Synopsis Erosion and Sedimentation Following Road Construction and Timber Harvest on Unstable Soils in Three Small Western Oregon Watersheds (Classic Reprint) by : R. L. Fredriksen
Excerpt from Erosion and Sedimentation Following Road Construction and Timber Harvest on Unstable Soils in Three Small Western Oregon Watersheds Logging of old growth Douglas - fir timber by high-lead cable methods was completed during the Winter of 1962-63 on three clearcuts of 13, 20, and 28 acres. The logging removed timber from 25 percent of the watershed (fig. Logging debris was burned in September 1963.

Synopsis Oregon Watersheds by : Barry T. Hill
Describes: (1) the human activities that may have contributed to the high turbidity levels in western Oregon's municipal watersheds in Feb. 1996, & (2) the efforts under way by federal, state, local, & private land managers & owners, as well as the affected cities, to ensure safe drinking water during future storms. The review is limited to five municipal watersheds -- those serving the cities of Cottage Grove, Eugene, Portland, Salem, & Sandy. Contains recommendations to the Secretary of Agriculture & of the Interior designed to increase the efficiency & effectiveness of efforts to improve water quality & ensure safe drinking water for cities in western Oregon.

Synopsis Studies on Effects of Watershed Practices on Streams by : James T. Krygier
A number of studies were undertaken related to effects of clearcut logging on water quality and the process affected in small streams. Water temperature studied before and after logging was increased significantly where stream cover was removed. Energy balances of small streams were measured and predictive models were developed. Road building significantly increased sediment yield in clearcut and patch cut watersheds. Logging itself was not an important sediment contributor. Methods for sampling bed load and suspended sediment were developed. Bed load constituted 70 percent of suspended load during peak discharges.
