The Walla Walla Basin Watershed Council began its small-order stream and spring monitoring program in 2002 after the agreement to leave base flows in the main stem of the Walla Walla River went into effect. This network's purpose is to provide the community with supplemental water flow data, which can aid the management of the valley's water and support or assuage the fears of the concerned water users.
The Walla Walla Basin Watershed Council currently monitors 24 sites in the Walla Walla Valley, including springs, small-order streams, and irrigation ditch sites. This monitoring network covers an area bounded by Walla Walla, Milton-Freewater, and Touchet. Many of these sites are equipped to provide near real-time data (see links below). Data for our stand-alone monitoring locations is updated on a quarterly basis. Below is a map showing current WWBWC monitoring sites and also sites monitored by the United States Geological Survey (USGS), Oregon Water Resources Department (OWRD), and Washington Department of Ecology (WDOE). To view available data and web links for each site, click on a point. The Google Earth (.kmz) file is also available for download by clicking on the link below. To view historical data, please view our Historical Streamflow Data page. For information regarding how the streamflow data were collected please see the WWBWC's Standard Operating Procedures.
