From The Aspen Times (Jason Auslander):

Pitkin County will begin construction next week on the latest fix to a whitewater park on the Roaring Fork River in Basalt that some said was too dangerous during high water last summer, sources said Wednesday.

“The primary goal of the adjustment is to improve high-flow navigation from runoff,” said Quinn Donnelly, an engineer with River Restoration of Carbondale, which designed the park. “(High water) was creating big holes and people were flipping.”

Contractors next week will begin altering two man-made concrete wave structures in the riverbed to make them less difficult to navigate during high-water conditions, Donnelly said. Crews will move around boulders and create ramps to better flush water through the area and create a wave-train, he said.

“The goal of this winter’s work is to strike a better balance between the fun surfability of the waves and their high-water navigability,” Pitkin County Healthy Rivers and Streams Board Chairman Andre Wille said in a news release Wednesday. “The end result will be wave features that are easier for river runners to bypass at high flows.”

Despite repeated requests Wednesday for how much the project will cost and where the money will come from, a spokesperson for the Pitkin County Healthy Rivers and Streams Board declined to release it. The park was initially built for $770,000 with Healthy Rivers funds, though it’s not clear how much has been spent since then to tweak it.

This winter’s project will mark the second time the whitewater park has had to be re-engineered because of safety concerns.

#Colorado rafting team falls short in second attempt at speed record down the #GrandCanyon — The Colorado Sun

The U.S. Rafting Team has enlisted three veteran Grand Canyon guides in a mission to set a new speed record for descending the Colorado River’s 277 miles through the canyon. The team tested a new raft design last month on the Ruby Horsethief and Westwater canyons, rowing from Loma to Utah’s Dewey Bridge in about nine hours. (Robbie Prechtl, special to The Colorado Sun)

From The Colorado Sun (Jason Blevins):

They finished in 37 hours, 55 minutes, missing the 34-hour, 2-minute record set by kayaker Ben Orkin in 2016.

As the miles and minutes passed, the crew on the customized cataraft was feeling strong and pulling hard on their oars, but their pace slipping.

“We just didn’t have enough water,” said John Mark Seelig, whose Colorado-based U.S. Rafting Team was joined by three veteran Colorado River guides on Friday and Saturday in a speed-record attempt to descend 277 miles through the Grand Canyon

As the river dipped to 10,000 cubic feet per second (cfs) and the crew outraced a pulse of water released from the Glen Canyon Dam upstream, the record slipped away…

The team of eight arrived at Phantom Ranch, at mile 88, at 11 a.m. on Friday, about 11 hours after they pushed into the Colorado River from Lees Ferry. That was only four minutes off their pace to reach the Pearce Ferry takeout around 10:20 a.m. Saturday. But that was also the peak of the surge released from Glen Canyon Dam. Holding close to a 5 mph rowing speed, the water slowed down with each mile. By midnight, the river had dropped from a daily high of close to 14,500 cfs to around 10,500 cfs

Speed records have a long history in the Grand Canyon, dating back to 14-day descents in the late 1800s on log rafts captained by adventurers who likely weren’t racing but simply rowing. In 1951 Grand Junction brothers Bob and Jim Rigg set out to purposely set the speed record. They pushed their wooden row boat into the river at Lees Ferry when the river was roaring at 43,100 cfs and finished in 52 hours and 41 minutes. That record stood until 1983, when Kenton Grua, Rudi Petschek and Steve Reynolds caught another flood-stage flow and rowed their wooden dory, the “Emerald Mile,” down the canyon in 36 hours, 38 minutes.

In January 2016, Orkin, an accountant in Aurora, paddled his carbon-fiber race kayak solo down the canyon, finishing in 34 hours and 2 minutes. That record was even more remarkable considering he flipped in Lava Falls and swam from his kayak, alone and at night.

The team this weekend had a clean run with zero mishaps.

Lava Falls: “This, I was told, is the biggest drop on the river in the GC. It’s 35 feet from top to bottom of the falls,” John Fowler. The photo was taken from the Toroweap overlook, 7 June 2010, via Wikimedia.

“We got our revenge on Lava. The boat was fantastic. Everything and everyone held up perfectly. We ran the lines we wanted,” Seelig said. “The water just wasn’t there for us.”

Orkin was paddling a narrow, sleek craft that sliced through water. The Emerald Mile was a wooden dory meant to cut through the river. The raft carrying eight — even with a pair of narrow pontoons beneath a lightweight frame — pushes water out of its way. It might not be possible for a raft to set a speed record in the Grand Canyon…

“OK, if someone was like ‘Hey, I have a permit on this date and it’s going to be this flow’ and we have a crew that is training — that’s a lot of variables — maybe who knows,” Seelig said. “But right now, I’m like ‘No way. Never again.’”

City of Durango plans temporary fix for dangerous rapids at Whitewater Park — The Durango Herald

From The Durango Herald (Jonathan Romeo):

The city of Durango plans to get back into the Animas River this winter to fix human-made rapids at the Whitewater Park that drew criticism for posing too great a risk to boaters during high water last summer.

Tweaks have been made to the Whitewater Park, which flows along Santa Rita Park, as early as the 1980s. But a full-scale $2.6 million project to enhance the park and build a series of rapids began in 2014 and was finished in 2018.

The most recent issue, which requires the city to get back in the river in the coming months, started three years ago and is considered separate from the Whitewater Park, which was led by the Parks and Recreation Department.

In summer 2016, the city’s Utilities Department spent $1 million to build several new features in the river, just above the Whitewater Park, for the sole purpose of diverting more water into the city’s water intake for municipal use on the east side of the river.

Since then, some members of the boating community have said the new features, which span the entire width of the river, function like low-head dams, one of the most dangerous hazards on a river because of the strong, recirculating water that can flip and trap boats, as well as people.

And if people fall out at the new drops, they have a long, cold swim through the actual Whitewater Park, which includes several major rapids and water temperatures in the low- to mid-40s…

This past summer, [Shane] Sigle said the only way to permanently fix the rapids would be to use grout to cement boulders in the river to ensure a safely designed flow. The U.S. Army Corps of Engineers (which issues permits for work in any waterways) and Colorado Parks and Wildlife, however, oppose using grout on river bottoms because it can adversely affect aquatic life.

City officials have said it’s unrealistic, and costly, to get back into the river every year to move boulders and rocks. But without being able to use grout, options are limited.

As a result, while long-term solutions are sought, it appears smaller maintenance projects are the city’s only way to make the river safer.

Jarrod Biggs, assistant utilities director, said the plan is to get in the Animas River as early as February to start the project, which could cost around $140,000 to $160,000.

Without grouting, though, the river will eventually move the boulders and nullify the improvements the city plans to make this year.

Grand Junction: Las Colonias River Park update #ColoradoRiver #COriver

From The Grand Junction Daily Sentinel (Duffy Hayes):

Since the River Park at Las Colonias now under construction is intended as a true collective asset — it’s not a raging whitewater course on some far-flung stretch of river, where only ardent and expert paddlers could realize the benefits — it certainly fits the community bill.

“Having done these projects for years around the country, you always think, what makes them popular, what makes them successful, what are all the ingredients that go into these?” Lacy said. “And location is extremely important.”

Even though previous efforts targeted other Grand Valley locations — Lacy still has concept drawings for projects that never got off the ground in Palisade and Fruita — he knew Las Colonias, where the city’s activation of the former uranium-tainted riverfront is front and center, is the right spot.

“I kept going, no, this Las Colonias thing — right there — and it’s developing, and it’s near downtown,” [Gary] Lacy recalled. “In the big scheme, all things being equal … that’s the best location.”

“You need infrastructure, and you need parking and restrooms. You need, ideally, restaurants — everybody gets hungry and thirsty and (wants to) get a beer and all that stuff,” he said.

“So in the heart of communities is by far the best.”

As Lacy puts it, river parks need two things — water and gradient. In the case of Las Colonias, you’ve got the biggest river in the state in the Colorado, and surveyors found that there was just enough gradient “for a good project,” Lacy said.

“We’re not talking world-class whitewater, but to be honest, you look back at the most successful ones, they (don’t have) the big, pounding whitewater that’s intimidating. Rivers and projects are for everyone,” he said. “I mean everyone, from a ducky to kayakers to stand-up boarders, or just people reading a book or having lunch along the river.”

“Those are the successful (projects), not the ones just for the 2% that are surfing,” he summarized…

TURNING TOWARD THE RIVER

It turns out lots of Gary Lacy’s projects are personal.

The office of his Boulder-based company, Recreation Engineering and Planning, fronts the whitewater park on Boulder Creek that he built in the ’80s.

The company is in the middle of a multiyear project to improve the river park in Salida, where his dad raced some of the first fiberglass boats in the ’40s and ’50s.

The Clear Creek Whitewater Park in Golden goes right by Colorado School of Mines, where Lacy’s dad encouraged him to enroll to become an engineer. He discovered his passion for civic and hydraulic engineering there, and built a unique-for-the-time business that initially focused on bike path construction a short time after.

A quick glance of the REP project list also includes Colorado river parks in Montrose, Buena Vista, Lyons, Steamboat Springs, Vail, Pueblo, Longmont, Florence, Breckenridge, Gunnison and Durango…

Many of the company’s projects in other parts of the country — like in Texas, Kansas, Wisconsin, Ohio and Oregon, among other states — involve taking dangerous dams out to create amenities where they were once liabilities. It’s a theme that also includes the rehabilitation involved at the previously tainted Las Colonias.

“All these communities are now turning toward the river, instead of turning their backs to the river,” Lacy observed.

Public asks Pitkin County for Basalt whitewater park to be safer

From Aspen Journalism (Heather Sackett):

Pitkin County needs to make Basalt’s whitewater park safer. That was the refrain from most of those who spoke at Wednesday night’s public meeting.

“We are not asking for a big change to the kayak park,” said Glenwood Springs resident Elizabeth Bailey. “What we are asking for is a way to get through these monster features.”

Bailey was among those boaters whose rafts were flipped by the lower wave during some of the Roaring Fork River’s highest flows of the season. Bailey, an experienced rafter, said that because the river pushes boats to the right-hand side of the lower wave feature, there needs to be a boat chute to the right, between the hydraulic that forms at high flows and the river bank.

Currently, the only way around the wave is a narrow, hard-to-spot “sneak” on the left side.

The injuries Bailey sustained June 16 sent her to the hospital.

“For that to happen in a manmade park, there needs to be some responsibility,” she said.

Pitkin County Healthy Rivers and Streams hosted Wednesday’s meeting at the Basalt Town Hall to gather public comment about the whitewater park’s two consecutive wave features, which some say became dangerous during this year’s high runoff. The lower of the two waves seemed to present the bigger challenge, even for experienced boaters.

The two structures, built with concrete during the winter of 2016-17, were re-engineered the following winter after complaints that the artificial waves were dangerous. But the low flows of the spring and summer of 2018 did not provide a fair test to see whether the problems had been fixed.

The features are supposed to create fun, recreational play waves at flows between 240 and 1,350 cfs. The river was flowing at about 2,500 cfs the day Bailey was thrown from her boat.

County committed

Healthy Rivers Chair Andre Wille said the county’s ultimate goal is to make the best whitewater park they can.

“We are pretty committed to getting it right,” he said.

Quinn Donnelly of Carbondale-based River Restoration, the firm that designed the park, led the public meeting and presented a few options for making the lower wave safer. Crews could lower the “wings” on both features, creating a path around the wave on either side, or a channel could be created around the left side of the wave.

Another idea was to create a “catcher’s mitt” eddy just below the second wave so that boaters who get tossed from their crafts can more easily swim to shore.

But some said creating a way for boaters to get around the waves didn’t go far enough — the waves themselves need to be made safer.

“Here you have two terrifying holes,” Kirk Baker said. Baker is the founder of the Aspen Kayak School and is an expert kayaker. “You should not have to go around. You should be able to go through. … You have to fix the hazard you created.”

Royal Laybourn agreed. Laybourn was also the victim of a flipped boat — he said the wave put him in the hospital.

“You can’t create a hazard and it doesn’t matter what water level it is,” he said. “You’re under a mandate to correct that. … Let’s just make it so any dummy can roll down through there.”

Safety first

Pitkin County chose the site for the whitewater park, which is just upstream from downtown Basalt, in part because it is just above the Roaring Fork’s confluence with the Fryingpan River. That made it a good place to establish a recreational in-channel diversion water right.

But that part of the river is also steep, Donnelly said, meaning hydraulics will not wash out, but, rather, become bigger as flows increase.

Any new modifications to the wave features that the county and River Restoration decide on will probably come this winter.

“We want it to be as safe as possible,” Donnelly said. “It is a river and there are hazards, but this was put in by people and it’s held to a higher standard.”

From Colorado Springs Utilities:

Project Overview / Background

The Homestake Project is a trans-mountain raw water collection, storage, and delivery system co-owned and operated by the cities of Colorado Springs and Aurora, Colo.

The Homestake Arkansas River Diversion (ARD), between Granite and Buena Vista, Colo., was constructed in 1964 as the original intake for the Otero Pump Station. Water is now primarily withdrawn from Twin Lakes, however the ARD remains an alternate point of diversion. The ARD has deteriorated and requires repair. The ARD was not originally designed as a navigable facility.

Colorado Parks and Wildlife (CPW) manages the Arkansas Headwaters Recreation Area (AHRA) which includes the site of the ARD. CPW expressed interest in partnering with Springs Utilities on a rehabilitation project to include a boat chute for downstream navigation as this location is currently considered the only non-navigable reach of the Arkansas River between Leadville and Canon City, Colo.

The Upper Arkansas River is both one of the most heavily used rivers in the United States for whitewater recreation and is a Gold Medal Trout Fishery. The river is managed to support multiple objectives including water supply and delivery and outdoor recreation.

The cities of Aurora and Colorado Springs are constructing a rehabilitation project that will replace the intake and diversion, provide a boat chute for downstream navigation, and provide upstream fish passage for spawning of brown and rainbow trout. The project also included improving river safety for recreational users and providing whitewater boat portage. User safety was an extremely important design consideration.

A physical model was constructed to test and refine hydraulic elements to optimize performance, maximize user safety and meet design guidelines for recreational whitewater for all three components: boat chute, fish passage and the new intake structure.

The $9 million construction cost of the project is being jointly funded by the cities of Aurora and Colorado Springs. $1.2 million in grants is coming from Colorado Parks and Wildlife and the Colorado Water Conservation Board through grant funding to support the Colorado Water Plan (Water Supply and Demand Gap and Environmental and Recreation Grant Programs). The Pueblo Board of Waterworks is donating the easements necessary to construct and maintain the diversion.

Here’s a report from Jason Blevins writing for The Colorado Sun:

But just below the former riverside mining camp of Granite, where a dilapidated dam built in 1964 has long blemished the Arkansas River’s beauty, rebar jutted from concrete blocks, preventing raft passage and spawning trout battled the steep wall of blasted rocks to reach upstream pools.

“Not a lot of thought went into recreation or fish when this dam was built,” said Ronald Sanchez, an engineer with Colorado Springs Utilities.

A lot of thought is going into fish and recreation now, as water managers in Colorado Springs and Aurora join the Colorado Water Conservation Board, the Pueblo Board of Water Works, Colorado Parks and Wildlife and the Arkansas Headwaters Recreation Area in rebuilding the diversion that directs water to the Front Range.

The $9.1 million project will make the entire river from Leadville to Cañon City navigable for rafts for the first time in at least 55 years.

It’s part of the vast Colorado Springs- and Aurora-owned Homestake Project that brings Eagle River Basin water from the Holy Cross Wilderness to the Arkansas River Basin, through the Homestake, Turquoise and Twin Lakes reservoirs for delivery to the Front Range cities.

The cities started construction of the Arkansas River diversion in July 2018, creating three distinct channels below a rebuilt intake that serves as a backup water diversion to the Otero Pump station downstream of Twin Lakes Dam. Before the Twin Lakes Dam was built in the late 1970s, the diversion was the original intake that collected and directed water to the Otero Pump station for delivery to Aurora and Colorado Springs.

One channel is a fish ladder for spawning brown and rainbow trout. Another channel is a spillway to accommodate flood-level flows like the ones that swelled the Arkansas River this spring. And a third is a series of six drops allowing rafts safe passage.

The project marks a new era of collaboration between the diverse interests on the Arkansas River between Leadville and Cañon City, one of the most recreated stretches of river in the U.S.

“For me the coolest thing about it is that you have these large water utilities in Colorado going above and beyond to do the right thing for the next 50 years,” said Salida-based whitewater park engineer Mike Harvey.

Ten years ago, Harvey helped the Arkansas Headwaters Recreation Area craft a report urging Aurora and Colorado Springs to consider recreation and fish when it came time to rebuild the Granite Dam diversion…

The Arkansas River accounts for more than $74 million of the $177 million in economic impact created by commercial rafting in Colorado. The 102 miles of river in the Upper Arkansas River Valley also ranks among the 322 miles of Colorado waterways that qualify as Gold Medal Fisheries that can yield a dozen large trout per acre. It also supplies a large percentage of water to Colorado Springs and Aurora via the 66-inch pipeline that runs from the Otero Pump Station.

Rebecca Mitchell, the executive director of the Colorado Water Conservation Board, said the project exemplifies the collaboration of the Colorado Water Plan, which gathered perspectives from all types of water users in the state to create a policy roadmap for future water planning across the state.

Colorado Parks and Wildlife and the conservation board provided $1.2 million in funding through Colorado Water Plan grant programs.
