Flood Magnitude and Frequency of Little Mantua Creek at the Culvert at Milepost 7.8 on New Jersey Route 44, and at the Conrail Culvert 0.20 Miles Downstream, West Deptford Township, Gloucester County, New Jersey

By Thomas Barringer

Abstract The magnitude and frequency of floods at Little Mantua Creek at the culvert on New Jersey Route 44 at milepost 7.8 and at the Conrail culvert 0.20 miles downstream, in West Deptford Township, New Jersey, were determined by using the New Jersey Department of Environmental Protection Special Report 38 method. Flood-magnitude and -frequency estimates, as well as drainage-basin characteristics, are included in this report. The 100-year-flood estimates are 249 cubic feet per second at the culvert on New Jersey Route 44, and 243 cubic feet per second at the Conrail culvert.
