In June, two federal agencies gave their blessings to the controversial project to build two water conveyance tunnels under California’s Sacramento-San Joaquin Delta. Environmental groups promptly sounded the alarm that the state’s so-named WaterFix project would not, as its backers claim, solve the matrix of problems plaguing the Delta and the people and creatures relying on it. The existing pumps that export Delta water have drastically upset the balance of the estuary’s ecosystem, causing fish declines and the intrusion of saltwater from San Francisco Bay.
