Warnings (3)
- warning: gap Eagle Creek Below South Fork Near Alto, NM: 4 gaps of 60+ days inside the record (3,700 days in all). Longest: Jan 1, 1981 to Apr 26, 1988 (2,673 days); Sep 30, 2004 to Sep 29, 2005 (365 days); Oct 4, 2022 to Sep 12, 2023 (344 days).
- warning: peak conflict Eagle Creek Below South Fork Near Alto, NM: 1 approved USGS daily value exceed that water year's USGS annual peak, in water year 2006 (e.g. 87 cfs on Sep 4, 2006 against a peak of 78). 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.

None.
