From The Columbian:
Washington and Oregon wildlife officials will resume their annual campaign to trap and euthanize salmon-munching sea lions at Bonneville Dam as soon as this week.

It could be a target-rich environment.

With a giant run of spring chinook salmon projected, California sea lions are likely to soon begin congregating en masse at the man-made bottleneck created by the dam. Four floating traps have been hauled into place on an island below the Washington-side powerhouse, and state officials said they expect to begin trapping animals sometime this week.

“Business as usual,” said Rick Hargrave, a spokesman for the Oregon Department of Fish and Wildlife.
