Peak discharges of May 19 and 21, 1966 SUMMARY The storms of May 19 and 21, 1966, produced high rates of runoff on some of the streams in the Jackson area, one exceeding 1,800 cfs per square mile. The peak discharges of these floods are compared with maximum previous peaks in table 1. The peak discharge of Three-Mile Creek was the highest of record. Peak discharges of Town and Lynch Creeks were the highest since the floods of 1953 and 1954. The estimated recurrence interval of these floods is shown in table 1. Isohyetal maps for the storms of May 19 and 21, 1966, are shown on figures 1 and 3, respectively. Comparison of maximum rainfall for selected time intervals with U.S. Weather Bureau frequency curves for the storms of May 19 and 21, 1966, are shown on figures 2 and 4, respectively. The stage and discharge hydrographs for Eubanks Creek at Wood Dale Drive, Town Creek at Gallatin Street, and Lynch Creek at Valley Street for the flood of May 19, 1966, are shown on figures 6,7, and 8, respectively. Flood profiles for the flood of May 19, 1966, along 13 creeks in the Jackson area are presented on figures 9 through 21. The profiles along Purple, Hanging Moss, and Whiteoak Creeks for the flood of May 21, 1966, are presented on figures 22, 23, and 24, respectively. Highwater elevations recovered from previous floods are also shown on these profiles for comparison. A general discussion of each profile is presented in the text.
