Regulators agreed to yet more workshops to attempt to resolve when and how to go forward with setting flows for the Bay-Delta, which can impact upstream hydropower. During a Feb. 21 informational hearing on how to integrate the various proceedings and reports to alleviate the struggling Delta ecosystem and avoid significant impacts to water supplies, the State Water Resources Control Board agreed to postpone updating flow standards for the Sacramento and San Joaquin rivers, which house hundreds of hydropower dams. Conservationists and commercial and recreational fishing groups cried foul after the board said it would hold more workshops as urged by water agencies and public power agencies. How to balance ecosystem needs and water export demands from the heart of the state\u2019s water system, which also is a major estuary, has been vigorously debated for decades and been the subject of countless meetings, workshops, and legal challenges. \u201cAdaptive management is not new and the Salmon have been doing it for decades. It is called population decline,\u201d warned Victor Ganella, Golden Gate Salmon Association president.
