- ended Discontinued gauges: 1 gauge has stopped reporting: Rito Blanco Near Pagosa Springs, CO (last 1952). Their segments rest on fewer gauges after those years.
- flatline Rito Blanco Near Pagosa Springs, CO: 6 runs of 30+ days at exactly the same flow: 1.0 cfs for 31 days from Dec 1, 1942; 1.6 cfs for 31 days from Dec 1, 1944; 1.7 cfs for 31 days from Jan 1, 1945. Usually an estimated period (ice, a broken gauge) rather than measured daily flow.
Values removed (0)
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.
