From The Glenwood Springs Post Independent (Jason Auslander):

A spate of warm weather predicted for the next several days is likely to prompt high flows for this time of year in the Roaring Fork River and other area waterways, forecasters and river watchers said this week.

That’s because the snowpack in the high country remains huge for this time of year, said Valerie MacDonald, Pitkin County’s emergency manager.

“It’s mind-blowing,” she said Thursday. “It still looks like winter in a lot of places.”

On Thursday, the Roaring Fork River at Stillwater Bridge east of Aspen was running at about 400 cubic feet per second, said April Long, Clean River Program manager for the city of Aspen. The river is expected to rise to between 600 and 650 cfs in the next three days or so and remain at about that level for the next week, according to predictions by the Colorado Basin River Forecast Center.

And while that is roughly the river’s historic level at about this time of year, generally the rivers are decreasing in flow now rather than rising, which is what’s happening, according to Long and historical data on the CBRFC website…

The river peaked above Aspen on June 21 about 900 cfs, [Greg Smith] said.

From KOAA.com (Caiti Blase):

High and powerful waters in the Arkansas River have now caused a partial breach in a Canon City levee and a section of the riverwalk was forced to close…

The impacted section is about 100 feet and city leaders say that while the ground underneath has been stabilized it’s only a band-aid fix and that part of the trail has collapsed…

Kyle Horne, executive director of the Canon City Area Recreation and Park District, said, “We started seeing collapsing trail and other things, and we knew that we were going to have problems. We also saw an increase in groundwater in the parking lot in the low area adjacent to the levee.”

With the river flowing at a powerful 5,000 cubic feet per second for the last few weeks, Horne said, “It then gets into areas it normally doesn’t make it into and it starts chewing away at banks.”

Eventually, causing a slight breach in the levee and part of the trail to collapse.

From The Aspen Times (Scott Condon):

The U.S. Bureau of Reclamation reduced releases from Ruedi Reservoir earlier this week but hydrologist Tim Miller acknowledged it’s a crapshoot right now whether adjustments will be required as the ample high-elevation snowpack melts out.

Ruedi was releasing in excess of 600 cubic feet per second as part of the Coordinated Reservoirs Operations program for the benefit of four endangered fish. The flows boosted the level of the Colorado River in habitat for humpback chub, razorback sucker, bonytail club and the Colorado pikeminnow upstream of Grand Junction.

Miller said about 5,000 acre-feet of water from Ruedi was released for the endangered fish program. Once the program was over, he dialed the releases back to about 350 cfs to try to ensure the reservoir fills.

The inflow to Ruedi from the upper Fryingpan River dipped to 600 cfs on Tuesday and was at 591 cfs on Thursday. That was about half of the June 22 peak of 1,300 cfs.

The federal River Forecast Center envisioned inflow rising again to 800 cfs and then gradually receding…

The big unknown is how much snowpack remains at high elevations and how it will melt out. Miller said snow telemetry sites in the Upper Fryingpan Valley have melted out. However, those automated sites are at lower elevations. There is still significant snow in higher basins. The warm weather this week is eating into the snowpack. If the inflow to the reservoir spikes again, releases also will increase.

From The Denver Post (Sam Tabachnik):

The Mineral County Sheriff’s Office reported the [Rio Grande River] will remain closed [as of June 28, 2019] to all boating because of turbulent water and the ongoing search [for a missing boater]…

Thursday was the first day the river was open to boaters, Rice said. The waterway had previously been closed off due to unsafe conditions. Still, officials advised only experienced boaters should take to the water Thursday, Rice said, and people were urged to use extra caution.

Colorado program that enhances streams gets a second chance at expansion this summer — @WaterEdCO

From Water Education Colorado (Shay Castle):

With Colorado’s snowpack at historically high levels and several towns turning their attention from avalanches to potential flooding, most people in the state probably aren’t thinking about preparing for drought years. But state lawmakers, farmers and environmentalists are.

Together, they are working over the summer on potential expansions to a program that allocates water specifically to benefit streams and aquatic habitat in dry times.

The measure failed at the State Capitol this year, but HB19-1218, Loaned Water for Instream Flows to Improve Environment, will be taken up again this summer by the legislature’s Interim Water Resources Review Committee.

The first effort was championed by conservationists like The Nature Conservancy and opposed by some farmers, who worry it could harm water rights reserved for agriculture.

“Our businesses are totally based on the value of those water rights,” said Carlyle Currier, vice president of the Colorado Farm Bureau and a rancher in Molina, Colo. “We’re very concerned that changes would allow that right to be injured.”

Colorado’s Instream Flow Program was established amid the environmental movement of the 1970s to integrate environmental water needs into the state’s intricate system of water rights. Colorado’s water laws work on a priority system: Those whose water rights were established earliest get first dibs in dry years. Before the instream flow law was created, there was no mechanism to establish a water right specifically to keep water in a stream to protect fish and the environment. Rather, water rights were all about diverting that water from the stream.

The Instream Flow (ISF) Program uses water rights within that same priority system to reserve water for environmental purposes, protecting the plants and animals that depend on streamflows.

To date, 9,600 miles of stream have been protected through ISF, according to Linda Bassi, chief of lake and stream protection with the Colorado Water Conservation Board — nearly a quarter of the state’s 40,000 miles of waterways. The CWCB doesn’t have a goal for how many miles of stream it would like to eventually protect, Bassi said, instead taking recommendations from state and federal agencies, local governments and environmental groups for specific stream segments in need of protection.

The CWCB is the only entity that can legally hold ISF water rights. It gets them through establishing new, junior water rights, or by acquiring existing water rights via donation, purchase, lease or other contract. HB19-1218 was concerned with the leasing of existing water rights for ISF purposes.

Under current law, water rights holders can lease their water to the ISF Program only three years out of any 10-year period, and are limited to one 10-year timeline. After that, to maintain ISF protection on a given stretch of stream, the CWCB has to find another water rights holder to lease from, or work out another agreement to preserve the water.

The state can and does employ different means to protect a stretch of water on non-lease years. But “leases are the simplest and easiest way to pull this off,” said Andy Schultheiss, executive director of the Colorado Water Trust, a nonprofit that works with the CWCB on the ISF Program.

Under the proposed legislation, the CWCB would be able to lease water rights for five years out of 10, and the 10-year periods could be renewed twice. Extending protection to 15 years out of 30 will help sustain the environment as drought cycles become more erratic due to climate change, said Aaron Citron, policy advisor at The Nature Conservancy.

“What we’re trying to do is provide a tool that can address critically low stream conditions under a more variable future scenario,” Citron said. Even if HB19-1218 had passed as-is, the expanded ISF Program would not “fully meet the need we think we will see under climate change.”

Both Schultheiss and Citron agree that the way ISF rights are being used today shows that there is more demand for instream flow protection than supply. Two of three available years have been used in a lease of water from Stagecoach Reservoir near Steamboat Springs to benefit the Yampa River, according to Citron, and the Colorado Water Trust is holding off on using the third for when conditions are most dire.

“Last summer, there were stretches when the only water in the Yampa [River] through Steamboat Springs had been leased [for instream flow],” Schultheiss said.

As far as the state’s farmers are concerned, expanding instream flows goes a step too far. The Colorado Farm Bureau opposed HB19-1218 for the primary reason of protecting existing water rights.

“It seems like it was a little bit of a backdoor to expand ISF rights without going through the vetting process,” said Currier. “That’s a little frightening to those of us who own water rights.”

To establish a new ISF water right on a particular stream, there is a three-year process that ends with a review by Colorado’s water court to determine, among other things, that the instream right won’t negatively impact other water rights holders. Extending lease periods that significantly without a return to water court could harm farmers, Currier said.

Under the proposed rules, Currier worries that two five-year leases could be stacked back-to-back, leaving water in streams for 10 consecutive years while fields go fallow.

The Farm Bureau is also concerned about a third proposal for the ISF Program. Currently, leased water rights can only be allocated for instream purposes in a quantity great enough to preserve the natural environment “to a reasonable degree.” The Nature Conservancy wants to go beyond preserving existing conditions to allow improvement of natural conditions as well.

“That language is a little troubling to us,” Currier said. “That is not a quantitative term. Who determines what’s an improvement? What exactly does that mean?”

The CWCB already has the authority to acquire water rights that improve the environment, Citron said, just not for ISF leases.

This and other ISF issues will be discussed at the next meeting of the legislative interim water committee as part of the 2019 Colorado Water Congress annual summer conference, being held Aug. 20-22 in Steamboat Springs. Both sides remain hopeful that a compromise could be reached, though Currier noted farmers are resistant to making changes that they feel haven’t been properly vetted for potential negative impacts.

“We’re not out to destroy the environment; we’re more dependent on it than the average citizen,” Currier said. “We really feel the existing water law is written fairly well and we don’t see a lot of need for changes to that.”

If the interim water committee is able to craft new language that satisfies agricultural and environmental interests, a new bill will be introduced during the next legislative session, which convenes Jan. 8, 2020.
