Washington Administrative Code › Title 173 - Ecology, Department of (See also Titles 197, 317, 372, and 508) › Chapter 173-591 - Reservation of future public water supply for Thurston County › Section 173-591-070 - Reservation

Current through Register Vol. 24-14, July 15, 2024
(1) The department,
			 having received a final environmental impact statement dated January 16, 1985,
			 and having conducted an investigation of the surrounding impacts of the
			 proposed reservation and having heard comments solicited through the notice of
			 receipt of petition and having found groundwaters to be generally available for
			 the purposes of the reservation and that the proposed use of the groundwaters
			 will result in the maximum net benefit for the people of the state, does hereby
			 reserve portions of those groundwaters for future public water supplies in
			 Thurston County.
(2) The department
			 finds that to provide peaking capacity on a daily basis the appropriate amount
			 of the reservation shall be 40,589 gallons per minute, limited to a maximum
			 annual withdrawal of 22,931 acre-feet/year, provided that the total annual
			 withdrawal and diversion from all sources shall not exceed 48,225
			 acre-feet/year. This is intended to serve the estimated population of 288,092
			 in fifty years. The amount of this reservation shall be reviewed by the
			 department whenever new information, changing conditions, or statutory
			 modifications make it necessary to consider revisions.
(3) A map showing the reservation area
			 boundary is shown in Figure II-1 of the coordinated water system plan for
			 Thurston County, dated May 1982, as approved by the department of social and
			 health services for the purposes of reserving water for future public water
			 supply purposes, and shown as the reservation area boundary map in WAC
			 173-591-130, Illus. 1.
(4) Due to the nature of the geographic
			 distribution of the groundwaters to be reserved and the development patterns
			 that are anticipated in Thurston County, the reserved groundwaters are intended
			 to be beneficially utilized from the unconsolidated materials overlying
			 bedrock, and are prorated to the subareas designated in Figure V-1 of the
			 coordinated water system plan for Thurston County, dated May 1982, as approved
			 by the department of social and health services for the purpose of reserving
			 water for future public water supply purposes, and shown as the reservation
			 source of supply subareas map in WAC
			 173-591-130, Illus. 2. The
			 reserved groundwaters are generally prorated to the reservation source of
			 supply subareas as follows, with the totaled reserved quantity to be obtained
			 from within the boundary area.
