Six methods were used to estimate the magnitude and frequency of floods at Pochack Creek at the down- stream end of the culvert on United States Route 130 and at a second site about 1,600 feet upstream at Pennsauken Township, New Jersey. Flood magnitude and frequency calculated by the six methods, as well as drainage-basin characteristics, are included in this report. The 100-year-flood estimates for the culvert site range from 280 cubic feet per second to 2,600 cubic feet per second. The 100-year-flood estimates for the upstream site range from 216 cubic feet per second to 1,800 cubic feet per second. Flood magni- tude and frequency estimates obtained by using the New Jersey Department of Environmental Protection Special Report 38 method fall within the range of values estimated by using the U.S. Geological Survey transfer method with data collected from three nearby crest-stage gages.
