Data gaps and disparities
Found automatically in the gauge records behind this river, and notes from a reviewer who checked them against other sources. Gauges need at least 26 weeks of daily data to appear on the Flow tab.
Warnings (4)
- warning: gap Jemez R Bl East Fork Nr Jemez Springs, NM: 8 gaps of 60+ days inside the record (3,264 days in all). Longest: Sep 30, 1976 to Jul 14, 1981 (1,749 days); Oct 1, 1956 to May 24, 1957 (236 days); Oct 1, 1953 to May 21, 1954 (233 days).
- warning: gap Jemez River Below Jemez Canyon Dam, NM: 1 gap of 60+ days inside the record (2,009 days in all). Longest: Sep 30, 1937 to Mar 31, 1943 (2,009 days).
- warning: gap Jemez River Near Jemez, NM: 2 gaps of 60+ days inside the record (3,958 days in all). Longest: May 1, 1941 to Sep 30, 1949 (3,075 days); Sep 30, 1950 to Feb 28, 1953 (883 days).
- warning: peak conflict Jemez River Near Jemez, NM: 22 approved USGS daily values exceed that water year's USGS annual peak, in water year 1958 (e.g. 3,160 cfs on Apr 21, 1958 against a peak of 919). 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 (6)
Show 6 notes
- ended Discontinued gauges: 1 gauge has stopped reporting: Jemez R Bl East Fork Nr Jemez Springs, NM (last 1990). Their segments rest on fewer gauges after those years.
- flatline Jemez R Bl East Fork Nr Jemez Springs, NM: 1 run of 30+ days at exactly the same flow: 12.0 cfs for 31 days from Jan 1, 1961. Usually an estimated period (ice, a broken gauge) rather than measured daily flow.
- fallback Jemez River Below Jemez Canyon Dam, NM: 80% of days come from usgs; usbr_hydrodata 20% fill days usgs does not cover, so the source changes within the record.
- flatline Jemez River Below Jemez Canyon Dam, NM: 2 runs of 30+ days at exactly the same flow: 40.0 cfs for 31 days from Jan 1, 1944; 20.0 cfs for 30 days from Oct 13, 1983. Below a dam this is usually a steady set release, which is real flow.
- zero run Jemez River Below Jemez Canyon Dam, NM: 12 runs of 60+ days at zero flow; longest 102 days from Aug 10, 2020; 98 days from May 16, 1963. Usually real (a dry channel or no release), not missing data.
- zero run Jemez River Outlet Below Jemez Canyon Dam, NM: 3 runs of 60+ days at zero flow; longest 102 days from Aug 10, 2020; 84 days from Aug 30, 2023. Usually real (a dry channel or no release), not missing data.
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.
