Abstract: The Shop Creek retention pond and follow-up wetlands were constructed in 1989, by the City of Aurora, Colorado, and the Cherry Creek Basin Water Quality Authority to enhance urban storm water runoff. Since monitoring began, a total of 107 storm runoff events occurred and water quality data were collected for 36 of these events. The findings of this effort suggests a need for standardized reporting of runoff, watershed, storm separation, and inter-event time parameters along with the performance data for retention ponds and wetlands. In addition, detailed analysis revealed that dry-weather flows can significantly affect seasonal pollutant load removal rates.
