Pump-controlled iron enhanced sand filter basin at the Golden Lake Stormwater Treatment Pond
Golden Lake does not meet state water quality standards due to high phosphorus levels. The proposed iron enhanced sand filter basin was identified in the Golden Lake Subwatershed Stormwater Retrofit Analysis to be one of the most cost effective remaining practices for reducing external phosphorus loads to Golden Lake. This project, paired with two previously installed upstream Best Management Practices, will achieve on average, 84% of the phosphorus reduction goal for the watershed.

40 pounds of phosphorus/year
This project resulted in an estimated annual reduction of 50 lbs of phosphorus.
