	Values may not be identical to those reported or published by the water management district due to differences in data-collection procedures, categories of use, or revisions in reported or published values.
	Power generation withdrawals for 1991 through1994 and 1996 through 1999 do not include all once-through cooling water withdrawn at several plants within the district (shown in italic).
	Power generation withdrawals for 2001 through 2004 are included in the commercial-industrial-mining category, however, they do not include all of the once-through cooling water withdrawn within the district.
	Public supply treated includes water that does not meet public drinking water standards and is either treated through a desalination process or diluted with fresher water to meet standards.
	The procedure used to estimate domestic self-supplied withdrawals changed for 2000 from previous years as a different per capita used to calculate withdrawals.
	Agricultural includes water withdrawn for crop irrigation, livestock, and fish farming purposes.
	Recreational irrigation includes water used for all turf grass (golf, commercial, industrial, and public) irrigation. This category was accounted for under Agricultural from 1975 through 1984.
