What this gage meters
This is not a natural stream record. The Treasure Pass Ditch moves water from Wolf Creek, San Juan basin at Wolf Creek Pass (Div 7) into Rio Grande basin (Div 3) — 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.
