WAC 173-510-030. Establishment of instream flows

(1) Stream management units and associated control stations are established as follows: STREAM MANAGEMENT UNIT INFORMATION Control Station No. Stream Management Unit Name Control Station by River Mile and Section, Township, and Range Affected Stream Reach(es) 12-0965.00 Upper Puyallup River 12.2 25-20-4E Confluence with Puyallup River to the headwaters including all tributaries 12-0957.00 Carbon River 0.1 13-19-4E From the confluence with the White River to the headwaters including all tributaries, excluding the Carbon River. 12-1015.00 Lower Puyallup River 6.6 20-20N-R4E From the influence of mean annual high tide at low base flow levels to the confluence with the White River including all tributaries and excluding the White River. STREAM MANAGEMENT UNIT INFORMATION Control Station No. Stream Management Unit Name Control Station by River Mile and Section, Township, and Range Affected Stream Reach(es) 12-0965.00 Upper Puyallup River 12.2 25-20-4E Confluence with Puyallup River to the headwaters including all tributaries 12-0957.00 Carbon River 0.1 13-19-4E From the confluence with the White River to the headwaters including all tributaries, excluding the Carbon River. 12-1015.00 Lower Puyallup River 6.6 20-20N-R4E From the influence of mean annual high tide at low base flow levels to the confluence with the White River including all tributaries and excluding the White River. (2) Instream flows are established for the stream management units in WAC 173-510-030(1) as follows: INSTREAM FLOWS IN THE PUYALLUP RIVER BASIN (cubic feet per second) Month Day 12-0965.00 Puyallup River (At Alderton) 12-1015.00 Puyallup River 12-0957.00 Carbon River Jan 1 700 1400 600 15 700 1400 550 Feb 1 750 1400 550 15 800 1500 550 Mar 1 800 1600 550 15 850 1700 550 Apr 1 900 1800 600 15 950 1900 700 May 1 950 2000 900 15 1000 2000 900 Jun 1 1050 2000 600 15 1050 2000 500 Jul 1 1050 2000 450 15 1050 1750 400 Aug 1 900 1500 350 15 800 1300 350 Sep 1 600 1150 350 15 500 1000 350 Oct 1 500 1000 350 15 500 1000 550 Nov 1 600 1000 550 15 700 1100 600 Dec 1 700 1200 700 15 700 1300 700 INSTREAM FLOWS IN THE PUYALLUP RIVER BASIN (cubic feet per second) Month Day 12-0965.00 Puyallup River (At Alderton) 12-1015.00 Puyallup River 12-0957.00 Carbon River Jan 1 700 1400 600 15 700 1400 550 Feb 1 750 1400 550 15 800 1500 550 Mar 1 800 1600 550 15 850 1700 550 Apr 1 900 1800 600 15 950 1900 700 May 1 950 2000 900 15 1000 2000 900 Jun 1 1050 2000 600 15 1050 2000 500 Jul 1 1050 2000 450 15 1050 1750 400 Aug 1 900 1500 350 15 800 1300 350 Sep 1 600 1150 350 15 500 1000 350 Oct 1 500 1000 350 15 500 1000 550 Nov 1 600 1000 550 15 700 1100 600 Dec 1 700 1200 700 15 700 1300 700 (3) Instream flow hydrographs, as represented in the document entitled "Puyallup River basin instream resource protection program," shall be used for definition of instream flows on those days not specifically identified in WAC 173-510-030(2). (4) All consumptive water rights hereafter established shall be expressly, subject to instream flows established in WAC 173-510-030 (1) through (3). (5) At such time as the department of fisheries and/or department of wildlife and the department of ecology shall agree that additional stream management units should be identified other than those specified in WAC 173-510-030(1), the department of ecology shall identify additional control stations and management units on streams and tributaries within the basin and shall further protect instream flows where possible for those stations as provided in chapters 90.22 and 90.54 RCW.
