| Description | This Walla Walla River Basin Effectiveness Monitoring (EM) study compared 2014-2015 instream water quality data to the 2002-2003 Total Maximum Daily Load (TMDL) study data. The TMDL set interim fecal coliform bacteria (FC) and nutrient reduction targets for 2014 to improve the basin’s water quality. From July 2014 through June 2015, lower basin sites and sites in and below cities and towns, continued to have high FC counts, low daily minimum dissolved oxygen (DO), and high daily maximum pH. Trend tests showed declining lower-basin FC and nutrient loads since the TMDL. Meeting water quality standards will require further identification and correction of point and nonpoint sources throughout the Walla Walla River Basin. We recommend the Department of Ecology and Walla Walla Basin stakeholders gather best management practice (BMP) data to (1) assess implementation progress and (2) conduct source tracking for specific locations with high FC and nutrient concentrations. The Appendices file is available under View Now above. |
