Character

About 10 miles. Red Gore Canyon ends at Yarmony Rapid, then the river slows toward Rancho del Rio.

Watch for

Yarmony Rapid is Class III, and Class IV at very high water. Some land on the north side is private until the river leaves Red Gore Canyon. Wind can slow the flat water below the canyon.

The Kremmling gauge is upstream of this stretch, so flow here may differ from the reading.

Snowpack

Upper Colorado mainstemEarly season

Snow water equivalent 0.4 in. Early season — median too low for a meaningful %.

Outlook indicator, not a flow forecast. Spring temperatures, rain, soil moisture, dust on snow and reservoir releases also matter. NRCS SNOTEL data as of Oct 31, 2026 (provisional).

Trip reports

Wavetrain is an early build. Flow readings are USGS provisional data and may be revised. Runnable ranges and run details are drafts for paddlers to review. Permit dates and rules come from the agency pages linked on each permit and can change. Snowpack figures come from NRCS SNOTEL stations, are provisional, and are grouped into basins by watershed, so they may differ from official NRCS basin reports. Nothing here replaces scouting, local knowledge or a conversation with a nearby outfitter.
