Boating survey aims for better river management for recreation
Pitkin County has approved funding for a study that aims to protect recreational flows in the Roaring Fork and Crystal rivers, and how future water development projects and climate change might affect those flows.
At a meeting earlier this month, Pitkin County commissioners approved a recommendation from the county’s Healthy Rivers Board to fund the $19,355 proposal from American Whitewater. The project includes an extensive survey of river users — specifically boaters — about what flows are optimal for certain popular river segments.
Kayakers, commercial river outfitters, stand-up paddleboarders and anyone else who runs local rivers can weigh in with their flow preferences for popular reaches of the Roaring Fork like North Star, Slaughterhouse, Toothache and the river below Basalt. They will also ask about the Crystal River, which gets less recreational traffic than the Roaring Fork, but has some well-known stretches, like the Narrows and Meatgrinder, which are favored by experienced kayakers, and the more accessible reach from Avalanche Creek to the BRB campground.
The lower Roaring Fork is increasingly popular with anglers, but this survey will focus on boating, both commercial and private.
Once American Whitewater determines what flows boaters prefer, the organization will use its “boatable days” tool, which compares the flow preferences to the historic river hydrology to see if and when the flow preferences are met and how that might change in dry or wet years.
“It allows us to actually quantify river recreation opportunities so it can be used to inform water management decisions and understand future impacts,” said Kestrel Kunz, Southern Rockies stewardship assistant for American Whitewater. “We can see how climate change might affect the number of boatable days in the valley.”
According to a report by the Colorado River Outfitters Association, the economic impact of commercial boating on the Roaring Fork in 2019 was $4.8 million. The economic impact statewide was $188 million. But despite the size of its contribution to the economy, recreation is an area often overlooked by traditional water planning and management, according to Pitkin County Healthy Rivers Board Chair Andre Wille.
“Recreation seems to really get the short end of the stick when it comes to streamflow management,” Wille said. “I think water managers in the Roaring Fork area and in a lot of other Western Slope rivers, the water managers are all about irrigation and recreation isn’t really taken into as much consideration as it should be, especially considering the economic impact of recreation and the importance to the citizens.”
About 40% of the headwaters of the Roaring Fork and Fryingpan rivers is sent to Front Range fields and cities — including Aurora, Colorado Springs and Pueblo — through transmountain diversions. When the Twin Lakes tunnel underneath Independence Pass ratchets its intake up or down, it can affect boating conditions downstream on the Roaring Fork and diversions out of the Fryingpan can affect flows on the lower Roaring Fork.
The information collected in the survey could help water managers better plan when and how much water to divert.
“It’s just a chance to get some data from recreation users and it would be nice if water managers would take that into consideration,” Wille said. “There might be other stream management strategies that are beneficial to the Roaring Fork. There might be a better way to manage filling (Twin Lakes) reservoir.”
The survey, which will be available on the American Whitewater and Pitkin County Healthy Rivers websites and local paddling forums, will ask boaters about their skill level, frequency of participation and craft type. The survey will allow boaters to assign use-acceptability ratings to various streamflows and ask them for their perspectives on water management planning. American Whitewater aims to collect at least 150 surveys each from boaters on the Roaring Fork and Crystal rivers.
James Foerster, owner of Aspen-based rafting company Elk Mountain Adventures, said he’s excited to see the county focusing on recreational boating. The company is one of three, along with Blazing Adventures and Aspen Whitewater that run trips on the Roaring Fork.
Foerster’s company runs what they call “adventurous” rafting trips from Cemetery Lane to Jaffee Park in Woody Creek on the Slaughterhouse section of the Fork, as well as “family-friendly trips” from Jaffee Park to Wingo Junction above Basalt on the Toothache section and from Hooks Spur Bridge, near the Fed Ex outlet by Willits, down the river to the Catherine Store Road bridge above Carbondale.
He says guides will change the put-in and take-out locations to adapt to changing flows as the season goes on.
“I think every commercial outfitter would tell you more water is better,” Foerster said. “I think what it really comes down to is the flows we get coming through Aspen in late July and August, they are unsustainable. And the lower Crystal as well, mainly because of diversions and ditches.”
Carbondale-based Lotic Hydrological will develop the survey. The findings will be synthesized and presented as technical reports by December 2020.
