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.
