River Description


Big South is the finest expert run in Colorado. For the first few miles the river marks the western boundery of Rocky Mountain National Park, the rest of the river all the way to the takeout is in the Cache La Poudre Wilderness Area. Big south runs through 12 miles of pristine wilderness with more than a dozen classic Class V, V+, and VI- rapids. The beauty of it is you can have any kind of day you want there. If youÂre there for the scenery and the experience you can easily portage the hardest rapids and have a relatively relaxing Class IV+/V- day. If youÂre there to test yourself and run some big stuff you will have a couple of big technical hair-raising drops to run.

Pinball Wizard, Rock Lobster, Starter Fluid, Barroom Brawl, Bonk, Nitrogen Narcosis, Prime Time Gorge, Pincushion, The Rush, and Tubular Balls are all V to V- at reasonable water levels, and can be run without scouting if you have a good guide to lead you down.

Taco Bobs, and Fantasy Flight are in the Class V territory, but they have some really ugly lines you want to check out before jumping in. Slideways is another good scout, itÂs a classic long and steep Class V studded with big holes.

The truly big Class V+/VI- rapids of the Big South are Cool World, Meltdown, and Double Trouble. Cool World is especially dangerous because it looks like itÂs just another Class IV rapid from the top. Be very cautious until youÂre past it! The final drop of Cool World slams directly into an undercut cliff on river right. Meltdown is a two-step cascade with a sieve at the bottom. ItÂs the hardest rapid to portage, so sometimes it seems like itÂs "almost" easier to just run the rapid! Double Trouble is a big double waterfall. The hole at the bottom is considered by many to be in the top five scariest hydraulics in Colorado, which is saying a lot!

The only real negative to Big South is the short season. The Forest Service keeps the road to the Long Draw Reservoir (the putin) gated until all snow has melted from it, even in a big year there is sometimes only a week or two of water left after the gate finally opens. This leaves you with two unpleasant alternative to bag the big water of early summer. One, you simply hike upriver from the takeout as far as your lungs and legs can carry you. Two, hike down from the source of the Poudre near Trail Ridge Road in Rocky Mountain National Park. This alternative is far easier than hiking up from the bottom, and Trail Ridge Road is guaranteed to be open for the tourists by Memorial Day at the latest, but requires a 4+ hours of shuttle driving.

To get there: The takeout is at the Big South Campground on Co Hwy 14. To drive to the put-in head towards Cameron Pass about a mile until you see a well marked Forest Service sign to Long Draw Reservoir. Head up this dirt road and put-in at the outlet of the reservoir.

We didn't scout this one so I don't remember it too well, nothing went wrong at least!

Starter Fluid

Class - IV+ Mile - 2.6
Rapid Thumbnail Missing

Sweet little waterfall that starts of the goods!

Taco Bobs

Class - 5.0 Mile - 2.9
Rapid Thumbnail Missing
Very different at different water levels. I do know of severe vertical pins at low water. Higher water improves your route options.

Bar Room Brawl

Class - 5.0 Mile - 3.2
Rapid Thumbnail Missing
The river splits around a large rock island. The left channel doesn't go, the right side slams into a wall.

Fantasy Flight

Class - 5.0 Mile - 3.3

The entrance to this waterfall has a right and a left line, I refer to them as ugly and uglier.

Cool World

Class - 5.2 Mile - 3.8

Tricky entrance that gains momentum before launching into and undercut cliff.

Bonk

Class - 5.0 Mile - 4.2
Rapid Thumbnail Missing
Steep drop that pushes into a cliff on river left.

Melt Down

Class - 5.1 Mile - 4.8
Rapid Thumbnail Missing

Two stage drop. The first drop has a hole at higher water that looks like a jet engine. The second drop sieves. Often has wood problem, particularily in the entrance.

Nitrogen Narcosis

Class - IV+ Mile - 7
Rapid Thumbnail Missing

This isn't one of the more distinctive rapids, it kinda blends in with the continuous IV above and below, but is a shade harder.

Prime Time Gorge

Class - IV+ Mile - 8
Rapid Thumbnail Missing

Very fun rapids in a small gorge. Frequently has wood problems.

Double Trouble

Class - 5.1 Mile - 8.8

This is the big daddy of the Big South. Epic hole rides are too be expected.

Pin Cushion

Class - 5.0 Mile - 9.6
Rapid Thumbnail Missing
Pin spot, hard left boof required.

Slideways

Class - 5.1 Mile - 10
Rapid Thumbnail Missing

It's big but straight forward. After 10 miles your definately starting to feel it. The hardest rapid at high water.

Tubular Balls

Class - 5.0 Mile - 10.7
Rapid Thumbnail Missing
The pace seems to quicken after Slideways, not sure exactly which rapid is Tubular balls but do keep an eye out for wood.

The Rush

Class - 5.0 Mile - 11.1
Rapid Thumbnail Missing
Keep and eye out for increasing amounts of wood, you may want to just bag it at some point and start hiking downstream.

Curtain Call

Class - 5.3 Mile - 11.7
Rapid Thumbnail Missing
This has been run at high water, not advisable at any water level. Only for sickos with a lack of good judgement. Waterfalls pouring into sieves. Be sure to start the portage well upstream.

Highway 14

Class - IV Mile - 12

Gage Descriptions

The gauge is visual, there is a painted board located at the Big South Campground (the takeout). It was washed away in 2003 and replaced and needs to be recalibrated. Until then a good guess is that below 2' is low, 2' to 3' is medium, and above 3' is high.

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.

Take Action on Colorado's Right to Float Bill!

3/4/2010
Nathan Fey

This spring, the Colorado Legislature is considering a bill, which helps protect the rights of commercial boaters to float on commercial sections of river, and increases the safety of boaters by decriminalizing incidental contact with private land to portage obstacles. HB -1188 is a good bill, but doesn't go far enough! HB-1188 passed out of the House by a vote of 40-25, and is scheduled to be introduced in the Senate Judiciary Committee for a vote on March 17th. We urge you to contact members of Colorado’s Senate Judiciary Committee and ask them to support HB-1188, and to amend the bill to include all members of the paddling public.
