C-WIN is a statewide nonprofit dedicated to equitable and sustainable use of California's water resources. Both our Board and Staff members provide the environmental community support and leadership on enforcement of the state's Bay-Delta public trust responsibility, on stopping irrigation of naturally contaminated farm lands in the San Joaquin Valley, and on the speculative water practices of federal and state water projects in California. We educate the public about public trust resource and California's constitutional prohibition of waste and unreasonable use of water, and about alternatives that restore rivers, fisheries, and other public trust resources.

The Partnership for the Delaware Estuary, a National Estuary Program, leads science-based and collaborative efforts to improve the tidal Delaware River and Bay, which spans Delaware, New Jersey, and Pennsylvania.
