Colorado rafters brace for drought

Colorado rafting companies are heading into the 2026 season with one of the thinnest snow years on record and plans for fewer, shorter or shifted trips. (denverpost.com) The snow that feeds Colorado rivers is measured as snow water equivalent, or how much liquid water sits in the mountain snowpack. The United States Department of Agriculture said Colorado’s statewide snow water equivalent was 22 percent of median on April 9, after peaking weeks early in late February to mid-March. (nrcs.usda.gov) That early melt is already changing the river calendar. The Natural Resources Conservation Service said snowmelt that usually supports April-through-July runoff is entering rivers earlier, which can make spring flows look decent while shrinking total summer volume. (nrcs.usda.gov) For rafting outfitters, the risk is not just lower water but a shorter season on some runs. The Denver Post reported operators are weighing route changes, different launch logistics and the possibility that some stretches may not stay runnable through the usual summer window. (denverpost.com) Several outfitters are using 2002 as the comparison year because that drought hit both water levels and bookings. A Colorado State University archive describes Arkansas River rafting at about 200 cubic feet per second during the 2002 drought, compared with a more normal 500 cubic feet per second. (archives.colostate.edu) Federal research later found the 2002 drought dragged Colorado summer streamflows far below normal. A United States Geological Survey report said mean summer streamflow in 2002 ranked at an average percentile of 7.6 relative to 1978 through 2002 conditions statewide. (usgs.gov) The rafting business feels those drops quickly because many trips depend on a narrow band of flows: too little water exposes rocks and forces boat changes, while too much can close runs for safety. University of Colorado Boulder said low snowpack can compress rafting and fishing seasons and make staffing and reservation planning harder for river towns. (colorado.edu) The state’s snow survey program exists partly to help managers and recreation businesses make those calls before runoff arrives. The Natural Resources Conservation Service says its snowpack and precipitation network is used to produce streamflow forecasts for water managers, reservoir operators and recreationists. (nrcs.usda.gov) Low water does not automatically trigger a closure, but Colorado rules let law enforcement issue river advisories or restrictions when conditions create safety hazards. State boating regulations say officers can order partial or full use restrictions when runoff, water levels or other conditions threaten human life and safety. (justia.com) Some outfitters are still holding out for late snow and spring rain. But with Colorado’s snowpack already down to about one-fifth of median in mid-April, many companies are building their 2026 season around a river year that could peak early and fade fast.
