What this gage meters
This is not a natural stream record. The Ewing Ditch moves water from Piney Creek, Eagle River headwaters at Tennessee Pass (Div 5) into Tennessee Creek, Arkansas basin (Div 2), operated by Pueblo Board of Water Works — 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.
