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.
What this gage meters
This is not a natural stream record. The Hoosier Pass Tunnel moves water from Blue River headwaters (Div 5) into Montgomery Reservoir, Middle Fork South Platte (Div 1), operated by Colorado Springs Utilities (Continental-Hoosier project) — so this record is a ledger of those deliveries. Trends here reflect operational and demand decisions, not the basin's hydrology, and the basin trends page marks it accordingly (⇆). All of Colorado's curated transbasin diversions are collected at /transbasin.
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.
Annual flow & trend
Chart: annual mean flow at Bemrose-Hoosier Diversion near Hoosier Pass, water years 1957 to 2026. The measured record is no trend at 0.19 cubic feet per second per decade. The underlying yearly values are available as a CSV download linked at the top of this page.
This gage measures the Hoosier Pass Tunnel, water carried across the Continental Divide. It is taken from Blue River headwaters (Div 5) and delivered to Montgomery Reservoir, Middle Fork South Platte (Div 1) — so what this gage reads leaves one river basin for good and arrives in another.

Provenance
DWR station abbreviation BEMHODCO; recorded station name “BEMROSE-HOOSIER DIVERSION NEAR HOOSIER PASS, CO”; operated by USGS. Daily flows from the DWR HydroBase snapshot plus CDSS REST updates, refreshed on the weekly cycle. Trend statistics are Mann-Kendall (Hamed-Rao corrected) with Sen's slope in native cfs, the same numbers as the basin Trends tab.
