Water Temperature Monitoring

The WWBWC collects water temperature data on the Walla Walla River at over 25 sites from the Oregon/Washington border up to the BLM Deduct Spring on the South Fork Walla Walla River.  Temperature data loggers are deployed in the river in the late spring/early summer after water levels dropped to safe levels. Sites cover the majority of the South Fork and Mainstem Walla Walla Rivers and capture inputs from the North Fork Walla Walla River. Sites start in the upper basin, near the BLM boundary, and extended downstream capturing temperature changes in the river as it travels down the canyon, approaches the city of Milton-Freewater and then enters the municipal levee with reduced vegetation.  Monitoring continues through the levee and below to the stateline to capture high water temperature values and cooling effects of groundwater returns below the levee system.  Below is a map showing current WWBWC monitoring sites.  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.  For information regarding how the water temperature data were collected please see the WWBWC's Standard Operating Procedures.
