Felicia Marcus, a member of the California State Water Resources Control Board, talks about the governance of the Sacramento-San Joaquin Delta and why she is optimistic on warring water interest reaching a compromise on the management of the estuary as both a major ecosystem and heart of the state's water delivery system. Marcus says the five-member board is at a critical juncture in California's water history. "The next four years will see a series of decisions that have the promise of both improving public health protection and of meeting the 'co-equal' goals of water supply reliability and ecosystem protection (in the Delta)," she said last August in a news release on the Senate confirmation of her board appointment, by Gov. Jerry Brown. "The state board will either make or be a critical player in those decisions."
