ABSTRACT A cooperative program of the U.S. Geological Survey and the City of Jackson has provided for the collection of flood records from Jackson streams since 1953. This report con- sists of a preliminary analysis of the flood data that have been collected under this program. The analysis is limited to a study of the peak discharges. The report "Floods in Mississippi, Magnitude and Frequency" was published by the Mississippi State Highway Department in 1961. It presented curves from which the magnitude and frequency of floods from most rural drainage areas can be estimated by using independent variables of size, shape, and location of basin. The urgent need for flood-frequency data on small urbanized areas necessitated this report on Jackson's streams. The streams analyzed are Eubanks, Town, Lynch, and Three-Mile Creeks. Their drainage basins above the gaged points are outlined on figure 1, a topographic map of Jackson. LizardTech's Djvu plug-in is needed to view these reports.
