Springtime Rain Crucial for Getting Wintertime Snowmelt to the Colorado River, Study Finds – Inside Climate News

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.”

Colorado breweries warn new tax hike bills could lead to more small business closures, job losses

Colorado breweries warn new tax hike bills could lead to more small business closures, job losses


A bartender pours a beer at a bar in Summit County on Thursday, Feb. 29, 2024. A new bill intended to provide funds for alcohol-related addiction prevention, treatment and recovery programs could cost small breweries and wineries up to 160% in taxes and fees.

Colorado brewers are raising red flags over new bills that could increase taxes and fees on small alcohol businesses, many of which are already struggling to keep their doors open.

House Bill 1271, known as the Alcohol Impact & Recovery Enterprises bill, creates three government-run enterprises designed to fund programs for alcohol-related addiction prevention, treatment and recovery programs — all funded through fees imposed on alcoholic beverages. The bill is sponsored by four Democratic lawmakers.

Colorado per capita alcohol consumption is higher than the national average. The state also has one of the higher alcohol-related death rates in the country, with around 24 deaths per 100,000 residents as of 2023, according to data from Trust for America’s Health. 



Data from the Colorado Health Institute shows not everyone who could benefit from treatment for alcohol use disorders currently receives it, largely due to factors like cost, accessibility and stigma.

Were the bill to pass, manufacturers and wholesale distributors would have to pay five cents in fees per gallon of beer, cider and apple wine, seven cents per liter of wine and 35 cents per liter of spirits to be used toward alcohol-related treatment and recovery programs. As state lawmakers plan cuts to balance a $850 million budget deficit, advocates for these programs argue the funding from the bill could help offset any potential losses.



For local breweries and wineries in the mountains, however, this would be a significant financial blow to an already struggling industry.

“This is not the time for us to be implementing new taxes on an industry that is hurting right now,” said Carlin Walsh, owner of Elevation Beer Company and chair of the Colorado Brewers Guild. “As a brewer, I feel like the state is looking a gift horse in the mouth.”

Beer, wine, cider and spirits generate around $22 billion in economic activity for Colorado, according to the Colorado Beverage Coalition. The state is home to nearly 420 breweries, 145 wineries, nearly 20 cideries and 100 distilleries. 

Faced with rising costs and waning appetites, however, over 100 Colorado breweries have shuttered their doors since 2024, marking the first time since 2005 that more breweries closed than opened. Meanwhile, national surveys confirmed alcohol consumption in the U.S. is at a 90-year low.

Walsh said breweries already pay eight cents per gallon in taxes, which for a company like Elevation translates to roughly $30,000 in taxes annually. Fees from the new bill would add another $12,000 to its yearly expenses.

“The alcohol industry at large is one of the most regulated industries in the United States, period. We already pay a very heavy tax,” Walsh said, adding that breweries provide tens of millions of dollars to Colorado’s general fund. “Our position is that there’s already money available. Those dollars go to the general fund, and it’s really up to the state to manage what we already provide and to decide what is their priority. We don’t feel like it should be on our shoulders to increase the amount that we pay to the state just because the state wants to endeavour on new programs.”

The Colorado Beverage Coalition said the imposed fees would be a 60% cost increase on alcohol businesses. Paired with an estimated 100% increase in taxes from a referred ballot measure proposed last week — House Bill 1301 — the impacts would be disastrous for the industry, Walsh said.

House Bill 1301 would refer a measure to the November ballot that would increase excise taxes on alcohol and increase sales and excise taxes on marijuana in order to fund a mental health hospital in Aurora.

“Our brewery and so many other breweries, we just don’t have capacity for that. We’re already a low margin business to begin with,” Walsh said. “If this happens, this is going to drive further consolidation amongst our members. It’s going to drive further closures.”

Larger alcohol companies may be in a better position to absorb some of the costs from increased fees, said Shawnee Adelson, executive director for the Colorado Brewers Guild. Small businesses in rural resort markets, on the other hand, are not in that position.

“At a certain point when costs just keep going up and up and up, there’s no more place to cut,” Adelson said.

Colorado jobs, tourism could see ripple effects

The Colorado Beverage Coalition estimates House Bill 1271 could impact several of the 131,000 brewery, winery and distillery jobs in the state.

The Colorado Beverage Coalition estimates House Bill 1271 would jeopardize 131,000 brewery, winery and distillery jobs in the state, in addition to “greatly increasing cost on consumers.” Walsh said an average brewery would “no doubt” have to cut jobs if either, or both, bills were to pass.

“Depending on the size of a brewery, it could be the cost of a full-time staff or multiple full-time staff to cover the cost of these (fees), so there is a real concern about job losses due to increased costs,” Adelson added.

The Colorado Distillers Guild also argues the bill would be a blow to the tourism industry, as visitors could be deterred by increased consumer costs and a dwindling beer culture.

“A lot of (breweries) will either have to absorb that cost or pass it on to the consumer. And right now, in the current state of the economy, we understand that a lot of consumers are price conscious right now, which is also contributing to lower consumption,” Adelson said. “Passing on that price is going to be really hard for consumers to swallow as well.”

The bill is not entirely new, as similar legislation by the same name was proposed in 2024. The original bill, which died in committee, received significant pushback from Gov. Jared Polis due to concerns that it would end up raising prices for consumers. Polis also requested that sponsors exempt beer companies from the fees.

Aside from a stakeholder meeting ahead of the bill’s introduction, Adelson said the Colorado Brewers Guild had not been contacted by lawmakers about the plan for an excise fee increase.

“We’ve had two years to sit down and have discussions with lawmakers about this. Nobody has reached out. Nobody has sat down with us to say, ‘Hey, this is our goal. We wanna get this done. How can you guys meet us halfway?’” Walsh said.

Being an enterprise fee rather than a tax, House Bill 1271 would not go to voters for approval. Instead, the change would be implemented through legislation only and automatically go live in July 2027. Because the bill would create three separate enterprise fees for beer, wine and spirits — each capped at $20 million annually per state law — the state could collect up to $60 million from all three.

The bill would also create a new 11-member board appointed by the governor to oversee the three enterprises, which would be made up of alcohol industry representatives, behavioral health professionals, public health experts and individuals in recovery.

On top of feeling that a financial change of that magnitude should be left up to voters, Walsh said he’s heard from businesses that are concerned about the potential for the board to increase fees in the future.

“There are very few guard rails around how this enterprise can operate, including the ability for them to raise the tax price that we’re currently paying. There’s very few restrictions within this bill that control how much they can increase that tax,” Walsh said. “In two years they could come back and say, ‘Oh we’re going to increase it another five cents or 10 cents.’”

For Adelson, the fees would impact more than just manufacturing facilities and business  operations.

“They’re community gathering spaces and they’re third places,” Adelson said. “They give back a lot and so I think I just want to make sure that the consumer realizes that we’re not just talking about production facilities, but your local neighborhood brewery that’s down the street and that your neighbours own or your friends work at.”

New affordable housing communities in Colorado aim to serve families with the greatest need

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.”
