Abstract Long Description

Five swimming areas along the Snoqualmie River were monitored during the summer of 1992 to evaluate bacterial contamination. The results are compared to the state Class A criterion for fecal coliform (FC) and to the federal criteria for enterococci and Escherichia coli (E. coli).

Three swimming areas had bacterial concentrations that exceeded one or both of the criteria. These areas are located at river mile (RM) 9.8 at Duvall, RM 24.9 near Carnation, and RM 39.6 near Fall City. The area at Duvall had significantly higher FC and E. coli concentrations than all other areas except for Carnation.

Further investigation of bacterial sources and implementation of source controls is recommended at these three swimming areas.
