This document contains tables with information for determining values of Yn and σn using the Gumbel Type I method and values of K for the log Pearson Type III distribution method. The log Pearson table lists K factor values for different recurrence intervals in years and skewness coefficients ranging from -3 to -1 and 1 to 3. The table can be used to determine K values based on the weighted skew coefficient and desired exceedance probability or return period.
