Willow Creek (Rio Grande-Elephant Butte)
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 Willow C Ab Heron Re Nr Los Ojos, NM: 1 approved USGS daily value exceed that water year's USGS annual peak, in water year 1980 (e.g. 1,220 cfs on Apr 22, 1980 against a peak of 1,100). 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 (5)
Show 5 notes
- ended Discontinued gauges: 2 gauges have stopped reporting: Willow Cr Abv Azotea Cr Nr Park View, NM (last 1973); Willow C Ab Heron Re Nr Los Ojos, NM (last 2008). Their segments rest on fewer gauges after those years.
- single gauge Rio Chama: 94% 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.
- flatline Willow C Ab Heron Re Nr Los Ojos, NM: 1 run of 30+ days at exactly the same flow: 1.1 cfs for 42 days from Feb 1, 1977. Usually an estimated period (ice, a broken gauge) rather than measured daily flow.
- zero run Willow C Ab Heron Re Nr Los Ojos, NM: 13 runs of 60+ days at zero flow; longest 273 days from Jun 14, 2002; 174 days from Sep 22, 2001. Usually real (a dry channel or no release), not missing data.
- zero run Willow Cr Abv Azotea Cr Nr Park View, NM: 2 runs of 60+ days at zero flow; longest 90 days from Dec 1, 1972; 76 days from Oct 17, 1973. 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.
