In a stopgap measure to help struggling spring- and winter-run Chinook salmon spawn in the face of rising water temperatures and lower water levels due to climate change, state and federal wildlife officials in Northern California have begun trucking adult fish to cooler waters.
The spring- and winter-run salmon are genetically different, with the seasonal labels marking when adult fish travel from the Pacific Ocean back to the Sacramento River to spawn.
The spring-run Chinook, listed as threatened under the Endangered Species Act, are being moved from traps at the base of Keswick Dam to Clear Creek in the Sacramento River.
