Fixing the State Water Project

When the State Water Project was built in the 1960s, the planners intended to carry water to the state and federal pumping plants through a 43-mile canal skirting the eastern edge of the Delta. The canal would carry water from the Sacramento River to the pumping plants at the Delta's southern end. The canal was intended to protect water quality and avoid significant damage to Delta fisheries caused in part by the federal and state pumping plants, which draw water directly from channels in the south Delta.
For cost reasons, the originally proposed canal was not built. Over time, the state has developed a better understanding of the danger to fish of pumping directly from the south Delta. With the current water challenges in California, populations of native fish have reached historically low numbers, and "reverse flows" and pump entrainment are important factors. Nearly 60 years later, California WaterFix has emerged as the 21st century solution that includes a modern, efficient water system that will realize the co-goals of protecting and securing water resources while maintaining a healthy environment.
