Washington is divided into 62 Water Resource Inventory Areas (WRIAs) based on natural watersheds. Due to Washington’s varied land uses, hydrology, and precipitation levels, the amount of water available for new water right permits varies dramatically across the state.
What is a WRIA?
WRIAs are areas defined by higher elevation that capture precipitation and funnel rain and snowmelt through smaller subbasins into streams, tributaries, and rivers. Due to Washington’s varied terrain and precipitation levels, water availability is different in each location.
Water availability in your WRIA
We are posting water availability focus sheets for each WRIA in the state. You can learn more about the key factors affecting water availability in your WRIA using the links in the table below. Note: Some of these pages are still being developed. If you don’t see a link to information for the WRIA you’re looking for, check back soon.
