Here is the opinion in Swinomish Indian Tribal Community v. Washington Dept. of Ecology (PDF).
An excerpt:
This case involves the validity of an amended rule from the Department of Ecology (Ecology) that reserves water from the Skagit River system for future year-round out-of-stream uses, despite the fact that in times of low stream flows these uses will impair established minimum instream flows necessary for fish, wildlife, recreation, navigation, scenic and aesthetic values. Ecology relies on RCW 90.54.020(3)(a) for authority to make the reservations of water despite the existing minimum flows. This statutory provision allows impairment of stream base flows when overriding considerations of public interest are served. The Swinomish Indian Tribal Community (Tribe) petitioned for review in superior court, challenging the validity of Ecology’s amended rule reserving the water.
