River Description


Upper North Saint Vrain Creek is the the only major canyon in the Front Range that hasn't had a highway or railroad blasted up it. It is quite a long day with 10+ log portages and numerous Class V and V+ rapids. Not for the meek, it has been said that UNSV is a place to take your enemies, not your friends!

Be on a constant look out for wood, running blind corners is not a good idea.  When in doubt, scout.

There are 3 distinct sections with markedly different personalities as you work your way toward Buttonrock Preserve.

The first zone is the Murkwood Section; manky Class V with an abudnace of wood through out. Although the rocks are nice and round, the pinball nature of the rapids combined with the wood make this upper section a difficult place for some to enjoy.  If this happens to be the case with you, walking back out here, as the car is still very close, can be a good idea..

Cascade #1(V) starts off about 50 yards below the put-in. It's not so much unrunnable as it is ugly, manky, and un-fun-able. I usually portage (river left past the no tresspassing signs) straight from my car to just below the last ugly drop. The run-out of Cascade #1 is actually a lot of fun. About a ½ mile downstream is Cascade #2, which is a pretty sweet boulder choked rapid.  The Murkwood section continues on for about 3 more miles, the gradient gradually petering out. There is a lot of wood in here, and it moves around a lot at high water. Runs before and after the peak will have wood portages in different rapids.

This second section is a 4 or 5 miles Class III strech, through some very dramatic terrain, you will see huge ridges of rock coming down from the top of the canyon to river level. Your instincts tell you that there is going to be a huge rapid where the river and the ridge meet, but there isn't.

The third and final zone is called the California Section.

The rapids transition from manky broken rock to smooth granite bedrock. You'll know when to get out and scout as the gradient will pick up dramatically. The California Section is characterized by bedrock pool-drop rapids, one Class V right after another, all in a spectacular smooth granite canyon so unlike much of Colorado. There is a jeep trail in this section, on river left, greatly helping scouting and portaging. The first significant drop splits around a giant boulder and into undercuts on both sides, most choose to portage. The rapid just below the steapest section is tricky to portage(run the entrance and portage the main drop river left). There is a sieve at the bottom of this steep rapid, dangerous at low water.

After this the California Section proper is done, the difficulty mellows out to Class III/IV, but the beautiful bedrock rapids remain. There are a few more log portages in this section, and one or two Class V- drops mixed in, before you get to The Slot. This is pretty much the last drop of the run, there is a left and right slot, and you really want to get to the left slot.

Formerly the paddle across Buttonrock Preserve was illegal, but thanks to the hard work of some local boaters there is a two year test of allowing whitewater paddlers across the reservoir! So be on your best behavior! Do not linger on the reservoir, paddle directly across, portage the dam and put in below as quickly as possible. Make your presence as minimal as possible!

After you have put in below the very clear outflow jet, paddle several more miles to your car. Be heads up for a 15 ft dam about 2/3 of the way down.  It has been run, but is easy to portage. 

As of 2017 there have been only two complete decents, and wood was very prominent. This section comes highly reccomended, especially for someone looking for a bit of adventure style boating.  

 

To get there: From Lyons head up Hwy 36 towards Estes Park. Look for small County Road 80 on the left and head up that until you get to the gate for the Buttonrock Preserve. Park at the far end of the lot away from the gate and leave a car that doesn't scream "paddler", this will help keep the rangers from looking for you. Head back down to Lyons and up Hwy 7 past the junction with Hwy 72. A few miles past Allenspark you will dip into the North Saint Vrain Valley, put-in at the bridge where Hwy 7 crosses the creek. Actually you should start your run by discretly portaging past the no-tresspassing signs on river left until you are below Cascade #1.

There is an alternate put-in option, that requires hiking down Bright Trail: 1700 ft dropped in 1.5 miles.  So be prepared for steep terrain, a map with details regarding the trail can be found under the photos tab. 

Trail meets the river about two miles above the Cali Section

Rapid Descriptions

Peak To Peak Hwy

Class - IV Mile - 0
Rapid Thumbnail Missing
Put-in and run some bony Class IV with the intention of getting out real soon, or just start a stealthy portage down river left...

Cascade #1

Class - 5.3 Mile - 0.1
Rapid Thumbnail Missing
Huge and ugly.

Cascade #2

Class - 5.2 Mile - 0.4
Rapid Thumbnail Missing
Long and technical, about half as steep as the first cascade. Still not to be taken lightly.

Rock Creek

Class - IV Mile - 2.2
Rapid Thumbnail Missing
Rock Creek comes in on river right, this is about the end of the Murkwood Zone. Expect less wood and mellow Class III for several miles.

Cow Creek

Class - III Mile - 3.8
Rapid Thumbnail Missing
Cow Creek comes in on river left.

California Section

Class - 5.0 Mile - 6

The river character transitions to smooth bedrock and the gradient starts to pick up progressively.

Steep Section

Class - 5.2 Mile - 6.6
Rapid Thumbnail Missing
The most steep and burly part of the California section, big rocks and big holes with clean lines. This is the signature drop of the California Section.

Clam Shack

Class - 5.3 Mile - 6.8
Rapid Thumbnail Missing
At the bottom of the "steep and burly" bit you need to eddy out upstream of the bridge. Just below is Clam Shack, a short but big V+ with undercuts.

Significant Rapid

Class - 5.1 Mile - 7

Worthy of a scout. Below Clam Shack are some great rapids and stout holes. When you come to a big horizon line scout on the right. The rest is read and run until the next bridge.

Eye of the Needle

Class - 5.0 Mile - 7.2
Rapid Thumbnail Missing

Fairly easy line, but very nasty consequences. Scout from the right,portage on the left.  The rapid is marked by a very sharp right hand bend in the river. 

The Slot

Class - 5.1 Mile - 9

There is a left slot and a right slot, avoid the right slot...

Low Head Dam

Class - III+ Mile - 9.2
Rapid Thumbnail Missing
Run it anywhere, it's good to go. From this point on you are paddling illegally...

Ralph Price Reservoir

Class - I Mile - 9.5
Rapid Thumbnail Missing
One and 3/4 miles of uphill paddling.

Button Rock Dam

Class - I Mile - 11.2
Rapid Thumbnail Missing
If you manage to get past the rangers carry down the left side of the dam, not the sluice - which is further to the left. The outlet of the dam shoots water out Gauley style, big 40 foot roostertails where it hits the water.

Longmont Reservoir/Dam

Class - IV Mile - 12.8
Rapid Thumbnail Missing
After one and 1/2 miles of fun Class III/IV portage the dam on the right.

The Takeout

Class - III Mile - 13.25
Rapid Thumbnail Missing
Congratulations!

Land and Water Conservation Fund Secures Access to Upper Colorado River

5/8/2019
Hattie Johnson

A bill to fully fund the Land and Water Conservation Fund (LWCF) was introduced last month by Colorado Senator Cory Gardener and West Virginia Senator Joe Manchin and cosponsored by Colorado Senator Michael Bennett. If passed the bill would provide $900M annually for projects protecting natural, cultural and historic resources. Existing funding from the LWCF recently enabled the transfer of two important river access points on the Upper Colorado River. The State Bridge and Two Bridges parcels were owned by Eagle County and had been improved - boat ramps, parking, restroom/changing facilities - by the Eagle County Open Space program with coordination and management support from the Bureau of Land Management (BLM). This land transfer will protect public access at these locations in perpetuity.

Voluntary River Closure Proposed On the Slate River (CO)

11/2/2018
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

9/5/2018
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)

6/7/2017
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.
