Stream discharge is collected on four small watersheds in the Coyote Creek drainage within the South Umpqua Experimental forest in the southwest Oregon Cascades. Stream discharge data was started in October 1963 and discontinued in June 1981 (discontinued April 1985 on Watershed 4). Stream discharge measurement was resumed in December 2000 on all four watersheds. Watersheds 1, 2, and 3 were harvested with differing silvicultural methods in summer 1971, and watershed 4 is the control. High resolution temporal data is provided as well as daily, monthly and annual summary data. Streamflow data by sampling intervals are also provided from 1970 to 1981 when stream water chemistry data were being collected. Annual bedload accumulation totals from each of the four watersheds is also provided beginning 2001.

Examine the effects on streamflow based on differing silvicultural techniques used in the harvesting of three small watersheds in conjunction with a control watershed in the South Umpqua Experimental Forest. Additionally in an effort to relate forest environments to harvesting techniques and subsequent forest regeneration in southwestern Oregon, the U.S. Forest Service monitored and compared these variables on the three adjacent, harvested experimental watersheds.
