Source data include daily mean streamflow observations from the National Water Information System (NWIS)
database and daily mean runoff predictions from the National Hydrologic Model Infrastructure application of the
Precipitation-Runoff Modeling System (NHM-PRMS) version 1.0 "byHRU_musk_obs" calibration (Muskingum routing). Daily streamflow errors were calculated by
comparing predicted and observed mean daily flow.
