Generate a new flood frequency plot for the updated Siletz River data, 1925-2010. That is, generate an updated version of Figure, but only plot the Gamma-3 and LP3 fits. You may omit some data points in the middle of the ordered series to ease crowding. If you are unable to obtain lognormal probability paper, a plot of magnitude vs. log(T) or magnitude vs. log(l-F) can serve as a substitute. That is, plot magnitude on the arithmetic scale vs. T or 1-F on the log scale on semilog paper or in Excel.
