River Description

Colorado road side mank at its finest, with a unique touch. 

This tall roadside canyon comes complete with multiple put-in and take-out options for variable spice factor; boasting hairy cascades and gnarly ledges to keep you on your toes the whole way down. 

After driving three miles towards Allenspark, from Lyons on highway 7 you'll come around a corner and see a roughly five foot spout drop, this is 1in5.  

Use the large dirt pull off next to the rapid as a take out.  A large cotton wood tree acts a good marker from river level, if you wish to take out above this one.

It's a good idea to scout this one. Safety is recommended.

The main line on 1in5 is off the left, a good right stroke will bring you home. This drop becomes substantially meatier above 400 cfs. The right side acts as a potential sneak at these levels. If water is running over the rock on river left, it may be a good idea to take out above.

This rapid is ideal for lapping. Get creative with put in methods.                        

It is important to be aware of the cave on the river right side of the pool, created by the boulder that creates the two channels. Too date no person has been stuck in that room, several boats have though. They where in there for quite awhile.

For the put in, drive about a mile and a half up the road, coming around another bend you'll see Jihad, a steep and manky drop, with an out of play log in the middle of two pinches.  Use the first pull off on the right directly adjacent to the drop. Gear up and scout. 

There are several put ins depending on how high you want to walk up. Hiking up the shoulder will bring you to a very steap cascading section, barreling around a sheer corner: The Narrows. If this looks like your jam, keep hiking. If not, put in below all that nastiness. Be aware, put in spots are loose at best.

The top of the Narrows is marked by a river wide ledge drop with a dynamic lip.  This is the one and only, Hot Donna. After running this you're commited to the rest of the section. Find a good spot above to get in and send'er on down. Hot Donna is run off of the left with a big right boof, it is easy to get eddied out on the left after landing.

Next is White Lightening, run down the left; this is followed quickly by two back to back boulder jumbles. Run the first on the left, then hussle back right for the second. Lastly, slip down the left side final pile, dodging a hidden piton rock. Catch the big eddy on the right and breathe a sigh of relief. 

Don't let your gaurd down just yet, you still have a series of class IV+ drops, and then Jihad. The top of Jihad is run down the left tongue, despite what you might think, you won't piton.  The more left you come in at the top, the less difficult the move at the lip will be. Move across the pool toward the right, mind the log.  

Run the second tier from right to left, and take solice in knowing the sketchest part is behind you. The rapids from below jihad are all fun IV+ until 1in5. This section is easily routable with someone who knows the lines. Don't forget to keep your eye's peeled for the 1in5 cottonwood tree.

This run is at the most two miles from the top of Narrows, so lapping is typicaly a popular idea.

As of 2017, several groups have put in above Narrows, but below the confluence, and run through 1in5. There are several technical class IV/V drops in this section, and more than a few log portages.

Have fun, be safe, and don't forget to keep your eyes peeled for wood.

Gage Descriptions

The gauge for the South St. Vrain is primarily visual. (1in5)

Basically, the flow for SSV is determined by taking the South Saint Vrain in Lyons minus the North Saint Vrain below Buttonrock Reservoir.

150 CFS is the bare minimum

250 ~ 400 CFS is good

400~600 CFS is high, narrows not typicaly run

750 CFS, highest decent, jihad to 1in5

Directions Description

The entire run is next to HWY 7, about three miles upstream of Lyons.

The last class V drop, 1in5 is an obvious spout visible from the road.  Use the large dirt pull off as a take out.  A large cotton wood tree can be seen from the river, and acts as a good marker if you wish to take out above 1in5.

For the put in, drive a mile and a half up the road, coming around another bend you'll see Jihad, a steep and manky drop with an out of play log the middle of two pinches.  Use the first pull off on the right directly next to the drop.

Colorado Parks & Wildlife to Require Hunting or Fishing License at River Access

Kestrel Kunz

In an unexpected and strategic move by Colorado Parks and Wildlife (CPW), a Colorado hunting or fishing license will now be required to access State Wildlife Areas and CPW-leased State Trust Lands (effective July 1, 2020). Many of these affected areas have historically been used for paddling, hiking, rock climbing, mountain biking, camping, and other non-consumptive recreation uses. CPW's press release stated that "This rule is aimed at curtailing non-wildlife-related use of these properties", and while we understand the need to increase revenue to support management of these areas, we have a few concerns with this strategy. On July 1, American Whitewater, Colorado Mountain Club, and multiple other organizations submitted a joint letter to CPW Commissioners requesting that they reconsider the new Rule and find a more practicable and sustainable method for collecting fees for these areas.

Voluntary River Closure Proposed On the Slate River (CO)

Kestrel Kunz

Crested Butte CO - Alleged disruption to a Heron Rookery and concerned private landowners have led to a "Voluntary Closure" of the Slate River from the Gunsight Bridge to the Town of Crested Butte between March 15 and June 21 for the 2019 season. The Slate River between Oh Be Joyful Campground and Skyland Bridge, a 10.5 mile stretch, provides an incredibly scenic and unique flatwater paddling experience in the Gunnison Valley. The Voluntary clsoure is a product of the Slate River Floating Management Plan, created by a Working Group convened by the Town of Crested Butte and the Crested Butte Land Trust. The Working Group was created in direct response to pressure from the local community including conservationists and private landowners adjacent to the river, who are concerned that a recent increase in boating activity is disturbing a Heron Rookery that straddles the Slate River.

AW Comments on Colorado Nat'l Forest Wilderness Process

Kestrel Kunz

Today, September 5, marked the close of the public review process for the DRAFT Wilderness Evaluation Report. The Evaluation Phase is the second step of 4 different steps required in the assessment of lands that may be suitable for inclusion in the National Wilderness Preservation System (NWPS). American Whitewater thoroughly reviewed the DRAFT Wilderness Evaluation Report and submitted our comments to the Forest Service on September 4, 2018. Overall, we found that key paddling reaches throughout the GMUG area were greatly under-represented in the Polygon narratives and thus weren't acknowledged as contributing factors to the Polygon's respective Wilderness Ratings. We let the Forest Service know this, highlighting specific paddling reaches that should be added to each Polygon and which Polygons we believe should have a higher Wilderness Rating based on the high-quality recreation opportunities that each area has to offer. 

Please stay tuned as we continue to report on the GMUG Land Management Revision Process and in the meantime you can learn more about the GMUG here. (Photo of Josh King by Nick Spitzer)

A Successful River Cleanup on the St. Vrain (Lyons, CO)

Kestrel Kunz

On Sunday, nearly 50 people gathered on the banks of the St. Vrain River to pick up trash from the water and the shoreline. We started the day off with Hotbox Roasters coffee and donuts, and a few words about River Stewardship – the common cause that brought us all together. We found bedframes, rusty nails, lawn chairs, car doors, plastic water bottles, candy wrappers, fast food containers, and it doesn’t stop there. Our findings are likely a combination of leftover debris from the floods, illegal waste dumping along the river, and built up trash from years of careless passers-by. Thank you to all those that came out for the river cleanup! American Whitewater depends on our affiliate clubs, members, and dedicated volunteers in order to tackle our many River Stewardship projects.
