Proposed Additional Environmental Water Demands for Cases I through III envelop potential and uncertain demands and have immediate and future consequences on supplies from the Delta, beginning with actions in 1992 and 1993 to protect winter-run chinook salmon and delta smelt (actions which could also protect other fish species).
Surface Water and Ground Water Overdraft: The degree future shortages are met by increased overdraft is unknown. Since overdraft is not sustainable, it is not included as a future supply.
Level 1 Water Management Programs: Protection of fish and wildlife and a long- term solution to complex Delta problems will determine the feasibility of several water supply augmentation proposals and their water supply benefits.
