| Short Description |
A water quality screening of the Chehalis River basin was performed during January and March 1991. The objective of the study was to identify problem areas associated with runoff conditions, particularly those areas with elevated fecal coliform bacteria concentrations. Water quality data collected basin-wide were evaluated, and water quality problems were documented for low dissolved oxygen and elevated fecal coliform, nitrate, conductivity, and pH. Data collected during this project resulted in the initiation of a total maximum daily load (TMDL) study for fecal coliform bacteria in the Black River drainage. (Also see abstract below) | |||

| Abstract | Long Description |
A water quality screening of the Chehalis River basin was performed during January and March 1991. The objective of the study was to identify problem areas associated with runoff conditions, particularly those areas with elevated fecal coliform bacteria concentrations. Water quality data collected basin-wide were evaluated, and water quality problems were documented for low dissolved oxygen and elevated fecal coliform, nitrate, conductivity, and pH. Data collected during this project resulted in the initiation of a total maximum daily load (TMDL) study for fecal coliform bacteria in the Black River drainage. Low moisture conditions predominated in the basin during the study period; therefore, additional monitoring would be needed to accurately characterize runoff conditions. |
