Lower Boulder Canyon is currently TOO LOW to be paddled and you could find yourself bottoming out on rocks. Paddlers are advised to exercise caution with streamflow levels at 81cfs, about -85% below the average runnable rate of 550cfs. We recommend paddling this section of the Boulder Creek between a bare minimum of 250cfs and a high of 1300cfs.

This class IV- to V- journey is accessible from 2 different boat launch points along the Boulder Creek. Paddlers should prepare for some fun paddling along this run. Streamflow levels and subsequent run conditions for Lower Boulder Canyon are sourced from the nearby USGS streamflow gauge at Boulder Creek At Mouth, Near Longmont, Co..

As a Boulder local, I have a love hate relationship with Boulder creek.  It's Boulder's main artery and so much fun at elusive high flows, but so rocky and poor quality at low flows.  Why people insist on dropping everything to run this stretch of "almost" whitewater at 200 cfs is beyond me, especially since there are almost always better options with just a little extra driving.  Maybe it's the hords of slightly intoxicated college girls in bikinis tubing through the sticky whitewater park in town.  For me, the run gets good when the tubing ban goes into effect for the creek (about 500 cfs). Weather on the river today will be isolated showers and thunderstorms after 2pm. partly sunny, with a high near 86. light and variable wind becoming west southwest 5 to 9 mph in the afternoon. chance of precipitation is 20%.

Forecast Discussion

000 FXUS65 KBOU 161035 AFDBOU Area Forecast Discussion National Weather Service Denver/Boulder CO 435 AM MDT Thu May 16 2019 .SHORT TERM...(Today and tonight) Issued at 435 AM MDT Thu May 16 2019 The upper ridge axis has moved to eastern Colorado with an increase in southwesterly flow aloft over the majority of the state. Compressional warming from the southwest winds across the mountains of central Colorado should give Denver and the northeast Colorado plains a few degrees of warming over yesterday. It should be the warmest day of the week, even as high level clouds increase in thickness through the afternoon. High based showers are expected to develop through the afternoon that move from the mountains and foothills out across the plains. Any rainfall amounts should be light, but gusty winds up to 40 mph will be the primary threat from the storms. Evening showers on the plains could last until almost midnight, but should be out of the Denver area by 6 PM. As the southwest flow aloft strengthens over the state tonight, the airmass will continue to moisten and the next round of showers looks like it will be moving into the mountains around sunrise Friday morning. Temperatures overnight will be mild due to the cloud cover and continuing southwesterly flow pattern. Snow melt runoff should continue to be mainly influenced by the warm temperatures, and should not pose any problems through the next 24 hours. .LONG TERM...(Friday through Wednesday) Issued at 435 AM MDT Thu May 16 2019 Rather energetic ptrn for mid May will be in place the next several days. First system along the West Coast will move quickly into the Great basin by Fri morning and then across the area by Fri night.

Expect showers and a few storms will develop over the mtns in the morning and then move across the plains during the aftn. Sfc pattern over nern CO will be complicated by early Fri aftn.
