Warnings (3)
- warning: flatline Rio San Jose At Acoma Pueblo, NM: 19 runs of 30+ days at exactly the same flow: 4.1 cfs for 68 days from Jan 22, 1998; 4.9 cfs for 51 days from Nov 2, 1951; 4.6 cfs for 49 days from Dec 23, 1951. Usually an estimated period (ice, a broken gauge) rather than measured daily flow; the recent run may be a stuck sensor.

Values removed (2)
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.
