Summary

This class III+ to IV+ journey is accessible from 2 different boat launch points along the Arkansas River. Paddlers should prepare for the 10 class III+ to IV+ whitewater rapids along this run. Streamflow levels and subsequent run conditions for Numbers are sourced from the nearby USGS streamflow gauge at Arkansas River Below Granite, Co.


The Numbers is a classic stretch of class IV whitewater on the Arkansas River upstream of Buena Vista.  When the water is high and the sun is out, this is about as good as class IV boating gets in Colorado.  At low and medium flows expect to see a lot of kayakers and rafters playing their way down the river.  At higher flows, you may have the run all to yourself, even on a weekend. Weather on the river today will be a 10 percent chance of showers and thunderstorms after 1pm. partly sunny, with a high near 64. west southwest wind 5 to 10 mph becoming south southwest 10 to 15 mph in the morning.

Forecast Discussion

000 FXUS65 KPUB 161053 AFDPUB Area Forecast Discussion National Weather Service Pueblo CO 453 AM MDT Thu May 16 2019 .SHORT TERM...(Today and tonight) Issued at 453 AM MDT Thu May 16 2019 More clouds and enhanced westerly winds into the surface lee trough have kept temperatures warmer tonight across southern CO with . readings in the 50s to lower 60s across the plains and 40s for the valleys and 30s across the mountains. With increasing southwest flow ahead of the incoming system along the CA coast today, should see another warm day across southern CO with temperatures pushing into the 90s across the plains, and 70s to near 80 across the valleys, and 50s and 60s for the mountains. This will continue the snow melt with increasing flows and rising water levels on mountain creeks and streams. Wouldn`t be too surprised to hear of some of the smaller creeks reaching bankfull later today based on recent trends in stream gages out west. Meanwhile, with increasing winds today, expect critical fire weather conditions across much of the plains during the afternoon. Fortunately, the recent green up has put fuels in the non-receptive category according to land management agencies, so no fire weather highlights are anticipated. Isolated afternoon thunderstorms will still be possible across the mountains today with model soundings showing a slight increase in mid/high based moisture ahead of the west coast system. PV fields show a weak wave ejecting into western CO ahead of the main impulse rotating into NV and western UT later tonight. However with rather dry low levels, main threat will be localized erratic gusty winds and lightning but little rainfall. While focus area will likely be along the Continental Divide, high res models and the NAM12 indicate another potential focus along the Palmer Divide/Pikes Peak region this afternoon. Wouldn`t be too surprised to see gusts exceed 50 mph from any high based showers as they move into the adjacent lower elevations late this afternoon through this evening. Otherwise, convection should wind down this evening, except along the Continental Divide where increasing moisture ahead of the ...
