Warnings (10)
- warning: copy bias Gila River At Duncan, AZ: The nwps copy runs 36% lower than usgs (median, 54 shared days, Aug 19, 2026 to Nov 1, 2026). The report takes 26 days from nwps where usgs is missing, so the level can shift there.
- warning: gap Gila River At Duncan, AZ: 1 gap of 60+ days inside the record (366 days in all). Longest: Sep 30, 2007 to Sep 29, 2008 (366 days).
- warning: gap Gila River At Head Of Safford Valley, Nr Solomon,: 1 gap of 60+ days inside the record (600 days in all). Longest: Sep 30, 1933 to May 22, 1935 (600 days).
- warning: peak conflict Gila River At Head Of Safford Valley, Nr Solomon,: 3 approved USGS daily values exceed that water year's USGS annual peak, in water years 1942, 1957, 1983 (e.g. 7,530 cfs on Aug 8, 1957 against a peak of 5,980). A day's mean cannot exceed the year's peak, so one of the two USGS records is wrong for those years; the daily values are kept.
- warning: peak conflict Gila River Below Blue Creek, Near Virden, NM: 1 approved USGS daily value exceed that water year's USGS annual peak, in water year 1942 (e.g. 3,370 cfs on Oct 1, 1941 against a peak of 3,140). A day's mean cannot exceed the year's peak, so one of the two USGS records is wrong for those years; the daily values are kept.
- warning: gap Gila River Near Clifton, AZ: 4 gaps of 60+ days inside the record (6,636 days in all). Longest: Jul 1, 1918 to Mar 31, 1928 (3,562 days); Oct 1, 1989 to Sep 30, 1995 (2,191 days); Sep 30, 1933 to Apr 30, 1935 (578 days).
- warning: peak conflict Gila River Near Clifton, AZ: 1 approved USGS daily value exceed that water year's USGS annual peak, in water year 1942 (e.g. 6,130 cfs on Oct 1, 1941 against a peak of 3,280). A day's mean cannot exceed the year's peak, so one of the two USGS records is wrong for those years; the daily values are kept.

A day's mean cannot exceed the year's peak, so one of the two USGS records is wrong for those years; the daily values are kept.

Context (8)
Show 8 notes
- ended Discontinued gauges: 2 gauges have stopped reporting: Gila R Nr Silver City, NM (last 1919); Gila River Near Cliff, NM (last 1951). Their segments rest on fewer gauges after those years.
- zero run Gila River At Duncan, AZ: 2 runs of 60+ days at zero flow; longest 117 days from Aug 16, 2023; 80 days from Sep 17, 2020. Usually real (a dry channel or no release), not missing data.
- copy disagree Gila River Below Blue Creek, Near Virden, NM: The usace_cwms copy agrees on the median but differs by more than 10% on 57% of 5,058 shared days (often provisional vs approved data, or a different daily averaging window). The report takes 1 days from usace_cwms where usgs is missing, so the level can shift there.
- gap Gila River Below Blue Creek, Near Virden, NM: 1 gap of 60+ days inside the record (122 days in all). Longest: Mar 1, 1979 to Jun 30, 1979 (122 days).
- flatline Gila River Near Clifton, AZ: 1 run of 30+ days at exactly the same flow: 14.0 cfs for 31 days from Nov 9, 1953. Usually an estimated period (ice, a broken gauge) rather than measured daily flow.
- copy disagree Gila River Near Gila, NM: The usace_cwms copy agrees on the median but differs by more than 10% on 33% of 6,114 shared days (often provisional vs approved data, or a different daily averaging window). The report takes 363 days from usace_cwms where usgs is missing, so the level can shift there.
- copy disagree Gila River Near Redrock, NM: The usace_cwms copy agrees on the median but differs by more than 10% on 50% of 5,575 shared days (often provisional vs approved data, or a different daily averaging window). The report takes 755 days from usace_cwms where usgs is missing, so the level can shift there.
- single gauge Upper Gila: 93% 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.
Values removed (6)
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.
