Michigan Ditch: “the biggest excavators we could bring in were nearly hanging off the edge of the mountain on the way up” — John Beckos

From TrenchlessTechnology.com (Jim Rush):

The Michigan Ditch is a 5.2-mile conveyance system that brings water from the high mountains into the Joe Wright Reservoir, a part of City’s two water sources. Over the years, the Michigan Ditch, a combination of pipeline and open channel originally built around 1900 and purchased by Fort Collins in the 1970s, was subject to the whims of Mother Nature. Specifically, one portion of the water supply route that crosses an area known as “the mudslide” was subject to periodic damage when the slides occurred.

The City was accustomed to making simple repairs that involved digging up the pipe and moving or replacing it when the slide moves. But in September 2014, crews noticed something unusual. The pipe, which typically moved only during snowmelt in the spring, had moved substantially since its repair that summer. The following spring, even more movement showed that a more permanent fix was needed.

“It was apparent that this wasn’t something we could simply dig up and put back in place like previous years,” said Owen Randall, chief engineer for Fort Collins Utilities. “We knew we needed a long-term solution that could cost upwards of $10 million. When I told City management the response was: ‘The water is worth $180 million, so go fix it.’”

In summer 2015, the City got to work with a geotechnical assessment that included seismic refraction as well as vertical and horizontal borings. Meanwhile, the City put together a team of consultants and contractors to help ascertain the best way to move forward. After exploring the options, the team decided that a tunnel that would re-route the water through the mountain in stable rock was the best solution…

The tunnel option provided the long-term solution the City was looking for while having the added benefits of less maintenance, less environmental impact and a construction cost comparable to other options…

The logistics of working on the side of a mountain also presented challenges. The project site was located 2.5 miles up a narrow, winding dirt road that dictated the weight and dimensions of the equipment that could be safely transported. Additionally, the nearest town (Walden, Colorado; population 3,000) was located 30 miles away, with Fort Collins 70 miles away. Even cell phone service had to be brought in.

“Due to the nature of the road, we were limited to about an 11-ft wide load,” said John Beckos, project manager for BT Construction. “We were unable to get a crane to the site, and the biggest excavators we could bring in were nearly hanging off the edge of the mountain on the way up.”

The site access also dictated the type of tunnel boring machine that could be used to excavate the tunnel. After evaluating the options, the project team elected to use an Akkerman hard-rock TBM that had a mixed face cutterhead to deal with the highly fractured, hard rock and abundant fault and shear zones. The machine was compact enough to accommodate the limited space at both the launch and retrieval pits, light enough to be handled by the available equipment, and had enough power to drill through rock that reached strengths of 15,000 psi…

The tunnel was mined from the downstream portal to the upstream portal. The first 40 ft of the alignment was straight before it transitioned into the 630-ft radius curve spanning 726 ft. The TBM was equipped with a conveyor system and dual muck boxes to remove the spoil. Spoil was stockpiled near the site to be used by the City for future repairs to the ditch and pipeline, as well as the access road, which the City also maintains…

Randall said the ground made tunneling a challenge. “The only thing consistent about the ground was that the rock was inconsistent,” he said. “We would find hard zones 2-3 inches thick, 2-3 feet thick and 30-feet thick. We knew we were going to get into difficult geology, but it still posed a challenge.”

Once the TBM was completely launched into the mountainside, the team had originally planned to be tunneling for about 6 weeks from early July through the middle of August. The inconsistent rock in the middle of the drive would end up slowing productions down and delaying the hole out until Sept. 29. And, despite the challenging ground, the TBM holed through precisely on target. Project team members credited the VMT guidance systems, typically used for larger and longer tunnels, for keeping the tunnel on line and grade…

Over the last 20 years, Fort Collins has implemented and refined its delivery system known as the Alternative Product Delivery System (APDS). Fort Collins retains a group of prequalified contractors and consultants on an annual contract basis – known as master service agreements – and when a project is needed, the City can call on its team of service providers with expertise in a particular area to negotiate a contract. This allows the City to quickly gather a team to develop the project from start to finish.

In the case of the Michigan Ditch Tunnel, the project team was brought on board to determine the best solution for the problem. As the project began to take shape as a tunnel, the City negotiated further contracts for tunnel design, construction and TBM procurement. The project team additionally developed a risk register to help identify and mitigate potential occurrences that could impact the project.

“Rather than trying to write a contract for the whole project up front, we can write contracts that are very well defined, knowing what our scope of work is going to be as planning and design progresses,” Randall said.

The added benefit of having the project team in place was that the project goals were defined by the team, rather than by an individual party or parties. “This was a very challenging and difficult project, but when you have everybody working toward the same goal, it makes all the difference in the world,” Randall added.

“The team functioned at a very high level and with great communication,” Dornfest said. “It was extremely challenging, but there was never any finger pointing and we were able to get the job done on schedule and under budget.”

Thanks to planning, teamwork and determination, the Michigan Ditch Tunnel project was successfully completed approximately $1 million below the initial budget of $8.5 million. The ditch system is now back online, assuring Fort Collins citizens of a reliable source of water for the years to come.

Here’s the release from Colorado State University (Jim Beers):

The Cache la Poudre River, which flows from the mountains through Fort Collins, Timnath and Windsor to the plains east of Greeley, is at the heart of countless activities: from irrigating crops and lawns to providing drinking water for more than 365,000 people and hosting numerous recreational activities.

Those with connections to and concerns for the Poudre River will gather on Friday, Feb. 3 for the fourth annual Poudre River Forum. After its first three years at Larimer County Fairgrounds, the forum is moving down the river to Greeley as a reminder that the Poudre River is important to all who benefit from it — from its headwaters to its confluence with the South Platte. This year’s forum — the theme is “As the Poudre Flows — Forest to Plains” — will be held from 8:30 a.m.-4:30 p.m. at the Island Grove Events Center, 501 N. 14th Ave., Greeley. Pre-registration is required for all participants.

Understanding the river, each other

Sponsored by the Poudre Runs Through It Study/Action Work Group, the forum serves as a community-wide gathering of people from agricultural, municipal, business, recreational and environmental backgrounds to learn about and discuss issues related to the Poudre River.

“The Poudre River Forum brings together those who use the river for agricultural and urban diversions and those who work to improve its ecological health. In the past those groups have not necessarily seen eye to eye,” said MaryLou Smith, PRTI facilitator. “Increasingly our participants are open to the idea that it takes collective vision and action to make the Poudre the world’s best example of a healthy, working river.”

Once again, this year’s event will be facilitated by the Colorado Water Institute at Colorado State University. “The Forum is a great opportunity for the communities connected by the Poudre River to come together to better understand the entire watershed, and each other,” said Reagan Waskom, director of CWI.

Forests and water quality/quantity

Laurie Huckaby with the U.S. Forest Service, will present “The last 1,000 years in the Poudre according to the trees,” to kick off the topic of how important the upper watershed is to water quantity and quality.

“Water quality and forests are inextricably linked,” said Joe Duda of the Colorado State Forest Service, who will join Huckaby as one of the presenters. “Forest conditions and insects, disease and fire all can have profound impacts on water flow and quality. Only healthy, resilient forests can continuously supply clean water.”

Global lessons for local success

“Finding the Balance: Managing Water for People and Nature” is the message of keynote speaker Brian Richter. Richter has been a global leader in water science and conservation for more than 25 years, and currently serves as chief scientist for the Global Water Program of The Nature Conservancy in Washington D.C. Richter’s ideas about the importance of recognizing the balance of working river/healthy river are the basis for which PRTI was initially formed. He has consulted on more than 120 water projects worldwide, and has served as a water advisor to some of the world’s largest corporations, investment banks, the United Nations, and has testified before Congress on multiple occasions. Richter co-authored,with Sandra Postel, the 2003 book Rivers for Life: Managing Water for People and Nature and in 2014 wrote Chasing Water: A Guide for Moving from Scarcity to Sustainability.

Change affects all sectors

An afternoon panel session will probe the impacts of change — positive and negative — along the Poudre River and how they have been similarly and differently addressed by agriculture, urban, and environmental sectors. They will discuss what anticipated future changes might these three sectors see as opportunities or incentives for mutually beneficial collaboration that could result in a healthier, working river?

“It has been said that the only thing that is constant is change,” said John Bartholow, retired ecologist from U.S. Geological Survey, and panel coordinator/moderator. “The question is, can we learn to adapt to those changes sure to come on the Poudre in ways that benefit agriculture, municipalities, and the environment?”

The panel will include Eric Reckentine, deputy director, City of Greeley Water and Sewer; John Sanderson, director of science, Nature Conservancy of Colorado; and Dale Trowbridge, general manager, New Cache la Poudre Irrigating Company.

Videos, displays and music too

The day-long forum also includes “River Snapshots” highlighting more than 15 projects undertaken by a variety of groups on the Poudre last year; “My How the Poudre Has Changed,” featuring historical 1970’s footage of the Poudre; updates from both the cities of Greeley and Fort Collins on current water programs; and over two dozen river-focused displays from community organizations and agencies. The day concludes with a social hour including food, beer and other beverages, and river-themed door prizes.

Registration is $50 and includes lunch. Scholarships for students and reduced rates are available. The deadline to register is Friday, Jan. 27 at http://prti.colostate.edu/forum_2017.shtml.

From The Fort Collins Coloradoan (Jacy Marmaduke):

It never looked like a blizzard outside, but three straight days of snow landed Fort Collins with upwards of 9 inches in the city’s northern reaches and at least 7 inches everywhere else by the end of Thursday. That makes it the biggest snow storm Fort Collins has seen this season and pushed the city above its average for this time of year.

“Water storage is ‘integral’ to Fort Morgan’s future” — Ron Shaver

Northern Integrated Supply Project July 27, 2016 via Northern Water.

From The Fort Morgan Times (Jenni Grubbs):

A community that does not have enough water is a community that does not survive, and Fort Morgan city leaders want to ensure that is not what happens here.

As such, the Fort Morgan City Council approved continuing the city’s role in the Northern Integrated Supply Project and the $360,000 expenditure that will require in 2017.

Fort Morgan has been gambling on NISP, a massive water storage project, getting permitted and built for 13 years now, according to Water Resources/Utilities Director Brent Nation.

But it’s a gamble that could pay off in water security for as long as the next five decades, according to City Manager Jeff Wells.

About NISP

That’s because NISP would include Northern Colorado Water Conservancy District (aka Northern Water) building both Glade Reservoir north of Fort Collins and Galeton Reservoir northeast of Greeley and east of Ault.

If these reservoirs get built, it would mean “40,000 acre feet of new, reliable water supplies” for the 15 NISP participants, which include Fort Morgan, Morgan County and Morgan County Quality Water District.

But getting it built involves both completion of the final environmental impact statement for he project and getting a record of decision on a permit from the U.S. Army Corps of Engineers.

As of January 2017, Northern Water was estimating that the Corps likely will finish the FEIS yet this year and then issue the record of decision on the permit sometime in 2018.

Large cost, lengthy timeline

Fort Morgan, alone, will have spent more than $1.3 million toward NISP and the city’s 9 percent stake in it over the project’s 13 years of planning and studies. And there could be another 10 to 12 years yet to go before NISP and its reservoirs conceivably would go online and the city would have water stored in Galeton Reservoir and pumped back to Fort Morgan.

As the project progresses, the city’s annual payments for it will get larger and larger, Nation warned. He called the 2017 one among the last of the “smaller payments.”

Depending upon what the Corps does this year, the larger NISP payments could start next year.

“Next year, in 2018, we’ll start moving into the larger engineering payments, and then hopefully within a year or two after that we’ll be moving into construction-type payments, where we’re getting into millions of dollars for our portion of that work,” Nation said.

Regardless, if and when it does get built, NISP would provide enough water to give the city water security for the future and whatever residential, commercial and industrial growth may come, according to Mayor Ron Shaver, Wells and Nation.

And such a lengthy timeline is not unusual for this large of a water storage project, according to both Nation and officials from Northern Water.

Reasons to continue

But continuing to support it will be worth it for the city in the long term, Nation stressed.

He shared his reasons why the city should “move forward on this project” with the council.

“We continue to exist on a base water supply that we have to rent what we need for our current needs. We still have times of the year where we’re using some rental C-BT water in order to meet all of our water demands,” Nation said.

Also, the Fort Morgan Water Treatment Plant is experiencing record levels for demand for treated water, with 1.5 billion gallons treated over the last 12 months.

“Six out of the last seven months we had record production at treatment facility,” Nation said, adding that the local industry was “driving those numbers.”

Specifically, large industrial water customer Cargill Meat Solutions is continuously pulling in water.

“We’re not seeing a lot of downtime with Cargill,” Nation said. “And even when they’re down on that seventh day, they’re using a lot of water just to clean the facility.”

And expansions at both the Leprino Foods cheese plant and the Western Sugar Cooperative beet plant have meant increased demand for water from Fort Morgan.

“We just continue to see our industrial/commercial numbers go up as we continue just to exist at the current population that we’re at,” Nation said. “It kind of drives home to me that this project is important to us. It’s something that we need to continue to participate in and see it to the finish line. This is something we need as a community.”

Wells agreed, adding that the city has previously looked into many other options for obtaining enough water for the city’s future.

“Today, there are no more viable alternatives than NISP for the city of Fort Morgan,” he said.

Shaver, who served as the city’s utilities director before retiring from the city and then serving on the council and now as mayor, said NISP is what the city needs for its future.

From The Loveland Reporter-Herald (Pamela Johnson):

This year, actual work will begin to repair habitat along and inside several stretches of the Big Thompson River through a grassroots group, The Big Thompson Watershed Coalition, that formed after the 2013 flood.

“2017 is going to be a big year for projects happening on the ground,” said Shayna Jones, watershed coordinator with the coalition. “We’re talking millions of dollars in river restoration.”

A couple of projects through the coalition have already begun, but several others are going to kick off in 2017. Early in the year, the coalition will put out bids for a contractor to work on a stretch about a mile long from Jasper Lake through Narrows Park, which is in the lower section of the canyon.

Estimated to cost $900,000, the project will include stabilizing sections of the banks, planting vegetation and creating what are called flood plain benches to allow the water space to spread out in the event of a future flood, explained Jones and Tracy Wendt, assistant watershed coordinator.

The work also includes improving fish habitat in several ways, such as building pools within the river and planting vegetation in strategic places to provide shade and cover.

“There will be habitat improvements for all different life stages of trout,” Wendt said. “It’s all the phases of their life to help them.”

Because of the fish habitat component, the coalition, in partnership with Rocky Mountain Flycasters, recently received a $4,500 grant from the Trout and Salmon Foundation. And the Flycasters, a local chapter of Trout Unlimited, also contributed $2,000 to the project.

The bulk of the funding, about $500,000, will come from the Natural Resources Conservation Service with the rest of the money from the Colorado Water Conservation Board, Jones explained.

This piece of the river winds through both private and public properties and ends just before the Narrows near the Colorado Cherry Company.

Other projects also are planned further west along the river with more money coming from the NRCS and the Colorado Water Conservation Board. The exact amounts of money and grants are still being finalized, though Jones did confirm the total work would be in the millions.

Other projects to rehabilitate the river and river corridor are occurring simultaneously including one that will begin in 2017 as a partnership with the coalition and Sylvan Dale Guest Ranch.

Work began in October and will continue this spring on West Creek, and other improvements began two weeks ago on Fox Creek. Both, located along the North Fork near Glen Haven, are being built in partnership with Larimer County, NRCS and the Colorado Water Conservation Board.

Also, Larimer County, private property owners, Colorado Parks and Wildlife and Colorado Department of Transportation officials are working on separate stretches of the river, with everyone working together for overall river benefit.

“We’re making sure our projects are complementing each other to make for an overall healthy watershed,” Jones said.

She expects the work to continue over the next three years as the Colorado Department of Transportation completes the permanent repairs of U.S. 34, which also include massive river restoration work.
