Install
pip install hydrofunctionsAbout hydrofunctions
hydrofunctions keeps the common case simple: request USGS NWIS discharge or stage for one or many gauges, get a pandas DataFrame with sensible column names, cache responses politely, and produce quick hydrographs and flow-duration curves. Its documentation teaches the NWIS service itself as it goes.
For teaching, quick studies and analysts who want data access without adopting a full stack, it remains a tidy, focused tool — with HyRiver the step up when workflows grow spatial.
