Presents environmental impacts of the Delta Wetlands Project, which would increase availability of high-quality water in the Sacramento-San Joaquin River Delta for export or outflow through its six basic parts, including: diversion of water in the Delta, water storage on two reservoir islands; compensation for wetland and wildlife effects of the water storage operations on two reservoir islands; supplemental water storage in the Semitropic Groundwater Storage Bank and the Antelope Valley Water Bank south of the Delta; provision for water supply for south of Delta users; and release of water for water quality enhancement in the Bay-Delta Estuary in the fall.
