The Delta Tunnel would be a proposed new 6,000 cubic feet-per-second (cfs) diversion from the Bay Delta. The Delta is the West Coast's largest estuary and where many of California's large rivers flow into. The Bay Delta feeds the San Francisco Bay and it feeds many cities drinking water supplies. The Bay and Delta, and all the watersheds that feed them are currently facing toxic algae blooms, fish kills and even fisheries extinctions.
 
The Delta Tunnel would harm the Delta, Bay, and tributaries. The proposed project would include two intakes with a maximum diversion capacity of about 3,000 cfs each. Each intake location could range from 75 to 150 acres and are located in areas that are culturally significant to Delta Tribes. This tunnel could impact the San Joaquin, Trinity and Sacramento River watersheds and could drain our NorCal reservoirs and rivers. The tunnel is also linked to the proposed 14,000 acre Sites Reservoir. Together these projects could move much of Northern California's water to water brokers in Southern California. Recently the Tunnel Draft Environmental Impact Report (DEIR) was released and public comment is open.
