Snowpack

Lower Colorado (UT)Early seasonDam-regulated

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

Upstream aggregate — combined Upper Colorado + Green River snowpack.

Dam-regulated: Flaming Gorge Dam. Flows on this river also depend on reservoir releases — snowpack alone does not determine flows. Reaches this stretch through the Green River upstream.

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.
