Canadian River
Streamflow, conditions and background by watershed segment. Data through November 1, 2026.
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.

Show 16 notes
- flatline Canadian River At Logan, NM: 7 runs of 30+ days at exactly the same flow: 10.0 cfs for 61 days from May 1, 1934; 120.0 cfs for 31 days from Oct 1, 1911; 35.0 cfs for 31 days from Dec 1, 1911. Usually an estimated period (ice, a broken gauge) rather than measured daily flow.
- zero run Canadian River At Logan, NM: 7 runs of 60+ days at zero flow; longest 122 days from Sep 1, 1956; 110 days from Jan 13, 1935. Usually real (a dry channel or no release), not missing data.
- flatline Canadian River Below Conchas Dam, NM: 14 runs of 30+ days at exactly the same flow: 3.0 cfs for 94 days from Dec 21, 1962; 1.0 cfs for 49 days from Dec 13, 1957; 1.0 cfs for 46 days from Oct 8, 1954. Below a dam this is usually a steady set release, which is real flow.
- spike Canadian River Below Conchas Dam, NM: 7 single-day flows far above the gauge's usual range (99th percentile 1,358 cfs) with no annual peak on record to confirm them: 13,100 cfs on May 8, 1942; 9,800 cfs on Sep 17, 1942; 7,920 cfs on May 15, 1942. Flash floods are common here, but these are unverified.
- zero run Canadian River Below Conchas Dam, NM: 1 run of 60+ days at zero flow; longest 116 days from Jan 28, 1955. Usually real (a dry channel or no release), not missing data.
- spike Canadian River Near Hebron, NM: 1 single-day flow far above the gauge's usual range (99th percentile 148 cfs) with no annual peak on record to confirm them: 7,800 cfs on Jun 17, 1965. Flash floods are common here, but these are unverified.
- zero run Canadian River Near Hebron, NM: 2 runs of 60+ days at zero flow; longest 69 days from Sep 23, 1964; 61 days from Nov 26, 1953. Usually real (a dry channel or no release), not missing data.
- zero run Canadian River Near Roy, NM: 1 run of 60+ days at zero flow; longest 186 days from Sep 5, 1956. Usually real (a dry channel or no release), not missing data.
- zero run Canadian River Near Sanchez, NM: 2 runs of 60+ days at zero flow; longest 117 days from Jul 16, 2003; 68 days from May 22, 1974. Usually real (a dry channel or no release), not missing data.
- copy disagree Canadian River Near Taylor Springs, NM: The usace_cwms copy agrees on the median but differs by more than 10% on 28% of 1,792 shared days (often provisional vs approved data, or a different daily averaging window). The report does not use usace_cwms for this gauge.
- flatline Canadian River Near Taylor Springs, NM: 6 runs of 30+ days at exactly the same flow: 6.0 cfs for 61 days from Oct 1, 1939; 6.0 cfs for 54 days from Nov 8, 1952; 1.0 cfs for 40 days from Jan 19, 1957. Usually an estimated period (ice, a broken gauge) rather than measured daily flow.
- spike Canadian River Near Taylor Springs, NM: 1 single-day flow far above the gauge's usual range (99th percentile 951 cfs) with no annual peak on record to confirm them: 4,850 cfs on Jul 7, 1947. Flash floods are common here, but these are unverified.
- zero run Canadian River Near Taylor Springs, NM: 4 runs of 60+ days at zero flow; longest 191 days from Sep 19, 2021; 85 days from Sep 11, 2020. Usually real (a dry channel or no release), not missing data.
- zero run Canadian Rv Nr Amarillo, TX: 1 run of 60+ days at zero flow; longest 65 days from Aug 18, 2000. Usually real (a dry channel or no release), not missing data.
- ended Discontinued gauges: 3 gauges have stopped reporting: Canadian River Near Roy, NM (last 1965); Canadian River Below Conchas Dam, NM (last 1972); Canadian River Near Hebron, NM (last 1986). Their segments rest on fewer gauges after those years.
- single gauge Upper Canadian-Ute Reservoir: 68% 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 (2)
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.
