Reviewed
- Pecos River At Pierce Canyon Crossing, NM verified
Reviewed 2026-09-27The 65,000 cfs daily mean on August 23, 1966 is a USGS-approved record inside a normal flood hydrograph (1,240 cfs the day before, 38,000 and 12,000 cfs the two days after), not a glitch. It is flagged only because no annual peak for that year is in the archive to confirm it.
- Pecos R Abv Canon Del Uta Nr Colonias, NM verified
Reviewed 2026-09-27The Corps copy of this gauge runs about 17% below USGS over 2005 to 2026. The report uses USGS on all but one day.
Warnings (17)
- warning: copy bias Pecos R Abv Canon Del Uta Nr Colonias, NM: The usace_cwms copy runs 16% lower than usgs (median, 1,071 shared days, Feb 13, 2005 to Oct 18, 2026). The report takes 1 days from usace_cwms where usgs is missing, so the level can shift there.
- warning: gap Pecos R At Damsite 3 Nr Carlsbad, NM: 1 gap of 60+ days inside the record (1,339 days in all). Longest: Jan 1, 1941 to Aug 31, 1944 (1,339 days).

- warning: peak conflict Pecos River At Carlsbad, NM: 2 approved USGS daily values exceed that water year's USGS annual peak, in water year 1933 (e.g. 14,500 cfs on Oct 1, 1932 against a peak of 6,890). 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.

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.

Values removed (73)
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.
