BASALT – Flows in the lower Fryingpan River below Ruedi Reservoir were increased on Friday afternoon to about 300 cubic feet per second, much to the dismay of professional and private anglers who prefer a flow of no more than 250 cfs.
“We get cancellations at 250 and up,” said Warwick Mowbray, owner of Frying Pan Anglers in Basalt, during a meeting Thursday night in Basalt’s town hall on flows in the Fryingpan. “People say, ‘We can’t wade.’”
Releases from Ruedi were increased Friday in order to send more water to the “15-mile reach” of the Colorado River between Palisade and Grand Junction for the benefit of endangered fish species struggling to survive in the river below several big irrigation diversions.
But the water released from Ruedi and sent down the Fryingpan, Roaring Fork, and Colorado rivers to the 15-mile reach at the direction of the U.S. Fish and Wildlife Service erodes the quality of the trout-fishing experience on the lower Fryingpan, according to Will Sands, manager of Taylor Creek Fly Shops in Basalt and Aspen.
“Over 250 cfs changes the dynamic of the environment of the river for hatches and the abilities of the visiting angler,” Sands said. “It hits 300 and we start getting cancellations.”
Rick Lofaro, director of the Roaring Fork Conservancy, seconded the concerns of the professional anglers.
“When you have additional water coming down, it challenges wading and changes the character of the river,” he said, likening higher flows in the Fryingpan to paying for a backcountry powder tour only to find no fresh snow. “I think there is a big difference between 250 and 300 from an accessibility and wade-ability level.”
The conservancy commissioned a study in 2014 that showed fly-fishing contributes $3.8 million to Basalt’s economy.
Thursday’s meeting in Basalt was called by officials from the Bureau of Reclamation and the Fish and Wildlife Service, and about a dozen citizens showed up to discuss likely releases from Ruedi for the balance of the summer.
Tim Miller, a hydrologist with the Bureau of Reclamation who manages Ruedi Reservoir, said releases below the reservoir would likely be around 300 cfs into September, but could be as high as 350 cfs if there is a call for more water from irrigators in the Grand Junction area.
Since July 18, flows in the lower Fryingpan have been running steadily at around 245 cfs, a sweet spot for anglers.
Jana Mohrman, a hydrologist with the Fish and Wildlife Service, manages a pool of water in Ruedi that can be released to keep enough water in the 15-mile reach.
She works toward meeting seasonal flow levels — now 1,240 cfs — in the Colorado River near Palisade by directing “fish water” to that point on the river from a variety of upstream reservoirs, including Ruedi, Wolford and Green Mountain.
This week, flows in the Colorado River near Palisade had dropped to the point where several fish passages designed to allow native endangered fish to swim upstream toward Rifle were not functioning due to low water levels.
“I’m using Ruedi to get my fish passages open,” Mohrman said.
As such, she directed the Bureau of Reclamation to release another 50 cfs from Ruedi starting Friday. That was on top of the 140 cfs of “fish water” that was already being released, which was in addition to about 110 cfs of routine releases from the reservoir.
Mohrman’s pool of “fish water” in Ruedi equals about 15,000 acre-feet of water. But she can also use, for the second year in a row, about 9,000 acre-feet of water owned by the Ute Water Conservancy District in Grand Junction and leased to the Colorado Water Conservation Board for use in the fish-recovery program.
On Wednesday, during a weekly conference call of regional reservoir managers and irrigators, Mohrman was pressured by irrigators in the Grand Valley to release more water from Ruedi along with water they were releasing for the fish from Green Mountain Reservoir, which serves as a back-up water supply for the Grand Valley.
Last year, 24,412 acre-feet of water was released from Ruedi to the benefit of the fish-recovery program and a similar amount is likely to be released this year. In all, Ruedi can store 102,373 acre-feet of water.
Of that, about 41,000 acre-feet is owned by various entities, and can also be released upon demand in a dry year. Should that occur, flows in the Fryingpan could rise still higher, and not just because of the fish-recovery program.
“These demands on the reservoir are only going to grow,” said Miller of the Bureau of Reclamation. “This isn’t going away.”
Dan Turley, a homeowner in the Fryingpan River Valley and an avid angler, asked Mohrman if the endangered fish program was a higher priority than the recreational economy of Basalt.
“This is not a trivial inconvenience,” Turley said of flows in the Fryingpan going up to 300 cfs. “It makes the river not viable to fish for a great majority of people.”
And Turley said it’s not just about Basalt’s economy.
“A lot of people from Aspen come down here and fish,” he said. “They are staying at The Little Nell. This is a big deal.”
“It’s always been considered,” Mohrman said, referring to the local fly-fishing economy and a targeted flow of 250 cfs in the Fryingpan. “And we have always said we would try to maintain 250. But we also have to recover these fish, and we’ve built all these structures to try and get them up to Rifle to get back into their natural habitat. And that is a higher priority than the 250 target.”
The goal of what’s called the Upper Colorado River Endangered Fish Program is to maintain populations of four species of large fish native to the Colorado River, the Colorado pikeminnow, razorback sucker, bonytail, and humpback chub.
If the program fails to maintain viable populations of native fish, diverters in the Colorado River basin could be faced with extensive environmental reviews of their diversion’s effects on the endangered fish — something regional water managers want to avoid.
As long as the fish populations are stable or growing, the recovery program provides blanket environmental protection. Trouble is, Mohrman said the fish are not doing all that great as they are being preyed upon by non-native fish in addition to struggling with low river levels.
Rachel Richards, a Pitkin County commissioner who has focused on water issues during her tenure, attended Thursday’s night meeting.
She raised the idea of a pipeline or flume that would allow water to be released from Ruedi without flowing down the river itself.
“We’ve always talked a little bit about should there be a separate flume or waterway for the Ruedi releases so they are not destroying the Fryingpan,” Richards said.
She also said that Pitkin County and Basalt had voiced concerns in the past about releasing “fish water” from Ruedi and making Basalt a “sacrificial lamb for water needs elsewhere in the state.”
At the conclusion of Thursday’s meeting, Mohrman said she would work with irrigators and reservoir managers to see if more water can’t be released from reservoirs other than Ruedi.
“I’ll try and cut it back as the Green Mountain Reservoir ups its releases and our fish passages stay open,” she said. “I understand your very serious concerns.”
