Requires the department of ecology to amend chapter 173-503 WAC (instream resources protection program--lower and upper Skagit water resources inventory area--WRIA 3 and 4) to be consistent with the 1996 memorandum of agreement regarding the use of Skagit basin water resources for instream and out-of-stream purposes. The amendment resolves the shortage of water available for development in WRIA 3 and 4 by providing increased access to potable water.
