River Description


In 2003 the mile above Hellum's Waterfall was cleaned out and 1st descented. This has doubled the length of the run! The new top 1/2 has a different character, it is not gorged up and the inbetween stuff is easier while the named drops are bigger. The first of these is Gun Shy (Class V), 4 big ledge drops back-to-back with big holes and undercuts on both sides. Shortly downstream is Harvey Wallbanger (Class V), this is one ugly rapid and destined to be carnage central for the Source. It already has a reputation! There is a summer home sitting right next to this rapid, you must tresspass to scout so be very stealth. Just downstream is Hellum's Waterfall. The left channel will bounce down a technical sluice before dropping off a 10' fall and the right channel is a straight shot at a 15' vertical. Both options have rocky landings, and both have been done without pitoning. At this point you are at the old put-in. If this is your 1st time down it is impossible to remember every single cascade in the lower section. So concentrate your scout on the big cascade near the bottom - Dead Hiker Falls. DeForrestation Rapid, the first below Hellums, cleaned up in 2003 and no longer requires a scout. Every other rapid can be run on the fly. At medium to low flows you can expect a few minor pins in-between the major rapids, this run is really abusive to your boat. Think "manky-town". At high water (400cfs+) the rocks are nicely padded out but the creek starts to push into the trees and the holes get evil.

Do all hiking and scouting from river right because there is private property on the left.

Pics of the Upper Source can be found at Brian Adkins Webshots album, and pics of the Lower Source on Mike Albrecht's Webshots album.

To get there: Drive south out of Nederland towards Central City. At the edge of town turn right on the road to Eldora Ski Area, 1/4 mile down the road go straight instead of left to Eldora. After driving through a small town the pavement will end, another mile or so down the dirt road you will come to a fork in the road. To the right is the Fourth of July Road which takes you to the put-in, to the left is the Hessie Road and the take-out.

To get to the new put-in drive about a mile past Hellum's Waterfall, which is very obvious from the road, to a campground on the left. The campground is an undeveloped flat grassy field of about an acre in size with a couple of fire rings scattered about. The creek is only 50 feet from the road and mellow Class II at that point.

The takeout is 1/2 mile up the left fork, Hessie Road, or you can boat Class II(with wood hazards) down to the fork of the road. This latter option is a good idea for low clearance cars.

Rapid Descriptions

Put-in

Class - II Mile - 0
Rapid Thumbnail Missing
Put-in at a nice flat grassy field about an acre in size with a few fire rings scattered about.

Gun Shy

Class - 5.0 Mile - 0.5
Rapid Thumbnail Missing
A series of 4 ledges back-to-back. The top drop has a must make boof to the right at the entrance, and has a sticky hole at the bottom with undercut rocks on both sides. The next 3 ledges are pretty simple.

Harvey Wallbanger

Class - 5.0 Mile - 0.75
Rapid Thumbnail Missing
The current slams hard into the river right cliff in this tricky drop. The move is a right to left scramble at the last moment. This rapid has become the scene of the vast majority of the carnage on the Source.

Hellums Waterfall

Class - 5.0 Mile - 1
This is a 15' fall that lands on a pile of rocks. In 2003 it was run down the small river left channel regularily, the line looks bad but no-one pitoned.

Kickstart

Class - IV Mile - 1.1
Rapid Thumbnail Missing
An easy slide with a left turn halfway down.

the willows

Class - IV Mile - 1.2
Rapid Thumbnail Missing
Make sure to enter the river right channel into the willows directly after Kickstart. Ever been whipped by willows? This section has gotten seriously overgrown in the past few drought years with no flood water to scour out the overhanging vegetation so I've upgraded it to Class IV.

DeForrestation Rapid

Class - 5.0 Mile - 1.3
This rapid changed in 2003. It is easier and safer than before, the line is still a boof left but the broach rock at the bottom moved several feet out away from the bottom. Be heads up for this drop after passing under the second foot bridge. The entrance rapid (IV-)is manky as hell.

1st Gorge

Class - IV+ Mile - 1.4
Rapid Thumbnail Missing
After some bony busy water there is a good 2 or 3 boat eddy on river right where you can boat scout the entrance to Slot Machine.

Slot Machine

Class - 5.0 Mile - 1.5
At about 3' wide this is the tightest drop on the run. There is a flat piton rock in the landing zone, but a good boof stroke is difficult. You can eddy out on river right 50' downstream.

busy water

Class - 5.0 Mile - 1.6
From here to Dead Hiker Falls it is continuous IV to V slides, ledges and boulder gardens. Keep on your toes and watch out for wood.

Dead Hiker Falls

Class - 5.0 Mile - 1.8
Rapid Thumbnail Missing
This is the biggest cascade on the river. The second most likely rapid, after Harvey Wallbanger, to kick your ass.

more busy water

Class - 5.0 Mile - 1.9
Rapid Thumbnail Missing
Continuos IV to V slides, ledges, and boulder gardens. About 100 yards below Dead Hiker Falls there is a short slide with an large eddy river right. Downstream, just after crossing under a large log that spans the whole stream, is a tricky little boulder drop that deserves a scout.

Cheese Grater

Class - III Mile - 2
Rapid Thumbnail Missing
Cheese Grater is a metal hazard 10' upstream of the takeout. Takeout at the bridge crossing the creek or continue downstream another 1/4 mile through Class II with wood hazards to the fork of Hessie Road and Fourth of July Road.

Mank City, Colorado.
When we get a decent snow year, she'll go for a few weeks.
This run has some tricks.
Take your time to 'sus it out.

Gage Descriptions

The Colorado Division of Water Resources gauge is Middle Boulder Creek near Nederland.

Or: call Watertalk: 303/831-7135 Division 1 Station 94 - Middle Boulder Creek at Nederland.

Low: 150 - 300 cfs
Med: 300 - 450 cfs
High: 450 cfs and up

*Early season readings are deceptively high due to lower elevation snow melt below the run. However, late season readings are mostly based on the actual flow of the reach. So while a reading of 250 in May resulted in a bony run, a reading of 250 will be a well padded flow in July.

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.
