Description:

Accumulated water quality monitoring data indicates that Palouse River mainstem and south fork waters (17060108) suffer severe pollution problems throughout the year. South fork stations were more seriously affected. Coliform levels were generally far in excess of water quality standards at all stations, with south fork counts being substantially higher than those of the mainstem. The Pullman STP does not appear to be a major contributor of coliform organisms to the south fork. Bacterial population density increased from winter through summer quarters. Nitrate and orthophosphate concentrations were sufficient for algae bloom potential at nearly all stations throughout the year. Nitrite and ammonia concentrations were high enough to indicate organic pollution, though mainstem levels were for the most part acceptable. Temperature and pH violations were noted for both south fork and mainstem stations during the summer months. It is felt that organic pollution in conjunction with increased temperatures were the major causes of dissolved oxygen violations. Stanley, R.F. 1973.
