We respectfully disagree with your Aug. 24 editorial, “Water Board: Vote ‘No’ on Billion-dollar Delta Tunnels project,” which was based on erroneous rhetoric and incorrect information. We depend on water imported from Northern California through the Delta for about 30 percent of the supplies we use in the Southland. But that system is aging and less reliable than it should be. We need an updated, modernized and cost-effective water system, and we need it to protect the Delta environment. Scientists tell us California WaterFix, with its new intakes, twin tunnels, and environmental safeguards will help achieve those goals.
