Description The 303(d) fecal coliform bacteria, dissolved oxygen, pH, and arsenic listings in the Stillaguamish River watershed and Port Susan were assessed. Fecal coliform load reductions are recommended for freshwater reaches and Port Susan. Stormwater wasteload allocations for fecal coliform and BOD were developed for three jurisdictions, and wasteload allocations for fecal coliform were developed for three municipal wastewater treatment plants. Seasonal dissolved oxygen targets, some below the Class A criterion of 8 mg/L, are proposed as minimum potential concentrations after pollutants sources are removed. Data suggest that both arsenic and mercury are from natural sources in the basin.
