With rafting starting this weekend, we are stoked for another epic season of adventure! Our outposts in Buena Vista and Idaho Springs open for rafting and all adventures May 10 and offer rafting on the Arkansas River and Clear Creek, respectively. Join us for rafting and other adventures on the Upper Colorado River from our Kremmling outpost beginning the week after, May 17.
The Blue River will also open later in the season, so keep an eye out for our Blue River Express trip, a milder, yet exciting 1/3 day adventure. Because this river requires the perfect conditions to make it runnable, it opened for the first time in several years in 2023.
Colorado Snowpack
Due to another excellent season of snow, Colorado’s snowpack is looking strong this year. Snowpack is a measurement of the snow that has accumulated in Colorado’s mountains during the winter months and that melts to fill Colorado’s rivers and basins. As of April 8th, Colorado’s snowpack was at 114% of average thanks to several late-season storms in March. Snowpack levels are a good indicator of river levels and rafting conditions, meaning we can expect fun and splashy river conditions this year.

River Conditions and Flow
River flow and rates are measured in CFS, or cubic feet per second. This is a measure of river flow and strength. The formula to determine CFS involves multiplying the width of the river by its depth and the speed (determined by flow and gradient). CFS readings are collected at various sections along each river, with different sections potentially yielding different CFS values. Given the unique characteristics of each river, what constitutes a high CFS in one river may be entirely typical in another.

Arkansas River
As of April, the Arkansas River basin held the highest amount of snowpack in the state, with levels at 119% of average. With the Arkansas River already offering some of the best whitewater in Colorado, if not the country, this elevated level will make this river even more fun to rush down this year.

Clear Creek
The Lawson to Idaho Springs portion of Clear Creek is currently running at a lower 71 CFS range, but this bodes well for the season, as the flow will pick up in May. This portion of the Clear creek contains exiting class III-V whitewater just a half hour from Denver. Notable rapids include Meat and Bones, The Zambezi Wave, and Nomad.
