Water Resource Permits
Washington State has what appears to be a bountiful water supply. However, because of geographic and seasonal shortages, people cannot always have all the water they feel they need. Also, the total water supply is finite. There will never be more. Washington's population is increasing and along with this growth, there is an associated expanded water demand for all purposes -- domestic, industrial, agricultural, power and recreation. Water is also a critical component of fish habitat. Significant efforts are being undertaken to protect and restore stream flows for fisheries. The permits listed in this section are part of Washington's water resource management strategy, a strategy intended to ensure an adequate and clean supply of water for all purposes.

If the impoundment is to be constructed off- stream and filled from a stream, then a permit for water diversion to fill the impoundment will be required.
