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

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 (2)
- warning: seasonal Vermejo River At Vermejo Park, NM: No record in Nov–Mar most years: the gauge reports seasonally, so yearly and some monthly means are missing or cover only part of the year.
- warning: gap Vermejo River Near Dawson, NM: 2 gaps of 60+ days inside the record (2,554 days in all). Longest: Jun 1, 1921 to Feb 28, 1927 (2,099 days); Jan 1, 1918 to Mar 31, 1919 (455 days).
Context (5)
Show 5 notes
- single gauge Canadian Headwaters: 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.
- ended Discontinued gauges: 2 gauges have stopped reporting: Vermejo River At Vermejo Park, NM (last 1993); Vermejo River Near Maxwell, NM (last 1994). Their segments rest on fewer gauges after those years.
- gap Vermejo River At Vermejo Park, NM: 1 gap of 60+ days inside the record (224 days in all). Longest: Oct 19, 1990 to May 30, 1991 (224 days).
- flatline Vermejo River Near Dawson, NM: 3 runs of 30+ days at exactly the same flow: 4.3 cfs for 86 days from Nov 11, 2018; 6.0 cfs for 48 days from Dec 15, 1943; 2.5 cfs for 35 days from Nov 27, 1937. Usually an estimated period (ice, a broken gauge) rather than measured daily flow.
- spike Vermejo River Near Dawson, NM: 2 single-day flows far above the gauge's usual range (99th percentile 172 cfs) with no annual peak on record to confirm them: 2,300 cfs on Sep 1, 2002; 900 cfs on Aug 24, 1927. Flash floods are common here, but these are unverified.
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.
