ABSTRACT

Knowing the magnitude and frequency of floods on a regional basis does not always meet all the needs for flood information. It is often helpful to know at-site peak stages and discharges; such information can provide a better understanding of the hydraulic and hydrologic characteristics of flooding at a particular stream site. Annual peak stages and discharges are presented in this report for 341 streamflow-gaging stations in Missis- sippi. Gage location, type of gage, gage datum, basin characteristics (drainage area, slope, and length), statistics of logarithms of annual peak discharge (mean, standard deviation, and skew), and selected flood- frequency discharges with recurrence intervals from 2 to 500 years are also presented, if available.
