Streamgage
A streamgage is a USGS (or partner) site measuring stage and often discharge on a river or stream. Streamgages on inflows or tailwaters help explain reservoir behavior but are not always at the main pool gage.
Why it matters
A rising pool gage plus a falling upstream streamgage tells a different story than both rising together. Anglers tracking creek arms and tournament directors watching river flow both lean on USGS networks where they exist.
