Santa Cruz 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.
Warnings (1)
- warning: peak conflict Santa Cruz River Near Cundiyo, NM: 1 approved USGS daily value exceed that water year's USGS annual peak, in water year 1991 (e.g. 606 cfs on May 22, 1991 against a peak of 416). 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 (4)
Show 4 notes
- ended Discontinued gauges: 1 gauge has stopped reporting: Santa Cruz R A Riverside, NM (last 1951). Their segments rest on fewer gauges after those years.
- zero run Santa Cruz R A Riverside, NM: 2 runs of 60+ days at zero flow; longest 160 days from Jul 11, 1950; 65 days from Feb 13, 1951. Usually real (a dry channel or no release), not missing data.
- flatline Santa Cruz River Near Cundiyo, NM: 2 runs of 30+ days at exactly the same flow: 10.0 cfs for 54 days from Jan 1, 1936; 7.5 cfs for 31 days from Dec 1, 1953. Usually an estimated period (ice, a broken gauge) rather than measured daily flow.
- single gauge Upper Rio Grande: 90% 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 (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.
