Integrated streamflow, water presence, and meteorological drivers for stream network modeling in the HJ Andrews Experimental Forest

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 08:30 PM | Dataset Last Updated: April 27, 2026 at 12:00 AM
This data release provides integrated datasets for modeling streamflow and water presence across the HJ Andrews Experimental Forest stream network in western Oregon. The data include daily meteorological drivers from GRIDMET (precipitation, temperature, humidity, radiation, wind speed, evapotranspiration, vapor pressure deficit), observations of stream discharge and wet/dry status from gaging stations, sensors, and manual observations, static catchment characteristics (elevation, slope, aspect, curvature, drainage area), and National Hydrography Dataset High Resolution stream network topology. These datasets support development of machine learning models that integrate categorical water presence observations with continuous streamflow measurements to improve hydrologic predictions in headwater streams, where traditional streamflow gaging is sparse.
