Delta County, CO — Water Intelligence Brief

October 26, 2026 | Colorado River Basin (Upper)

Situation Summary

Streamflows across Delta County's primary water corridors are rising this week, with the Gunnison River at Delta running 923 cfs and the North Fork Gunnison below Paonia at 290 cfs — conditions that signal active late-October runoff and a transition into the off-season storage period. Early snowpack is arriving above median at several stations, offering a modestly positive early indicator for the 2027 irrigation season. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

Five SNOTEL stations monitor snowpack in the upper watersheds supplying Delta County. Conditions as of October 25, 2026:

Where percent-of-median figures are reported, both McClure Pass and Park Reservoir are running well above their respective medians for this date — McClure Pass at nearly three times median and Park Reservoir at 136%. Stations showing 0.0" SWE with no percent-of-median reported (Overland Reservoir) reflect normal seasonal conditions for late October, not below-normal snowpack. Note that 2026 was an extremely early-melt year, with upper-basin stations melting out 4–6 weeks ahead of the historical median meltout date — relevant background as managers assess this season's early accumulation signals.

Streamflow Conditions

All reporting USGS gauges in Delta County's watershed network show rising flows as of October 26, 2026:

The across-the-board rising trend on all active gauges is consistent with late-October precipitation and early snowmelt pulses moving through the system. The Gunnison at Delta and the Uncompahgre at Delta together reflect the combined supply picture for Delta County irrigators. Two gauges — Gunnison near Grand Junction and Plateau Creek near Cameo — have no recent data and represent monitoring gaps in the current picture.
