Each year, the state’s water supply is dependent on rainfall, snowpack, and temperature. Surface and groundwater availability varies by watershed and the sub-basins within those watersheds. Water availability also depends on the water rights held by others in each area.
If you have questions about water availability for a particular property, you’ll want to start by identifying your watershed, also known as a Water Resource Inventory Area or WRIA. You might also want to know some basics about Washington water law so you can better understand how decisions about water use allocations are made.
