- Rio Brazos At Fishtail Road Nr Tierra Amarilla, NM verified
Reviewed 2026-09-27USGS publishes no daily flow for this gauge in winter: asked directly, the USGS API returned no values from November 2023 through March 2024, and the archive has almost none for December to February in any year. The gauges on this high snowmelt stream are likely iced over in winter (inferred, not stated by USGS). This is the only gauge on the page, so yearly means are empty.
Warnings (2)
- warning: seasonal Rio Brazos At Fishtail Road Nr Tierra Amarilla, NM: No record in Dec–Feb most years: the gauge reports seasonally, so yearly and some monthly means are missing or cover only part of the year.
- warning: no yearly Rio Chama: No year has the 45 weeks a yearly mean needs (most has 38), so the Year view is empty for this segment. Use Month or Week.
