Context (6)
Show 6 notes
- single gauge Alamosa-Trinchera: 77% of this segment's weeks rest on a single gauge; the segment value is that gauge in those weeks, and jumps when other gauges join or drop out.
- fallback Culebra Creek At San Luis, CO: 65% of days come from usgs; codwr 35% fill days usgs does not cover, so the source changes within the record.
- flatline Culebra Creek At San Luis, CO: 15 runs of 30+ days at exactly the same flow: 23.0 cfs for 145 days from Nov 1, 1927; 25.0 cfs for 90 days from Dec 1, 1930; 25.0 cfs for 71 days from Nov 22, 1931. Usually an estimated period (ice, a broken gauge) rather than measured daily flow.
- flatline Culebra Creek Below San Luis, CO: 8 runs of 30+ days at exactly the same flow: 43.0 cfs for 59 days from Jan 1, 1939; 35.0 cfs for 52 days from Dec 11, 1939; 42.0 cfs for 31 days from Dec 1, 1938. Usually an estimated period (ice, a broken gauge) rather than measured daily flow.
- fallback Culebra Creek Near Chama, CO: 64% of days come from usgs; codwr 36% fill days usgs does not cover, so the source changes within the record.
- ended Discontinued gauges: 1 gauge has stopped reporting: Culebra Creek Below San Luis, CO (last 1955). Their segments rest on fewer gauges after those years.
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.
