Equations for estimating the magnitude and frequency of floods for small rural streams in Alabama are presented for recurrence intervals ranging from 2 to 500 years. Floodfrequency characteristics are documented for 43 streamflow gaging stations included in the analysis. Each station used has a drainage area less than 15 square miles and at least 10 years of record prior to 2003. None of these stations were affected by regulation or urbanization. Regression relations were developed using generalized least-square techniques to estimate flood magnitude and frequency on ungaged streams as a function of the drainage area of a
