  • ended Discontinued gauges: 1 gauge has stopped reporting: Black River Near Maverick, Ariz (last 1982). Their segments rest on fewer gauges after those years.

A reading is removed automatically only when it is impossible (for example, a daily mean above the highest flow USGS recorded that water year). Low and zero flows are never removed: rivers here really do dry up.

None.
