Leaping over small man-made jumps and swimming determinedly upstream in Alameda Creek, a small group of bright red chinook salmon are back from the Pacific Ocean and ready to spawn. … Once native to the stream, chinook salmon have been unable to reach the upper portion of Alameda Creek for decades due to concrete barriers and other water supply infrastructure blocking their path. … But over the past three decades, the Alameda County water and flood control districts and other agencies — urged on by environmental groups — have completed restoration projects meant to encourage fish migration.
