			 Base flow hydrographs, as represented in Figure 1 in the document entitled
			 "water resources management program, Methow River basin" dated 1976, shall be

			 WAC 173-548-020(2) and 173-548-030.
(4) All rights hereafter established shall be
			 subject to the base flows established in WAC
			 173-548-020(1) through
			 (3), except as provided under WAC
			 173-548-030 herein.
(5) Future appropriations of water which
			 would conflict with base flows shall be authorized, by the director, only in
			 those situations when it is clear that overriding considerations of the public
			 interest will be served.
