Washington Revised Code Title 90. Water Rights--Environment § 90.22.040. Stockwatering requirements

It shall be the policy of the state, and the department of ecology shall be so guided in the implementation of RCW 90.22.010 and 90.22.020, to retain sufficient minimum flows or levels in streams, lakes or other public waters to provide adequate waters in such water sources to satisfy stockwatering requirements for stock on riparian grazing lands which drink directly therefrom where such retention shall not result in an unconscionable waste of public waters. The policy hereof shall not apply to stockwatering relating to feed lots and other activities which are not related to normal stockgrazing land uses.
