Washington Revised Code Title 70A. Environmental Health and Safety § 70A.10.190. Legislative declaration

The legislature finds and declares that when prolonged lack of precipitation or shortages of water supply in the state cause severe hardships affecting the health, safety, and welfare of the people of the state, a program to increase precipitation is occasionally needed for the generation of hydroelectric power, for domestic purposes, and to alleviate hardships created by the threat of forest fires and shortages of water for agriculture. Cloud seeding has been demonstrated to be such a program of weather modification with increasing scientific certainty.
