Salmon that spawn in the Sacramento River in the Redding area are enduring the lowest survival rate on record this year. About 149,000 young winter-run chinook salmon have made it from Redding to Red Bluff this year on their annual trek to the Pacific Ocean, according to data from the University of Washington’s School of Aquatic and Fishery Sciences. In an average year, about 1.3 million of the winter-run salmon would be counted near the former Red Bluff Diversion Dam. This is the second-straight year the number of winter-run salmon migrating down the Sacramento River to the ocean has been very low, according to the National Oceanic and Atmospheric Administration. Last year, only 557,652 young salmon got as far as Red Bluff.
