Groundwater Monitoring

The primary objective of WWBWC’s Alluvial Aquifer Monitoring Project is to collect groundwater level data from the Oregon portion of the basin, identify long-term aquifer trends, and use that information to support collaborative water management solutions in the bi-state basin. The monitoring network also tracks the effectiveness of artificial recharge (AR) testing. 

The Walla Walla Valley River Basin is approximately 1,760 square miles, with an underlying shallow alluvial aquifer of 200 square miles.  Many farmers, businesses, and residents use water from the shallow aquifer, making it a highly important source of water for the Walla Walla Valley. In addition to supplying wells with groundwater, the shallow aquifer also provides cold, clean water to dozens of springs and streams of the Walla Walla Basin.

 

WWBWC currently monitors 63 wells in the Walla Walla Valley.  Data are updated online on a quarterly basis.  Below is a map showing the location of each well.  To view and download available data, click on a colored pin.  Please download the Metadata file for information about data quality and data table information.  The Google Earth (.kmz) file is also available for download by clicking on the link below the map.  For information regarding how the groundwater data were collected, please see WWBWC's approved Oregon Department of Environmental Quality (DEQ) Sampling and Analysis Plan.  For more information, please see the WWBWC's Standard Operating Procedures.
