Washington Administrative Code › Title 173 - Ecology, Department of (See also Titles 197, 317, 372, and 508) › Chapter 173-518 - Water resources management program for the dungeness portion of the Elwha-Dungeness water resource inventory area (WRIA) 18 › Section 173-518-040 - Establishment of instream flows

Current through Register Vol. 24-14, July 15, 2024
(1) The
			 instream flows established in this section are based on recommendations in the
			 2005 Elwha-Dungeness watershed plan, consultation with the Jamestown S'Klallam
			 Tribe, the departments of fish and wildlife, agriculture, and commerce; and
			 public input received during the rule-making process.
(2) Instream flows established in this rule
			 are necessary to meet the water resource management objectives of the
			 Elwha-Dungeness watershed plan.
(3)
			 Instream flows established in this rule are water rights and will be protected
			 from impairment by any new water rights commenced after the effective date of
			 this chapter and by future water right changes and transfers.
(4) Instream flows are expressed in cubic
			 feet per second (cfs), and are measured at the control stations identified in
			 Table I. Tables II A and B identify instream flows set by this rule.
(5) Exceptions to the instream flow
			 requirements are provided in WAC
			 173-518-070,
			 173-518-080, and
			 173-518-085. Any other new water
			 appropriation established after the effective date of this rule will be subject
			 to interruption when stream flows drop below the instream flow levels set in
			 Table II.
