Stream discharge is collected on three small watersheds in the headwaters of Drift Creek, a tributary of the Alsea River in the northern Oregon Coast Range. Stream discharge data collection was started in October 1959 and discontinued after September 1973. One watershed was clearcut (Needle Branch) in 1966, the second (Deer Creek) was clearcut in patches with buffer strips covering 25 percent of the area in 1966, and the third (Flynn Creek) was unlogged and served as a control. The daily mean flow data were originally published by the USGS. In 2000, the original streamflow charts were digitized to produce a high temporal resolution record and these data are provided here. The daily, monthly and annual summaries were reproduced from these re-digitized data. For comparison purposes, the original USGS daily data and associated monthly and annual summary data are also provided.

Three small headwater streams were monitored during a 15 year study to look at the influences of patch and complete clearcut logging on water yield, water temperature and water quality. The overall purpose was to consider direct and indirect effects of logging on fish populations and effects on environmental and physical properties of streams. This data set primarily addresses changes in water yield based on pre- and post-harvest measurements of stream discharge on two watersheds in conjunction with a control watershed.
