Abstract
  • We examined long-term changes in daily streamflow associated with forestry practices with two datasets (this one and the original Alsea Streamflow dataset (1972) over a 60-year period (1959–2017) in the Alsea Watershed Study, Oregon Coast Range, Pacific Northwest, USA. In this contemporary period, 2006 to 2017 (12 water years), data were collected at 10-minute intervals, including three to eight years of pre-harvest data rating curves were developed. Based 40 to 55 stage-discharge data points collected for each watershed. Each watershed has datasets describing the paired stage heights at both pre and post-harvest periods, the corrected stages based on reference and electronic readings, and flows calculated based upon the rating curve and stage heights. All measurements are in feet (ft), meters (m), cubic feet per second (cfs), or cubic meters per second (cms).
