Major California River Adding Key Ingredient: Water

A decade ago, environmentalists and the federal government agreed to revive a 150-mile stretch of California’s second-longest river, an ambitious effort aimed at allowing salmon again to swim up to the Sierra Nevada foothills to spawn. A major milestone is expected by the end of the month, when the U.S. Bureau of Reclamation says the stretch of the San Joaquin River will be flowing year-round for the first time in more than 60 years. But the goal of restoring native salmon remains far out of reach. The original plan was to complete the task in 2012.
