The Hydro Network-Linked Data Index (NLDI) is a system that can index data to NHDPlus V2 catchments and offers a search service to discover indexed information. Data linked to the NLDI includes active NWIS stream gages, water quality portal sites, and outlets of HUC12 watersheds. The NLDI is a core product of the Open Water Data Initiative and is being developed as an open source project..

See implementations of Python APIs with the NLDI: https://github.com/cheginit/pygeohydro

Especially interesting for querying upstream tributaries or downstream diversions from a single USGS station.
