We manage the state's water supply to meet the needs of people and the natural environment, in partnership with Washington communities. Water availability is increasingly limited in Washington due to the pressures of warming temperatures on snowpack and declining aquifers. We are committed to meeting current and future water needs to secure a healthy environment for generations to come.
We study and regulate water resources by watershed. Find yours and see water availability.
We help protect rivers and streams while providing water for rural areas.
A water right is the legal authorization to use a quantity of water for beneficial uses.
We provide well information and regulatory guidance for property owners and well drillers.
Our water supply and enhancement projects are providing water security in Eastern Washington.
We regulate more than 1,100 dams in Washington.
An instream flow is a water right for the stream and the resources that depend on it.
As water for new uses becomes harder to find, we look for innovative solutions to meet future needs.
