Description The Black Diamond Wastewater Treatment Facility (WWTF) discharges treated sewage to a wetland, which drains to Rock Creek and then Lake Sawyer. Total phosphorus concentrations in Lake Sawyer increased following start-up of the WWTF. The observed increase in whole-lake total P content corresponds closely to the estimated loading currently discharged from the WWTF. The condition of Lake Sawyer is predicted to reach a eutrophic state in the future (2010) if discharges from the Black Diamond WWTF continue at existing or currently permitted levels of treatment.
