Dataset of Groundwater and Surface Water Data Collection for the Walla Walla Basin in Washington, 2018-2022

The semi-arid Walla Walla River Basin (WWRB) spans 1,777 square miles in Washington and Oregon and supports a diverse agricultural region as well as cities and rural communities that are partially reliant on groundwater. Historically, surface-water and groundwater data have been collected in the WWRB by federal, state, local, and tribal governments, irrigation districts, universities, and non-profit entities. This data release presents the surface-water and groundwater data collection by the U.S. Geological Survey (USGS) from February 2018 to April 2022. Data were collected and compiled for 237 sites — 191 wells and 46 surface-water discharge sites.
