| Description | The Total Maximum Daily Load (TMDL) study recommends reducing nutrients, especially nitrogen, in the Walla Walla River and its tributaries so that dissolved oxygen (DO) and pH water quality standards are met. Of 54 sites monitored, 34 did not meet pH criteria and 17 did not meet DO criteria. Near background nutrient levels need to be maintained along watershed streams (a 20 to 99 percent decrease in concentrations). With seasonal (May - October) point source diversion, citizen education, and best management practices, the DO and pH water standards may be met in 10 years from the completion of the Water Quality Implementation Plan. | ||||
