Managing our Water

Water Supply

Ecology’s mission is to ensure there is sufficient water to meet the needs of people, agriculture, industry, and fish. The challenge is supplying water for 21st Century needs while operating under 19th Century laws. Through the administration of water rights, the setting of in-stream flows, dam regulations, and water conservation, we are working to protect water supplies for today and for future generations. While protecting and providing an adequate water supply, we also must protect water quality, to ensure safe drinking water and to support wildlife.
