    Abstract - Using a low flow season defined as a function of antecedent precipitation, streamflow data for a 21 year period was analyzed to determine the effects of selective tractor harvesting of second-growth Douglas-fir and redwood forest on the volume, timing, and duration of low flows and annual water yield. Significant increases in streamflow were detected for both the annual period and the low flow season. Maximum increases were realized the year following the completion. of logging. Greater relative increases were witnessed for the summer low flow period, however these increases were short-lived in comparison to the overall increase in annual water yield.
