The Numbers River Run in Colorado on the Arkansas River provides an exciting class IV-V whitewater experience with steep drops, boulder gardens, and tight channels. This section of the river is only suitable for experienced rafters and kayakers due to its challenging rapids and technical maneuvers required. The best time to float this section is typically from late May through early July when the snow melt provides optimal water levels ranging from 800-1200 CFS. Specific river obstacles include the "Staircase" rapid, "Just Enough" rapid, and "Sledgehammer" rapid, all of which require precise navigation skills.

Weather today, Sunny, with a high near 68. North northwest wind 5 to 15 mph becoming southwest in the afternoon.
