Considering the Denver region is growing by an average of 4,500 new residents per month, a large sector of the population likely doesn’t remember the catastrophic 2002 drought. The most severe water shortage since the Dust Bowl, snowpack and soil moisture were at all-time lows, and we remained in a dry period until 2006. Luckily, with water restrictions in place, we never actually ran out of water—we just got really close.
“We realized that we had an immediate need to correct a vulnerability in our system,” Denver Water CEO Jim Lochhead says. That’s when Denver Water started planning the Gross Reservoir Expansion Project, and after more than a decade of negotiations, the project (which was recently endorsed by Gov. John Hickenlooper) is underway.
But will it be enough? The short answer is yes—as long as Denverites work on strengthening their water conservation practices. Lochhead was pleased to note that when a storm comes through the Mile High City, there is a noticeable drop in outdoor water use, because well-informed residents are turning off their sprinkler systems. Denver residents have managed to reduce water consumption by more than 20 percent in the last 15 years, even with a 15 percent increase in population, according to Lochhead.
The decrease is not enough to mitigate the risk of drought, however. As Colorado’s largest water utility, the Denver Water system is made up of two collection systems—the Northern and the South Platte—and they are incredibly imbalanced. About 80 percent of the water comes from the south system, leaving the north very vulnerable to low rainfall or wildfires. During the notable dry years of 2002 and 2013, clients in the north end were lucky their taps continued to flow.
“We were literally only one drought away from a major problem in our system,” Lochhead says, noting that as recently as 2013, the system was virtually out of water in the north-end.
The Vasquez Canal Project is a multi-year multi-million dollar project that continues efforts by Denver Water to improve existing water diversion infrastructure. Work on the Vasquez Canal Project focuses on removing sections of the existing Vasquez Canal and replacing removed sections with a 114-inch diameter concrete reinforced pipe.
Work on the project has occurred in previous year with Denver Water replacing between 5,000 and 6,000 feet of the Vasquez Canal over the past two decades. Officials from Denver Water say they plan to replace about 2,000 feet of the Vasquez Canal in 2016, leaving roughly 15,000 feet to be replaced in the future.
Officials from Denver Water did not provide an overall projected cost on the project pointing out that, “funding allocation for this project is reassessed annually”. In previous year the project averaged around $750,000 per year in costs. Future projected cost estimates on the Vasquez Canal Project total between two to three million dollars annually.
Monies used for the project come directly from Denver Water which is funding operation, as it does all operational and capital projects, through water rate fees, bond sales, cash reserves, hydropower sales and system development charges for new services.
Work on the Vasquez Canal Project consists primarily of excavation and earth moving to facilitate the canal upgrade. “Crews will demolish the old concrete liner and covers, excavate the area and install the new 114-inch pipe, piece by piece,” stated Denver Water Communication Specialist Jimmy Luthye. Luthye explained Denver Water plans to, “work aggressively to complete this project in the next few years in an effort to replace aging infrastructure and improve the safety and strength of the entire water system.”
Ames Construction is the contractor of record for the project. For the past 20 years though, as previous sections of the Vasquez Canal have been replaced, employees of Denver Water performed the upgrade work. According to Denver Water this is the first year work on the project has been contracted out.
The Arapaho National Forest prepared an environmental assessment of the Vasquez Canal Project. All construction work on the project is being conducted entirely on National Forest System Lands. According to Denver Water that environmental assessment determined, “there would be no significant environmental impacts.” Officials from Denver Water went on to state, “They approved the project along with required best management practices, design criteria and monitoring designed to protect the area during construction.”
The Vasquez Canal is part of Denver Water’s historic water diversion network that brings mountain runoff to the Front Range and Denver Metro area. The original canal was completed in the late 1930s. According to Denver Water, information on the original construction of the canal is fairly limited but officials from the municipal water supplier stated, “we suspect that some of it (Vasquez Canal) was originally dug by hand because the canal had to be cut into the side of a steep mountain… making it difficult for machines to access.”
In the late 1950s Denver Water covered the originally open Vasquez Canal, effectively creating a tunnel. A drought during the early 1950s prompted the action, which was intended to mitigate evaporation as water traveled through the diversion system.
Water utilized by the Denver Water’s diversion system follows a zigzagging path of infrastructure as it descends from snowmelt in the high Rockies to homes along the Front Range.
Diversion structures in the Upper Williams Fork River send water through the Gumlick Tunnel, formerly known as the Jones Pass Tunnel, where the water passes under the Continental Divide. From there water travels through the Vasquez Tunnel, which brings the water back through to the other side of the Continental Divide, where it enters into Grand County and Vasquez Creek. The water is then diverted through the Moffat Tunnel back under the Continental Divide for a final time and into South Boulder Creek, feeding into Gross Reservoir, a major water storage reservoir for Denver Water.
FromThe Grand Junction Daily Sentinel (Dennis Webb):
A proposal to divert Colorado River water to Denver recently has won the endorsement of Gov. John Hickenlooper and the approval of the Colorado Department of Public Health and Environment.
But Denver Water’s Gross Reservoir expansion project may be just as notable for its general lack of opposition west of the Continental Divide. That’s thanks to a wide-ranging agreement, effective in 2013, in which Denver Water obtained concessions including a promise that numerous Western Slope parties to the agreement wouldn’t oppose the expansion project. In return, Denver Water made a number of commitments to the Western Slope.
Now Western Slope interests are working on a similar agreement with Northern Water and others on what’s called the Windy Gap Firming Project, which would store Colorado River water in a proposed Boulder County reservoir.
These approaches represent a far cry from how the Western Slope used to respond to transmountain diversion proposals.
“This is the new paradigm. It’s not the old school. In the old school it was like … we’ll see you in court,” said Jim Pokrandt of the Colorado River District, a party to the 2013 Denver Water deal.
For Denver Water, what’s called the Colorado River Cooperative Agreement provided greater certainty for its customers through means such as resolving longtime disputes regarding West Slope water. For the Western Slope, the deal meant dozens of obligations by Denver Water, such as millions of dollars in monetary payments to various entities, protections of Colorado River flows and water quality, a commitment to further water conservation and reuse efforts by Denver Water customers, and a provision aimed at helping assure maintenance of historic flows in the Colorado River even when the Shoshone Power Plant in Glenwood Canyon is not operating. That hydroelectric plant has a senior right helping control flows in the river.
Another key point in that deal is a promise that Denver Water and its customers won’t try to further develop Colorado River water without agreement from the river district and affected counties.
The cooperative agreement has 18 signatories but more than 40 partners, primarily West Slope governments, water conservation and irrigation districts, and utilities. Among them are the Ute Water Conservancy District and multiple irrigation districts in Mesa County.
Pokrandt said the 2013 deal is a win-win for both sides of the Continental Divide.
“That said, yes, more water would be moving east” if the Gross Reservoir project proceeds, he said.
The project, also sometimes called the Moffat Collection System Project, would nearly triple the capacity of the Boulder County reservoir. Denver Water is targeting water in the Fraser River, a tributary of the Colorado.
“Right now there are some periods of time when Gross Reservoir is full at its current size and their water rights are in priority but they can’t take any more water,” Pokrandt said.
The project has an estimated cost of $380 million, and Denver Water hopes to obtain the remaining major permits by the end of next year. CDPHE in June certified that the project complied with state water quality standards, and Hickenlooper endorsed it last week.
“The state’s responsibility is to ensure we do the right thing for Colorado’s future, and this project is vital infrastructure for our economy and the environment,” Hickenlooper said in a news release. “The partnerships and collaboration between Denver Water, the West Slope and conservation organizations associated with this project are just what the Colorado Water Plan is all about.”
That recently adopted plan in some respects took its lead from the Denver Water/Western Slope deal in seeking to address the state’s future water needs in a cooperative rather than confrontational manner statewide.
Pokrandt conceded that not everyone loves the Gross Reservoir proposal…
Trout Unlimited takes a more positive view of the Gross Reservoir project, pointing to its inclusion of a “Learning by Doing” program requiring monitoring of the health of the Fraser River and adjusting operations as needed. The Gross Reservoir proposal envisions drawing water from the Western Slope in wetter years and seasons, but providing the Colorado River watershed with extra water during low flow periods and investing in restoration projects.
“Moreover, Denver Water has entered into partnerships on the Front Range to ensure that the project alleviates chronic low-flow problems in South Boulder Creek. Both sides of the Divide benefit,” David Nickum, executive director of Colorado Trout Unlimited, said in a news release…
Denver Water Chief Executive Officer Jim Lochhead said in a news release, “The Denver metropolitan area is tied to the economic and environmental health of the rest of the state, and Denver Water is committed to undertake this project in a way that enhances Colorado’s values.”
Pokrandt said Western Slope water interests face the reality that under the state Constitution the right to appropriate water shall not be denied if the water can be put to beneficial use and a party can obtain the necessary financing and permitting.
“There’s not a legal stance to say no, so that’s why the river district was even formed in 1937, was to negotiate these things, because no is not an answer in the legal arena because of the Colorado Constitution,” he said.
When it comes to water rights, Pokrandt said, “in the Colorado Constitution, the Continental Divide doesn’t exist.”
This formal backing completes the state’s environmental reviews for the Moffat project, 13 years in the making, clearing the way for construction — if remaining federal permits are issued. Denver Water and opponents from Western Slope towns and nature groups reached a compromise aimed at enabling more population growth while off-setting environmental harm.
It is a key infrastructure project that will add reliability to public water supplies and protect the environment, Gov. John Hickenlooper wrote in a letter to Denver Water manager Jim Lochhead.
It “aligns with the key elements of Colorado’s Water Plan,” Hickenlooper wrote. “Denver Water and its partners further our shared vision for a secure and sustainable water future while assuring a net environmental benefit in a new era of cooperation.”
Denver would siphon 10,000 acre-feet a year, on average, more water out of Colorado River headwaters, conveying it eastward under the Continental Divide through a tunnel for more than 20 miles to an expanded Gross Reservoir southwest of Boulder. By raising that reservoir’s existing 340-foot dam to 471 feet, the project would increase today’s 41,811 acre-feet storage capacity by 77,000 acre-feet — more than doubling the surface area of the reservoir…
For more than a decade, Denver Water has been seeking permits, including federal approval for construction affecting wetlands and to generate hydro-electricity at the dam.
“During dry years, we won’t be diverting water. It is a relatively small amount of water. … It is a water supply that Colorado is entitled to develop,” Lochhead said in an interview.
The increased storage capacity “allows us to take water in wet times and carry it over through drought periods. It gives us operational flexibility on the Western Slope. … Having this additional storage enables that flexibility.”
Colorado leaders’ formal endorsement follows a recent Colorado Department of Public Health and Environment decision to issue a water quality permit for the project, certifying no water quality standards will be violated. Hickenlooper has directed state officials to work with federal water and energy regulators to expedite issuance of other permits. Denver Water officials said they expect to have all permits by the end of 2017, start construction 2019 and finish by 2024…
…Trout Unlimited and other conservation groups call the project a realistic compromise considering the rapid population growth along Colorado’s Front Range.
“If the state needs to develop more water, they need to do it in a less-damaging, more responsible way — as opposed to going to the pristine headwaters of the South Platte River, which is what the Two Forks project was going to do,” TU attorney Mely Whiting said.
“We’ve put things in place that will make Denver Water be a steward of the river,” Whiting said. The agreement hashed out between Denver Water and conservationists “does not specifically say they have to tweak the flows to help the environment. It does say they have to monitor, for water temperature and macroinvertebrates. And if there’s a problem, they are responsible for figuring out why and they need to do something about it. It does not say exactly what they have to do but they have to fix any problem.”
Gov. John Hickenlooper has officially endorsed a project to expand Boulder County’s Gross Reservoir, a move he hopes will improve Colorado’s water capacity for the next several decades.
The endorsement was considered a formality; Hickenlooper wrote to President Barack Obama four years ago, asking for the president’s help in speeding up the process for Gross and other water projects.
Colorado is predicted to face a gap of more than one million acre-feet of water by 2050, according to a 2010 estimate that many believe may be on the low end. One acre-foot of water is the amount of water it would take to cover the field at Mile High Stadium from endzone to endzone with one foot of water. That’s 325,851 gallons of water. The average family of four uses about half an acre–foot of water per year.
Hickenlooper couldn’t give his formal okay for the expansion of the reservoir, which is northwest of Eldorado Springs, until the state’s Department of Public Health and Environment had completed its review that certifies the project would comply with state water quality standards.
At 41,811 acre feet, Gross is among the state’s smallest reservoirs. It’s operated by Denver Water, supplied by water coming from the Fraser River on the west side of the Continental Divide through the Moffat Tunnel.
The expansion would allow the reservoir to collect another 18,000 acre-feet of water, enough to supply 72,000 more households per year. The estimated cost is about $380 million, which includes design, management, permitting, mitigation and construction.
The Gross expansion has been in the works for more than 13 years, with its first permits applied for in 2003. If all goes according to plan, the permitting process will be completed in 2017,with construction to begin in 2019 or 2020. The reservoir could be fully filled by 2025, according to Denver Water spokesman Travis Thompson.
In his letter to Denver Water, Hickenlooper called the Gross project key to serving more than 25 percent of the state’s population. It will “add reliability to our public water supply, and provide environmental benefits to both the East and West Slopes of Colorado,” he said.
Aye, there’s the rub: the Western Slope, whose residents fear that anything that will divert more water from the Western Slope to the Eastern Slope will cut into their water supplies. They also worry that more diversions of Colorado River water will make it more difficult to satisfy multi-state compacts with southwestern states that rely on water from the Colorado River, of which the Fraser is a tributary.
But Jim Lochhead, head of Denver Water, told The Colorado Independent that any further diversions will require buy-in from folks on the Western Slope.
It’s part of an arrangement between Denver Water and 17 Western Slope water providers that has been in development for the past six years, Lochhead said. “We’ve worked extensively with the West Slope to develop the Colorado River cooperative agreement,” which will make the environment and economy of Western Colorado better off, he said.
The agreement addresses impacts of Denver Water projects in Grand, Summit and other counties, all the way to the Colorado-Utah border.
Lochhead hopes the Gross Reservoir project will be a model for cooperation, with benefits for both sides of the Continental Divide.
And the cost? The budget for the agreement starts at $25 million and goes up from there. That first funding goes to Summit and Grand counties for enhancement projects, which includes improved water supply for Winter Park, Keystone and Breckenridge ski areas. Lochhead said the locals will figure out exactly how to spend the money, and that Denver Water isn’t dictating what those counties will do with it beyond setting some parameters for protection of watersheds, the area of land that drains to a particular body of water.
Denver Water has also committed to making improvements to the Shoshone Power Plant on the Colorado River near Glenwood Springs, and improvements to wastewater treatment plants all the way to the western state line to enhance area water quality.
“We have an extensive list of commitments to partner with the Western Slope, to do the right thing,” Lochhead said.
The Gross Reservoir expansion is critical to Denver Water’s future needs, as Lochhead sees it, because its improved capacity will allow the water utility to operate its system with more flexibility. That’s most important for Denver Water’s attention to environmental concerns, both on the Western Slope and for South Boulder Creek, which flows out of Gross Reservoir.
“The state’s responsibility is to ensure we do the right thing for Colorado’s future, and this project is vital infrastructure for our economy and the environment,” Hickenlooper said in a statement today. “The partnerships and collaboration between Denver Water, the West Slope and conservation organizations associated with this project are just what the Colorado Water Plan is all about.”
Added Lochhead in a statement Wednesday: “The Denver metropolitan area is tied to the economic and environmental health of the rest of the state, and Denver Water is committed to undertake this project in a way that enhances Colorado’s values.”
Here’s the release from Denver Water (Stacy Chesney/Travis Thompson):
Colorado Gov. John Hickenlooper has officially endorsed Denver Water’s proposed Gross Reservoir Expansion Project as a model for achieving a balanced approach to environmental protection and water supply development through an inclusive and collaborative public process.
The endorsement follows the Colorado Department of Public Health and Environment’s issuance of a Section 401 Water Quality Certification on June 23, 2016, which ensures compliance with state water quality standards. The certification confirms that Denver Water’s commitment to extensive mitigation and enhancement measures for the project will result in a net environmental benefit.
“The state’s responsibility is to ensure we do the right thing for Colorado’s future, and this project is vital infrastructure for our economy and the environment,” said Colorado Gov. John Hickenlooper. “The partnerships and collaboration between Denver Water, the West Slope and conservation organizations associated with this project are just what the Colorado Water Plan is all about.”
The Gross Reservoir Expansion Project — also known as the Moffat Collection System Project — will strengthen Denver Water’s system against drought and climate change by nearly tripling the capacity of Gross Reservoir, located in Boulder County.
“Colorado is a growing and dynamic state,” said Denver Water CEO Jim Lochhead. “Denver Water has the critical responsibility to sustain over 25 percent of the state’s population and the majority of our economy for decades to come.”
Since 2003, Denver Water has been involved in federal, state and local permitting processes to evaluate the proposed project and develop ways to not only mitigate identified impacts, but also to enhance the aquatic environment and the economy of Colorado. The 401 certification — one of the major regulatory requirements — recognizes and builds upon other existing Denver Water agreements such as the landmark Colorado River Cooperative Agreement, Learning by Doing cooperative effort and the Grand County Mitigation and Enhancement Coordination Plan.
“The Denver metropolitan area is tied to the economic and environmental health of the rest of the state, and Denver Water is committed to undertake this project in a way that enhances Colorado’s values,” said Lochhead.
Denver Water expects to secure all of the major permits for the project by the end of 2017. The estimated cost of the project is about $380 million, which includes design, management, permitting, mitigation and construction.

The Grand County Learning By Doing Cooperative Effort (LBD) is a unique partnership of East and West Slope water stakeholders in Colorado.
LBD emerged from the Colorado River Cooperative Agreement, a five-year negotiation that became effective in 2013 and will be fully implemented with the successful construction of the Moffat Collection System and Windy Gap Firming Project. The agreement establishes a long-term partnership between Denver Water and Colorado’s West Slope, including several water utilities, nonprofit organizations and government agencies.
A Governance Committee oversees the LBD activities, with one voting member from each of these organizations:
Colorado Parks and Wildlife
Colorado River District
Middle Park Water Conservancy District
Northern Colorado Water Conservancy District
A Technical Committee, made up of representatives from the Governance organizations, as well as government agencies, regional water utilities and other partners, advises on LBD efforts and activities.
LOVELAND – Mike King, the new director of planning for Denver Water, said at a recent meeting that beyond additional transmountain diversions through the Moffatt Tunnel into an expanded Gross Reservoir near Boulder, Denver Water doesn’t have other Western Slope projects on its radar.
King served as executive director of Colorado’s Department of Natural Resources from 2010 until January of this year, when he took the planning director job with Denver Water.
After speaking to a luncheon crowd of close to 200 at the Northern Water Conservancy District’s spring water users meeting in Loveland on April 13, King was asked from the audience “How much more water does Denver Water need from the Western Slope?”
“I think if we get Gross Reservoir approved, the answer is for the foreseeable future, you know, we need to do that first,” King said.
King is a native of Montrose, son of a water attorney, and has a journalism degree from CU Boulder, a law degree from the University of Denver, a master’s in public administration from CU Denver and 23 years of state government experience.
“And I can tell you that the reality is, whether it is from a permitting perspective or a regulatory perspective, the West Slope is going to be a very difficult place,” King continued. “If there is water available, it is going to be a last resort. And I so think that the answer is, that won’t be on our radar.”
Denver Water is seeking federal approval to raise the dam that forms Gross Reservoir, in the mountains west of Boulder, by 131 feet. That would store an additional 77,000 acre-feet of water and bring the reservoir capacity to 118,811 acre-feet. Ruedi Reservoir, by comparison, holds 102,373 acre-feet.
The $360 million project would provide 18,000 acre-feet of firm yield to Denver Water’s system and result in an additional 15,000 acre-feet of water being diverted from the West Slope each year. On average, Denver Water’s 1.3 million customers use about 125,000 acre-feet of West Slope water each year.
The water to fill an expanded Gross Reservoir would mainly come from tributaries of the Fraser and Williams Fork rivers, via the Moffat Tunnel, near Winter Park.
Beyond the Gross Reservoir project, King explained that any future Denver Water projects on the West Slope would need to fit within the confines of the Colorado River Cooperative Agreement, signed by Denver Water and 17 West Slope entities in 2013.
The CRCA, says that “if there is more water, it only comes after the West Slope says they agree with it and it makes sense,” King said. “That sets the bar so incredibly high and gives them the ultimate ability to say, ‘This is good for the West Slope.’
“And so I just don’t think Denver Water is going to be looking to the West Slope,” King continued. “I think anybody who manages natural resources, and water in particular, will never say ‘never’ to anything, but I think it is certainly not on our radar.”
Not on Denver Water’s radar, perhaps, but it is worth noting that Denver Water is the only major Front Range water provider to have signed the cooperative agreement with the West Slope.
When asked what he thought of King’s remarks about West Slope water, Eric Kuhn, the general manager of the Colorado River District said he thought the comments reflect “the concept that if Denver takes more water from the West Slope it could undermine the security/reliability of what they already take.”
Kuhn’s comment relates to the possibility that if Denver Water diverts too much water from the Western Slope, it could help trigger a compact call from the lower basin states, which could pinch Denver’s transmountain supply of water.
Editor’s note: Above is a recording of Mike King, the director of planning for Denver Water, speaking after lunch in front of about 200 people at Northern Water’s spring water users meeting, a public meeting held at The Ranch event center in Loveland on Wednesday, April 13, 2016. The recording, made by Aspen Journalism, begins shortly after King had begun his remarks. It is 26:34 in length. At 8:20, King discusses the development of the Colorado Water Plan. At 22:40, King answers a question about the governor’s endorsement of the Windy Gap project and another phrased as “How much more water does Denver Water need from the Western Slope?”)
A buoyant crowd
Earlier in the meeting engineers from Northern Water — which supplies water to cities and farms from Broomfield to Fort Collins — told the mix of water providers and water users from northeastern Colorado that they could expect an average spring runoff this year, both from the South Platte and the Colorado Rivers.
They were also told that Northern Water was making progress on its two biggest projects: the Windy Gap Firming Project, which includes construction of Chimney Hollow Reservoir near Berthoud; and NISP, the Northern Integrated Supply Project.
NISP includes two new reservoirs, Glade and Galeton, to be filled with East Slope water from the Cache La Poudre River, which runs through Fort Collins and into the South Platte River.
Just before lunch, John Stulp, the special policy advisor on water to Gov. John Hickenlooper, read a surprise letter from the governor endorsing the Windy Gap project, which would divert an additional 9,000 acre-feet of water each year, on average, from the upper Colorado River and send it through a tunnel toward Chimney Hollow.
Windy Gap is part of the Colorado-Big Thompson Project, which diverts on average 260,000 acre-feet a year from the Western Slope.
The Windy Gap project does include environmental mitigation measures for the sake of the Colorado River, and has approval from the required state agencies and Grand County, but it still needs a permit from the U.S. Army Corps of Engineers.
A political risk
After lunch, King shared some insights from his old job as head of the state’s department of natural resources.
“I think it’s important that you understand what the development of the state water plan looked like from the governor’s perspective and the state’s perspective,” King told his audience.
As head of DNR, King had oversight over the Colorado Water Conservation Board, which was specifically tasked by the governor in late 2013 to produce the state’s first-ever water plan, and to do so in just two years.
King said that he, Stulp and the governor knew that a water plan in Colorado could be “the place where political careers went to die.”
“So the thing we had to make sure that came out of this, knowing that we weren’t going to solve the state’s water issues in two years, was that we had to do this in a manner that politically, this was viewed as a big win, and that future governors and future elected officials would say, ‘We need to do this again and we need to continue this discussion,’” King said.
“Not because the governor needed a political win,” King added, “but because to have the next stage of the water plan, to have the discussion in five years, you can’t have an albatross around this, and I think we were able to do that, and so we’re very proud of that.
“If we had a political mushroom cloud, no one would have ever touched the Colorado Water Plan again,” King continued. “That meant we aimed a little bit lower than maybe we would have liked, and I’ve gotten this at Denver Water, talking about lost opportunities in the Colorado Water Plan. Maybe we did aim just a little bit lower than we should have.”
King said the state was not able to “reconcile the inherent conflicts” in the various basin implementation plans, or BIPs, that were put together by regional basin roundtables as part of the water planning process.
And he acknowledged that the plan has been criticized for not including a specific list of water projects supported by the state, and for reading more like a statement of problems and values than a working plan.
“One of things that has been driven home to me time and time again in the two months that I’ve been at Denver Water is that planning is not something you do every five or six years,” King said. “Planning is a continuous process.”
King also said that there were some “tremendous successes” in the water plan, including the basin implantation plans, or BIPs, even though they sometimes conflicted.
“We got BIPs from every single basin,” King said. “The basins turned over their cards and said ‘This is what we need.’ So now we have a major step forward.”
Other plan elements
King said other successes in the Colorado Water Plan include the stated goal of conserving 400,000 acre-feet of water by 2050 and a nod to changing land use planning in Colorado.
King said tying land use to water availability “was something we never discussed in Colorado because it infringed on local control and it was just kind of a boogieman in the room.”
But he pointed out that “the vast majority of the basin implementation plans said, expressly, ‘We need to have this discussion’ and ‘We need to start tying land use to water availability,’” King said. “That’s a good thing. That’s a major step forward.”
When it comes to land use and Denver Water, King said driving down the per capita use remained a high priority and that if Denver proper grows, it is going to grow up through taller buildings, not by sprawling outward.
King also said Denver Water was working to manage, and plan for, the already apparent effects of climate change, especially as spring runoff is now coming earlier than it used to.
“We know that the flows are coming earlier, we know that the runoff is coming earlier,” King said, noting that reality is causing Denver Water to plan for different scenarios and ask questions about storage and late summer deliveries of water.
“For us, the most immediate thing is, is that we know it’s getting warmer,” King said. “In the last 20 years we’ve seen that, the way the [run offs] are coming earlier. We know we’ve had catastrophic events that are incredibly difficult for us to manage. And so we’re trying to work through that.”
