| Notes | “The combined results seem to show that more surface water is leaving the watersheds for a given amount of precipitation after logging than before. Total runoff, peak flows, and high-flow volumes have increased. The number of low-flow days has decreased; conversely, the number of high-flow days has increased. Extreme low flows have stayed the same or decreased slightly. Sediment concentrations, sediment yields, and water temperatures increased greatly after clearcut logging and slightly after patch-cut logging. Six years after clearcut logging, sediment yields almost returned to prelogging conditions. Seven years after clearcutting (1973), water temperatures are approaching prelogging conditions.” (p.28, 30) |
