Springtime Rain Crucial for Getting Wintertime Snowmelt to the Colorado River, Study Finds – Inside Climate News
The Never Summer Mountains tower almost 13,000 feet above sea level on the west side of Rocky Mountain National Park, the regal headwaters of the Colorado River. Snowmelt and rainfall trickle southwest from the peaks through jumbles of scree and colorful deposits of silicic rock, formed some 27 to 29 million years ago, then plunge into Gore Canyon. There, the river gallops downstream, absorbing other tributaries from Arizona, New Mexico, Utah and Wyoming on its way to California. More than 40 million people from seven states and Mexico depend on water from the Colorado River Basin to drink, irrigate crops, generate electricity and recreate, a demand that is greater than the river system can bear.
Historically, variations in snowpack would correlate with the amount of available water in the river come summertime. But since 2000, less and less snowmelt has been making its way into the Colorado River, and water levels in the river have not tracked as closely with variations in precipitation. A new study from the University of Washington, published today in the journal Geophysical Research Letters, offers a clue as to why this may be: increased evaporation and decreased springtime rainfall is leading parched plants and trees to suck up much of the snow melt before it ever reaches the river.
“These headwater areas provide around 70 to 80 percent of the Colorado River’s water,” said Daniel Hogan, a PhD student at the University of Washington who worked on the study. “Snowy peaks and all those high mountain rivers are really the linchpin of the system. So if less water is coming from there, then you can expect less water in the entire river.”

Hogan and a team of scientists used precipitation and streamflow data from 26 upper Colorado River basins—a large sample of the eventual river’s supply, accounting for about a quarter of the Colorado River’s streamflow—to study why there was a growing disparity between snowpack and water levels.
They found that the upper Colorado River basin had experienced a 9 percent decrease in annual spring rainfall compared with precipitation levels prior to 2000. Over half of the 26 basins they surveyed had “significant annual precipitation decreases,” they wrote. Spring had the most severe dropoff in rain, with a 14 percent decline compared to pre-2000 data. “Lower and middle elevation headwater basins were particularly affected,” with 12 of 17 showing “significant decreases,” they wrote.
This drop-off in spring precipitation appears to be especially detrimental to water levels in the summer. Though the researchers did find evidence of decreased rainfall in other seasons, spring rains accounted for 56 percent of the water-level variance.
“Spring precipitation decreases alone fall short of explaining observed streamflow deficits,” the team concluded, but when combined with other forms of water loss, like evaporation and nearby vegetation soaking up the moisture, that explained 67 percent of the variance.
Among the tens of millions of people the Colorado River is overpromised to are farmers irrigating about 5 million acres of agricultural land. But theirs aren’t the only plants impacting Colorado River levels. In their study, the research team worked under the assumption that trees and vegetation in forests ringing the Rockies need springtime precipitation to grow; in its absence, snowmelt becomes the plants’ primary source of water—and they have first dibs.
“It’s a very sound study,” said Tanya Petach, a climate science fellow with the Aspen Global Institute, which helps connect academics with outside organizations that can make use of their work. Petach, who was not involved in the University of Washington study, is a hydrologist who got her Ph.D. in environmental engineering from the University of Colorado. “It helps fill out part of the missing puzzle piece” as to why high levels of winter snowpack haven’t translated to large stream flow numbers in some recent years, she said.
The group’s findings read “like two knockout punches,” said Hogan. “You have less precipitation, so that leads to less streamflow, just inherently. And then, you also have a consequence of the trees and plants that still need their water,” which leads to “uncertainty in how much water we think we have.” He hopes this study helps water modelers understand the importance of using spring precipitation in addition to winter snowpack to predict how much water will be available in the river.
This study “puts a lot of momentum” behind improving spring forecasts for Colorado River stream flows, Petach said.
Hogan could not say for sure whether climate change has played a role in the decreasing springtime precipitation levels across the upper Colorado River basin as no part of their study was designed to investigate that possible connection. But other studies have already suggested climate change is driving droughts in the Colorado River’s upper basin.
Decreasing water levels across the Colorado River “could very well be linked to climate change directly,” Hogan said. “And if that is the case, then we can expect these declines to continue.”

New affordable housing communities in Colorado aim to serve families with the greatest need
LONGMONT, Colo. — For Skye Beck and her husband, the decision to uproot their family of five from Nebraska and relocate to Colorado for a new job wasn’t easy — especially when it came to the cost of living.
“It was looking like it maybe was not going to be an affordable option for us to come out here,” she said. “We did find one eventually, but it was still just the two-bedroom apartment, and that was just a little tight for us for the year.”
After a year of cramped living, the Beck family moved into a much more spacious apartment at Ascent at Hover Crossing in Longmont. The newest affordable housing development in Boulder County, which officially opened its doors on Tuesday, includes four-bedroom units — a rarity in affordable housing.
“I think they only have six of those [units],” said Beck. “To have that much space for the five of us is a blessing.”
Katie Pung, housing development project manager for the City of Longmont, said the larger units were a deliberate priority.
“Having those larger units for families really came together in a way that we feel like is going to be meaningful for Longmont families,” Pung said.
The mixed-income apartments are available for a variety of incomes, with units ranging from 30% to 80% of the Area Median Income (AMI) — about $31,650 to $84,400 for a one-person household.
The development also includes an early childhood education (ECE) center on site, giving families an affordable childcare option.
OUR Center, a longtime local nonprofit specializing in subsidized early education for low-income families, will operate the center. The facility is set to open later this year, with availability for both residents and the broader Longmont community.
It reflects a growing statewide push to incorporate childcare into housing projects through state funding and technical assistance for developers.

A similar effort is underway in Denver’s Berkeley neighborhood, where the Colorado Coalition for the Homeless is partnering with the Denver Housing Authority to develop Charity’s House, a family housing development with 135 new units — also with an on-site child care center.
At least 40% of the units will be reserved for families earning 30% of the Area Median Income (AMI) — currently $37,850 for a family of three and $42,050 for a family of four in Denver. All units will be income-restricted to those at or below 60% AMI.
Cathy Alderman, chief communications and public policy officer for the Colorado Coalition for the Homeless, said land partnerships help reduce both cost and construction time.
“If we can enter into a partnership with another organization that owns land, and we can build on that, that cuts our cost and time down considerably,” Alderman said.
The DHA Delivers for Denver (D3) bond program, a partnership between DHA and the City of Denver, has funded 11 property acquisitions since its inception in 2019, according to Denver Housing Authority Chief Real Estate Officer Erin Clark.
“It is public partnerships like that and public-private partnerships that, even us, working with a nonprofit here, that are what deliver more housing across the community,” said Clark. “It’s just people thinking outside of the box and leveraging resources and saying, ‘What do you do best, and what do we do best, and how can we work together to make all this happen?’”
Construction is slated to begin in late 2027.
Denver7 has heard from multiple experts through the years about the lack of affordable housing options for families and seniors.
Years-long waitlists and housing lottery odds often make it tougher. More than 15,000 children and youth are currently experiencing homelessness in Denver.
Colorado has been making significant housing investments since the COVID-19 pandemic, leading to more affordable housing developments across the state. But Alderman said there is still more work to be done.
“My biggest concern is that not all of that housing is being targeted for those households in the greatest need,” Alderman said.
Longtime Longmont resident Karen Howerton remembers a time when rents hovered in the $600 range.
“When I came back to Longmont six years ago, I was surprised at how much inflation had happened here and how big the town had grown,” she said.
The last affordable housing development she lived in didn’t quite fit all her needs.
Now, she joins the Becks as one of the first tenants at Ascent at Hover Crossing.
“What I wanted to come over here for was a washer and dryer — I didn’t have that at my other place — and the little balcony, you know,” she said. “I’ve met a few of the neighbors already, and I can’t say enough about it. It’s just a great place to be, for sure.”
Howerton and Beck say the little comforts go a long way toward making a place feel like home.
“I mean, everyone deserves to have a space and be able to afford it without worrying about all the other parts of life,” Beck said. “I feel like here we’re able to finally rest a bit and able to enjoy life, but it shouldn’t be limited to just a waitlist.”

Colorado weather: Up to 14 inches of snow forecast for mountains
Snow started Monday night in Colorado’s mountains and will continue throughout the week, likely making its way into the Denver area on Friday, according to the National Weather Service.
Colorado’s mountain roads, including Interstate 70 at the Eisenhower-Johnson Tunnel and Berthoud Pass, were already snow-covered Tuesday morning, according to the weather service.
“With more snow to come throughout the day, a Winter Weather Advisory was issued for the Front Range Mountains,” forecasters said.
That advisory will be in effect until 8 p.m. Tuesday for parts of Jackson, Larimer, Boulder, Grand, Gilpin, Clear Creek, Summit and Park counties, including Rocky Mountain National Park. Additional snow accumulations between 6 and 14 inches are possible on Tuesday, forecasters said in the alert.
As of Tuesday, the weather service’s snow forecasts included:
- 2 inches on I-70’s Vail Pass, with up to 3 inches possible
- 3 inches in Winter Park, with up to 4 inches possible
- 4 inches in Eldora and on U.S. 6’s Loveland Pass, with up to 5 inches possible
- 4 inches on U.S. 40’s Berthoud Pass near Winter Park, with up to 7 inches possible
- 5 inches at Bear Lake in Rocky Mountain National Park, with up to 7 inches possible
- 6 inches on U.S. 34’s Milner Pass in RMNP, with up to 8 inches possible
- 7 inches on Colorado 14’s Cameron Pass near Fort Collins, with up to 8 inches possible
- 9 inches on Mount Zirkel, the highest summit of Colorado’s Park Range of the Rocky Mountains, with up to 11 inches possible
“Travel could be very difficult,” weather service forecasters stated in the winter weather advisory. “The hazardous conditions will impact the Tuesday morning and evening commutes.”
Snow is expected to pause in the mountains Wednesday and resume Thursday before wrapping up early Saturday morning, according to hourly forecasts from the weather service.
In the Denver area, snow is most likely between 5 a.m. and 4 p.m. on Friday, the hourly forecasts show. Rain is also forecast for the metro area during that time, so it’s unknown how much snow will stick.

Weiss keeps focus on job as Colorado AHL assistant, not historic promotion | NHL.com
In NHL.com’s Q&A feature called “Sitting Down with …” we talk to key figures in the game, gaining insight into their lives on and off the ice. This week, we feature Kim Weiss, assistant coach of the Colorado Eagles, the Colorado Avalanche’s American Hockey League affiliate. Weiss was named assistant for the Eagles on Jan. 16, joining Seattle Kraken assistant Jessica Campbell as the only women in the NHL or AHL to be a full-time assistant coach.
Kim Weiss doesn’t think about the history she’s made that often.
The 36-year-old is too busy with her duties that come with being the Colorado Eagles’ assistant coach, including breaking down 5-on-5 video — she was the team’s video coach prior to her promotion — presenting it to the team, pushing pucks and running practice drills.
“When the title change happened and the promotion happened, I left the office of the general manager (Kevin McDonald), and I got back to work,” Weiss told NHL.com. “In the moment you’re not really thinking about that kind of stuff, but obviously it’s an honor.
“I’m especially grateful just because of my background. I didn’t play on a national team, I didn’t grow up in Minnesota or any kind of a hockey hotbed. So to get at this level and to have this legacy, for lack of a better word, from the place I’m from, a kid from Maryland that played Division III (hockey at Trinity College), it makes me even more proud to show people that you can get somewhere no matter where you start from. Then you add in being a female and all of that, I’m really proud of my journey and I’m proud of all the people who helped me along the way to get here.”
It’s been quite a ride for Weiss with the Eagles, who are second in the AHL Pacific Division. Last week, Weiss talked to NHL.com about her new duties, working with the Avalanche and more women in hockey.
So what was it like the day McDonald called you into the office to give you the news of your promotion?
“Honestly, it’s an affirmation of the work you put in. That’s what the GM said to me. Last season I had a different head coach (Aaron Schneekloth) and we had a different assistant (Dan Hinote) that both moved onto the NHL, and they both spoke highly of me to our GM in the summer and to our new head coach (Mark Letestu). Getting to know Mark this year and working for him, everything that he had heard of me got confirmed through the first few months of the year.
“I don’t exactly know how the process went about to change the title, but I think he went to Kevin, and I know Kevin said this to me, this line of, ‘You’re doing all the work that the assistant does, so why aren’t we calling you one?’ I’m already on the ice with the team and I run skill skates and scratch skates and present (video). I’m doing everything the assistant coach does; I just had a different title. So I really appreciate them just giving me the opportunity to kind of advance my career and keep doing what I love to do, which is coach hockey.”
Letestu also had you run one of the practices earlier in the season. How did that come about?
“Every assistant got (that chance). The big thing coming in was, he had been an assistant coach before and he wanted to make sure we all had a voice and a say, and we weren’t just coming onto the ice for practice like, ‘Oh, here we go. Push some pucks. Put my track suit on for 20 minutes, push some pucks and jump off.’ He wanted to make sure we had the platform in front of the players.
“It started with our longest-tenured assistant coach, Tim Branham. It was nothing new or scary for any of us, but just a different dynamic. Not every staff allows their assistants to take full responsibility of a full practice. Then Derek (Army) took it and then the next week I took one.”
