Two different numbers, deliberately: Flowing now is raw 15-minute telemetry, provisional and unreviewed. Latest cached reading is the end of the verified daily record. They are never merged, and the verified series is the one the trend is computed on.
The record
Readings come from the weekly-refreshed cache, never fetched live — the date beside the value says exactly how fresh it is. The live gage is one click up.
The water itself
USGS keeps a sensor here. Latest readings, with the last 30 days of daily means beside each. Provisional: not yet reviewed by USGS, and revised when it is.
Fetched 2026-10-15 18:20 UTC from USGS NWIS (site 07105800). The USGS page has the full sensor record; every Colorado sensor site is listed on one page.
