The original, published streamflow data from the Wagon Wheel Gap watershed deforestation study were analyzed using modem computational and statistical methods. Annual hydrograph parameters were generated for the two paired watersheds for the pre- and postreatment periods and tested using regression and covariance analyses. Average annual water yield, maximum daily discharge, high-flow volumes, recession flows, and baseflow were all increased significantly following complete deforestation of one watershed. With the exception of the first full year after treatment, deforestation had little effect on hydrograph timing. Deforestation increased both the slope and intercept of a linear equation describing the flow duration curve of Watershed B. The results for these major hydrograph parameters agree with the results reported from the original study, conducted between 1910 and 1926 at Wagon Wheel Gap, Colorado. However, some of the original study results for other hydrograph parameters could not be statistically supported. For. Sci. 34(1):208-214.
