Fraser River health should improve some with Moffat Collection System Project

The plan includes environmental enhancements and protections to ensure the Fraser River will be better off with the Moffat Project than without it.

Here’s a guest column from Kirk Klancke that’s running in the Boulder Daily Camera:

As a long-time resident of Grand County, I’ve been disappointed by recent articles in the Camera about the Moffat Firming Project permit and especially about the west slope implications of the project. Coverage has been misleading in highlighting potential negative environmental impacts while ignoring the stream habitat improvements and flow benefits in the permit that will actually improve the health of the Upper Colorado River system.

It’s important for readers to get the total picture in weighing the environmental impacts of the project.

Trout Unlimited is also a group “dedicated to protecting and restoring the Colorado River” — and we’ve spent more than a decade closely following the proposed Moffat project and working to protect the Upper Colorado. Then, a couple years ago, TU helped negotiate a settlement with Denver Water and local stakeholders in Grand County that included tough permit requirements that we believe will best protect the Upper Colorado and Fraser Rivers.

It’s true that the Moffat project will increase total diversions from the Colorado headwaters. But the project will also provide significant help to rivers and streams currently impacted by transmountain diversions, including streams diverted to meet Boulder’s water supply (through the Windy Gap project). Under terms of their permit, Denver Water must undertake mitigation and enhancement measures that will actually improve the health of streams.

For instance, as part of its commitments, Denver Water will manage diversions to help provide needed flushing flows on the Fraser and its tributaries, complete habitat and native trout restoration work in the Williams Fork basin, and contribute funds toward projects like the Fraser Flats restoration project that is already underway to improve stream and riparian habitat.

Most significantly, Denver Water will participate in an ongoing adaptive management program called “Learning by Doing” through which Denver, Grand County, Trout Unlimited and other local stakeholders are cooperating to apply mitigation and enhancement resources, monitor river and watershed conditions and make adjustments to achieve the best results over time. These efforts were launched even before Denver received their federal approvals.

While my efforts have focused on Grand County, I know that Denver Water has looked for partnerships on the east slope as well. For example, as part of the project, they will provide 5,000 acre-feet of storage in the enlarged reservoir for Boulder and Lafayette to use in providing in-stream flows at critical times, to keep downstream stretches of South Boulder Creek healthy and flowing.

Denver Water’s plans to enlarge Gross Reservoir certainly will have significant impacts on Boulder County, including disruption to lives and property around the reservoir area during construction — but these are mostly temporary impacts. It’s important to look at the project’s long-term benefits to our rivers and streams as well as to our water security.

For years I saw Denver Water as my community’s public enemy number one. But in recent times Denver Water has demonstrated a willingness to work as a partner to keep the Upper Colorado River healthy. This collaboration among stakeholders represents the best opportunity to protect and preserve the Upper Colorado River into the future.

Indeed, it’s already working.

Gross Reservoir Expansion Project update

From The Summit Daily News (Kevin Fixler):

The U.S. Army of Corps of Engineers officially threw its support behind the proposed expansion of Denver Water-owned Gross Reservoir, aka the Moffat Collection System Project, to triple capacity of the storage facility this past Friday. The review process has been nearly a decade and a half in the making as the Front Range tries to keep pace with population and expected water consumption growth by pulling more of the resource off the Colorado River in headwater communities along the Western Slope.

Just to reach the milestone and obtain buy-in from the region, Denver Water spent six years in negotiations with Summit, Grand and Eagle counties and 14 other stakeholders, as well as several other subsidiary entities. The result was the Colorado River Cooperative Agreement, which gave way to the impacted counties accepting the terms to allow the metro area’s municipal water agency to remove water to which it already owned the rights.

“While some may say 14 years is too long, I believe complicated issues deserve thorough study,” Jim Lochhead, Denver Water CEO and manager, said in a news release. “In accordance with other agreements we’ve implemented along the way, Denver Water will provide millions of dollars to improve watershed health in the critical Colorado and South Platte River Basins. The project enjoys broad, bipartisan support from lawmakers, major environmental groups, chambers of commerce and water interests on both sides of the Continental Divide.”

An environmental group that does not share in the reverie, however, is Save The Colorado, a nonprofit water advocacy organization against the project to divert 15,000 more acre-feet of water from the Colorado River…

Save The Colorado’s attorneys are presently reviewing the Army Corps’ record of decision in anticipation of a suit to be filed in federal district court in Denver as part of a larger coalition that may include Boulder homeowners who live around the reservoir’s perimeter. A requested injunction may be part of the legal strategy should Denver Water begin construction on the 131-foot heightening of the existing 340-foot dam wall if a few other smaller-scale permits are secured, but the aim is preventing it from ever coming to fruition.

“Our goal is stop the project, not slow it down,” said [Gary] Wockner…

Summit’s Board of County Commissioners believes the complex deal is a fair one, considering what the area’s water future may have looked like without it in place. Aside from other considerations to keep Denver Water’s appetite in check in the years to come, $11 million in cash — $2 million of which has already been paid — will ultimately be split evenly among the county government and its four major towns of Breckenridge, Dillon, Frisco and Silverthorne for future water and other environmental enhancement projects.

Various county entities, including Summit’s four ski resorts, also stand to receive access to a combined 1,700 acre-feet (approaching 570 millions of gallons) of water annually not previously available out of Denver Water-owned Dillon Reservoir. Grand County is to receive $6 million in payments upon the bypassing of possible legal barriers and final execution of all permits, on top of additional water and adaptive management assistance, while Eagle received some legal assurances of its own.

“This agreement provides for our economy, our environment, our way of life and are things we could have never gotten had we fought Denver Water in court,” said County Commissioner Thomas Davidson. “Denver Water already had these water rights, and that was something we from the Western Slope had to keep reminding ourselves of. Each side had to give up or give in on things they felt very passionately about not wanting to give up.”

With some exceptions, the compromise also better defines Denver Water’s service area to help prevent the expansion of those boundaries and the thirst for even more regional waters. The agency has committed to maintaining conservation activities and increasing reuse of water from the Blue River to reduce the need for more Western Slope water as part of these efforts. A guarantee to hold Dillon Reservoir at an accepted level for ideal aesthetic and recreational purposes from June 18 to Labor Day is a guarantee written into the agreement as well.

With the Army Corps’ endorsement as follow up to a prior certification granted by the Colorado Water Quality Control Division, Denver Water next needs a few remaining approvals from the Federal Energy Regulatory Commission, U.S. Forest Service and most likely a permit from Boulder’s Board of County Commissioners.

Denver Water is seeking approvals from the U.S. Army Corps of Engineers, the U.S. Fish and Wildlife Service, and the state of Colorado to expand Gross Reservoir, which is southwest of Boulder. The 77,000 acre-foot expansion would help forestall shortages in Denver Water’s water system and offer flood and drought protection, according to Denver Water.

From The Denver Post (Danika Worthington):

Denver Water CEO Jim Lochhead said the project, which was approved late Friday, was important to add balance and resiliency to the agency’s system. The dam expansion still needs approval from the Federal Energy Regulatory Commission to increase its hydropower capacity.

“It’s been a long haul,” Denver Water Board President Paula Herzmark said of Friday’s decision. “We are just ecstatic, just elated that this permit is now in place and we can begin. To have the insurance that we’re going to have this additional source of supply as our community grows.”

Colorado Trout Unlimited was happy with the news. The group has been working with Denver Water to make the project environmentally friendly, Trout Unlimited counsel Mely Whiting said.

The project includes an environmental pool to divert water to streams that need it. It also led to the Learning By Doing Cooperative Effort that brings together groups to monitor stream conditions and quickly take action when needed. Denver Water is also giving about $25 million to Grand County and other counties for environmental advancements…

Lochhead countered that the extra water will be needed as current conservation efforts won’t be enough to cover the growing population and effects of climate change. He added that Denver Water has been working with environmental groups and local and federal governments since the start to not just mitigate damage, but rather improve rivers.

Lochhead acknowledged that the five years of construction will be hefty, especially the three years of intensive concrete placing. He said Denver Water worked with the local residents to mitigate impacts and said an onsite quarry will be built to reduce truck trips.

“With a warming climate and with growth and other issues in our system, we need to make sure that our system is resilient in the long term,” he said.

From The Jackson Hole News & Guide (Allen Best):

Denver Water finally has a key permit that it needed to begin raising Gross Dam, located in the foothills northwest of Denver. The purpose is to triple the amount of water that can be stored there, including greater volumes of water diverted from the Winter Park area.

But the city still needs several more federal permits and may get caught in a legal fight. Unlike some water battles of the past, however, this one will come from elsewhere along the Front Range…

Denver Water has been working on this plan since the great drought of 2002 caused city water officials to realize the vulnerabilities of their system. The agency provides water not only to Denver, but many suburbs — altogether about a quarter of all Colorado residents.

“While some may say 14 years is too long, I believe complicated issues deserve thorough study,” said Jim Lochhead, Denver Water chief executive.

Denver has diverted water from the Fraser River and its tributaries since 1936 through the pioneer bore of a railroad tunnel under the Continental Divide. The water is impounded at Gross Dam. The dam already stands 340 feet tall, and Denver wants to raise the dam another 131 feet, to accommodate increased diversions.

Grand County, whose water will be diverted, has not opposed the project…

These diversions were mostly engineered in the 1930s. “Denver had a vision; we had none,” summarized Lurline Curran, who is the now-retired county manager of Grand County, at a water conference about a decade ago.

This time, Grand County sat down with Denver and brokered a deal. Denver gets more water, but it also agrees to work with Trout Unlimited and other local groups to try to take the water in ways that are least impactful to fish and other components of the ecosystem.

Army Corps of Engineers approves Gross Dam expansion — @DenverWater

The Gross Reservoir Expansion Project will add 77,000 total acre feet — 72,000 for Denver Water use and 5,000 for an environmental pool that provides additional water for South Boulder Creek during low-flow periods — nearly tripling reservoir capacity.

Here’s the release from Denver Water (Stacy Chesney):

Army Corps of Engineers issues record of decision and 404 Permit

Following 14 years of careful study, evaluation and deliberation, the Army Corps of Engineers has approved Denver Water’s request to raise Gross Dam in Boulder County. The additional water stored in Gross Reservoir will help prevent future shortfalls during droughts and helps offset an imbalance in Denver Water’s collection system.

The approval comes in the form of a record of decision and 404 Permit — two documents required by the federal government as part of the National Environmental Policy Act.

“Denver Water appreciates the Corps’ dedication and commitment to careful study of the anticipated impacts of this project,” said Denver Water CEO Jim Lochhead. “We will complete this project responsibly, as evidenced by our actions during the public process and the resulting robust environmental protections we’ve agreed to along the way. We’re proud to be doing the right thing.”

The existing dam was built in the early 1950s and was designed to be expanded in the future to increase water storage capacity. The Gross Reservoir Expansion Project approval completes this original vision.

Expanding Gross Reservoir is a major part of Denver Water’s long-term plan to deliver safe, reliable water to the people it serves now and into the future. The project is part of Denver Water’s multi-pronged approach that includes conservation, reuse and responsibly sourcing new supply.

“Issuance of this permit will unlock significant resources that will allow us to do good things for the river and the environment,” said Mely Whiting, counsel for Trout Unlimited.

In accordance with existing agreements, including the Colorado River Cooperative Agreement and Grand County’s Learning By Doing, and conditions in the 404 Permit, Denver Water will provide millions of dollars to improve watershed health in the critical Colorado and South Platte River Basins. Lochhead said these commitments are one reason that last year Colorado Department of Public Health and Environment found that the project will have a “net environmental benefit” on the state.

The project has earned key endorsements from Gov. Hickenlooper, state and federal lawmakers, major environmental groups, local mayors and city councils, chambers of commerce and economic development corporations, county elected officials and water interests on both sides of the divide.

“The next milestone we anticipate is approval by the Federal Energy Regulatory Commission of Denver Water’s hydropower license amendment application at some point next year,” said Jeff Martin, Gross Reservoir Expansion program manager. “In the meantime, Denver Water continues to make significant investments in setting a firm foundation for the project’s overall success by recently hiring Black and Veatch as the owner’s representative. We are also in the process of procuring a design engineer.”

Preconstruction activities, including dam design and geotechnical work, are expected to begin in 2018. The entire project is expected to be completed in 2025.

@DenverWater is running water in the @COHighlineCanal after headgate replacement

Highline Canal Denver

From TheDenverChannel.com (Connor Wist):

Water is flowing through parts of the 71-mile High Line Canal for the first time since May 2015. Denver Water is sending water down the canal from the South Platte River after replacing a 130-year-old diversion dam in Waterton Canyon.

In 2015, Colorado experienced a high spring runoff that destroyed the dam sitting 1.5 miles up the canyon. The wooden structure built between 1880 and 1883 washed away in the runoff. Denver Water successfully replaced the High Line Canal diversion structure in 2016.

Denver Water typically only runs water to the canal, with an 1879 water right, periodically from April to October. The water runs depend on the availability of South Platte River water and demand from irrigation customers. With the new dam complete, Denver Water is able to send water to the canal once again with the current conditions…

The High Line Canal starts in Douglas County at Waterton Canyon and runs to Green Valley Ranch in northeast Denver. The path of the canal falls within one mile of hundreds of thousands of residents.
