	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	Agricultural self-supplied includes water withdrawn for crop irrigation, livestock, and fish farming purposes.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 1965 through 1984.
	Power generation withdrawals for 1996-1999 do not include all fresh surface water withdrawn within the County.
