Re "If BDCP were science-based, Delta flows would be a priority" (Editorials, May 12): Recently, The Bee asked Gov. Jerry Brown to halt plans to build a new way to divert water from the Delta until "there is a clear understanding among all parties" on how Delta flows should be divided between environmental and human uses.
Missing is this important point from a recent Public Policy Institute of California report: "Although scientific understanding of the ecosystem has vastly improved, the Delta's complexity makes uncertainty inevitable."
Brown's Bay Delta Conservation Plan embraces that inevitable uncertainty with applied science and robust monitoring to determine spring and fall Delta outflows, and the feedback loop of adaptive management to ensure that water project operations do not interfere with the recovery of native fish populations.
That is a far surer path to clear understanding of Delta flows than doing nothing, which would risk species extinction and water supplies for much of California.
