ABSTRACT:
This resource presents data used in the study by van der Heijden et al. (under review, 2025). The data contains monthly mean baseflow indices (BFI) for 1,432 United Stated Geological Survey (USGS) streamflow gages across the Continental United States (CONUS).
The streamflow gages used are those considered of reference-quality by the Geospatial Attributes of Gages for Evaluating Streamflow, version II (GAGES-II) dataset (Falcone, 2011) that contain at least 20 years of continuous daily streamflow measurements.
Baseflow separation was conducted using a single parameter recursive digital low-pass filter based on Lyne and Hollick, (1979) for baseflow separation. The filter, implemented in the R package EcoHydRology (Fuka et al., 2014), was converted to Python (Hamshaw et al., 2020) and as part of this research is now available through the Baseflow Python package developed by Brigham Young University Hydroinformatics group (https://github.com/BYU-Hydroinformatics). The filter parameter was tuned to the long-term flow history of each gage individually using the 10th non-exceedance percentile of streamflow.
