A basic problem in hydrology is the computation of confidence levels for the value of the T ‐year flood when it is obtained from a log Pearson III distribution using the estimated mean, estimated standard deviation, and estimated skew. Here we give a practical method for finding approximate one‐sided or two‐sided confidence intervals for the 100‐year flood based on data from a single site. These confidence intervals are generally accurate to within a percent or two, as tested by simulations, and are obtained by use of a neural network.
