Context (4)
Show 4 notes
- single gauge Alamosa-Trinchera: 97% 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 La Jara Creek At Gallegos Ranch, Nr Capulin, CO: 44% of days come from usgs; codwr 56% fill days usgs does not cover, so the source changes within the record.
- flatline La Jara Creek At Gallegos Ranch, Nr Capulin, CO: 41 runs of 30+ days at exactly the same flow: 6.0 cfs for 60 days from Jan 1, 1952; 7.0 cfs for 59 days from Feb 1, 1958; 6.0 cfs for 44 days from Nov 18, 1957. Usually an estimated period (ice, a broken gauge) rather than measured daily flow.
- gap La Jara Reservoir Outlet: 1 gap of 60+ days inside the record (80 days in all). Longest: Jan 10, 2024 to Mar 29, 2024 (80 days).
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.
