New York

StreamStats for New York can be used to estimate instantaneous flood discharges with exceedance probabilities of 0.8, 0.667, 0.5, 0.2, 0.1, 0.04, 0.02, 0.01, 0.005, and 0.002 for ungaged, unregulated, rural streams. These exceedance probabilities correspond to recurrence intervals of 1.25-, 1.5-, 2-, 5-, 10-, 25-, 50-, 100-, and 500-years, respectively. The report below presents the regression equations used to estimate the peak-flow statistics, describes the errors associated with the estimates, and describes the methods used to develop the equations and to measure the basin characteristics used in the equations. Users should familiarize themselves with the report before using StreamStats to obtain estimates of streamflow statistics for ungaged sites.
