Arkansas River Basin Snowpack Update December 2018

Arkansas River Basin Snowpack Update

Arkansas River Basin Snowpack Above Average

The snow is piling up in Colorado, which could mean high water on the Arkansas River next summer. Rafting season is still five months away though, so it’s way too early to make predictions about the 2019 Colorado whitewater rafting season. Nonetheless, it is nice to be ahead of the curve.

Statewide snowpack for Colorado is 112% of normal. The Arkansas River Basin snowpack is 144% of normal snow water equivalent (SWE) and 247% SWE compared to this time last year. Key SNOWTEL sites in the upper basin are even better. Brumley is reading 159% of normal SWE and Fremont pass is 151% of normal SW (data from the USDA Natural Resources Conservation Service). Reservoir storage is still in good shape and the long-term forecasts are favorable for what could be a bounce-back year on the Arkansas River. Last year was one of the lowest on record.
