**Please note, the water quality summaries now reflect an update to Washington State water quality standards for fecal bacteria in the Birch Bay watershed. The current benchmarks used for fecal coliform are consistent with the benchmarks used for other watersheds evaluated by the PIC Program. Meeting these fecal coliform benchmarks in freshwater systems leads to satisfying the Washington State marine water standards to protect public health.
