March 22nd, 2024
urvival of Columbia River basin salmon and steelhead is poor – in most cases less than 2 percent smolt to adult returns – compared to a Northwest Power and Conservation SARs goal of 6 percent, according to a presentation at the Council’s March meeting.
Strong, Ocean-Warming El Nino Has Arrived But Researchers Say California Current Ecosystem Should Hold Up Better Than Last Time (2015)
March 22nd, 2024
The California Current ecosystem is a vital ocean system stretching from Washington to Baja California. It is facing a strong 2024 El Niño event, a cyclical warming of the Pacific Ocean. However, the latest information from NOAA’s Integrated Ecosystem Assessment program suggests the ecosystem is better positioned to weather these changing conditions than previous El Niño events.

Reopening Rivers For Salmon, Steelhead: 10-Year Effort Underway To Remove, Replace Culverts Blocking Fish Passage On Olympic Peninsula
March 7th, 2024
The cold water rivers of Western Washington hold some of the last, best freshwater habitat for salmon and steelhead in the lower 48 states, and despite a warming climate, their high-elevation headwaters are predicted to remain cool enough for salmon and steelhead for at least the next 50 years.
