Voluntary Agreement Highlights Habitat Questions

Restoring marsh and wetland habitat can have significant benefits for dozens of species throughout the Bay and Delta—that’s beyond dispute. But when it comes to saving the Estuary’s most imperiled fish, how much habitat improvements can help in the absence of dramatically increased freshwater flows is a question that has dogged and divided scientists and policy makers for years. As the State Water Resources Control Board considers the latest proposal from the State and water agencies for a flows agreement that would restore thousands of riparian and wetland acres—while dedicating less water to the environment than proposed under an alternative regulatory framework—critics argue that science doesn’t support its underlying assumptions. The debate highlights how much there still is to learn about what restoration efforts can and cannot do for the Delta’s ravaged ecosystem.
