The Springfield Pond was constructed in 2009 and is located within the west central portion of the Garners Creek Watershed. Specifically, the Springfield Pond is located east of Stoney Brook Road, south of Creekview Lane, west of Eisenhower Drive and north of Springfield Drive within the Town of Buchanan. Approximately 674 acres drain into the Springfield Pond, including areas from the City of Appleton and Town of Buchanan. Stormwater runoff is carried to the pond by road ditches, storm sewers, culverts and Garners Creek.
The purpose of the Springfield Pond is to reduce peak flow rates, improve water quality and provide flood control. Stormwater runoff is temporarily stored within the pond and slowly released through an outlet structure that drains into Garners Creek on the north side of Creekview Lane. Stormwater pollutants are removed as runoff flows through the wet pond. Pollutants slowly settle out and become trapped in the pondís permanent pool of water. Additional pollutant removal is provided by the pondís wetland plantings. The pond reduces the amount of total suspended solids (TSS) and total phosphorus (TP) discharged to Garners Creek by approximately 65% and 50%, respectively. During dry weather, the permanent pool of water has a surface area of 2.9 acres and a maximum depth of 8 feet. During a 100-year rainfall event, the Springfield Pond provides 14.9 million gallons of storage volume and reduces peak flow rates by 61%.
