Current SE Utah Slot Canyon Conditions

The CCA Canyon Conditions tool monitors Zero G, Eardley, Cable Canyon, Alcatraz, Angel Cove, No Kidding, Leprechaun, the Hog Canyons, Poe, Upper Greasewood, the Black Hole, North Fork Iron Wash, Constrychnine, the Squeeze, Entrajo, Pool Arch, and Woody Canyon.

How the pool-refill estimates work

Radar rainfall is averaged across each canyon’s watershed. The model then estimates watershed runoff using canyon-specific curve numbers and compares that runoff with estimated empty-pool storage based on technical-section length and pothole morphology. Intense-rain coverage and storm duration are used as additional confirmation.

What the results mean

  • Partial refill possible: Some new water may have reached canyon pools.

  • Major refill possible: Modeled runoff approached or exceeded estimated empty storage.

  • Pools may be full: The storage target, intense-rain footprint, and storm-duration requirements were met.

  • Strong flush likely: Modeled runoff substantially exceeded the estimated pool-storage target.

Safety limitation

This tool reports recent rainfall and modeled pool-refill potential. It is not a flash-flood forecast, route-opening notice, or substitute for current National Weather Service forecasts and local land-manager closures.

See recent Utah slot canyon conditions based on radar rainfall, watershed runoff modeling, and canyon-specific pool-storage estimates. This tool tracks 17 technical canyons and identifies storms likely to produce partial refill, major refill, or flushing. Additional canyons will be added in future versions.

Conditions are modeled from weather radar and watershed characteristics rather than direct field observations. Results can help canyoneers identify which drainages received meaningful rain, but they do not represent current flash-flood clearance or guaranteed pool depths.
