mammals received legal protection under the Marine Mammal Protection Act of 1972
JUDGE OKAYS PLAN TO KILL SEA LIONS AT BONNEVILLE DAM
(November 26, 2008)
A federal judge says state governments can proceed with plans to kill up to 85 California sea lions a year for five years in the Columbia River at Bonneville Dam.
