California water officials on Friday released a plan to increase flows through a major central California river, an effort that would save salmon and other fish but deliver less water to farmers in the state’s agricultural heartland. It’s the latest development in California’s long-running feud between environmental and agricultural interests and is likely to spark lawsuits. “The State Water Resources Control Board’s decision today is the first shot fired in the next chapter of California’s water wars,” warned Democratic Assemblyman Adam Gray of Merced, who represents San Joaquin Valley communities that rely on diversion from the river for water supply.
