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: gap San Francisco Creek At Upper Station, Near Del Norte: 8 gaps of 60+ days inside the record (13,426 days in all). Longest: Jan 1, 1970 to May 31, 2004 (12,570 days); Nov 8, 2022 to Mar 28, 2023 (141 days); Nov 12, 2020 to Mar 29, 2021 (138 days).

Context (2)

Show 2 notes
  • single gauge Alamosa-Trinchera: 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 San Francisco Creek At Upper Station, Near Del Norte: 4 runs of 30+ days at exactly the same flow: 1.0 cfs for 113 days from Nov 30, 2016; 1.6 cfs for 50 days from Dec 25, 2004; 1.1 cfs for 31 days from Jan 1, 1967. Usually an estimated period (ice, a broken gauge) rather than measured daily flow.

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.
