Low-flow and flow-duration characteristics of Alabama streams

Estimates of minimum 7-day average discharges with recurrence intervals of 2 and 10 years for 228 continuous-record gaging stations are presented in this report. Low-flow frequency discharge estimates for 447 partial-record stations are also presented. These discharge estimates were computed by relating base-flow discharge measurements at the partial- record stations to daily-mean discharge values at selected continuous-record gaging stations. Flow- duration characteristics for 207 continuous-record gaging stations are also provided.
