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.
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 Ewing Ditch Bypass, water years 2026 to 2026. The measured record is insufficient data at 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 Ewing Ditch, water carried across the Continental Divide. It is taken from Piney Creek, Eagle River headwaters at Tennessee Pass (Div 5) and delivered to Tennessee Creek, Arkansas basin (Div 2) — so what this gage reads leaves one river basin for good and arrives in another.
The two ends: Ewing Ditch (source, on South Fork Eagle River); Ewing Ditch (receiving, on South Fork Eagle River)
