SECTIONS COVER ART Foggy morning in Thompson Falls

By Andy Welch, NorthWestern Energy Manager of Hydro License Compliance “This photo was captured on a cold, foggy morning in Thompson Falls, just as the sun was rising above the horizon and peeking through the clouds. Foggy mornings at our hydro facilities are magical and conjure warm feelings of isolation and calmness while doing our work. I’m lucky that I get to spend a lot of time at our hydro facilities, which are some of the most beautiful places in the state.”

THE BRIGHT SIDE / at the end of the year as NorthWestern’s Director of Environmental & Lands Permitting & Compliance, I was involved with hundreds of power projects that affected the land, water, air and wildlife. In every case, my goal was to try to find a balance between the need to provide energy and protect the environment. I am proud of the times we were able to do this, from changing the location of a power line to avoid an important cultural site to installing secondary containment to ensure oil in the substations didn’t leak. From permitting gas compressor stations responsibly to recycling thousands of street lights being replaced with more efficient ones.

There were much bigger projects, too. Our bird biologists led the electric utility industry in preventing eagles from being electrocuted by writing new design standards for power poles. Together, our team developed recreation sites up and down the Missouri and Madison rivers, financed by a trust fund established when the dams were relicensed. We reclaimed critical wetlands along O’Dell and Moore creeks, and operate the fish ladder at Thompson Falls to enable tens of thousands of fish to complete their migration to spawn.

Those team efforts are among the high points of my career. But when I think back on what I am most proud of, it was to work alongside the smart, commitDear Readers,

“This feels pretty incredible,” Bob said.

The Names on the Dams Of NorthWestern Energy’s 11 hydro facilities, seven are named for pioneering leaders who helped shape Montana’s energy future.

Cochrane Dam – Named for Harry H. Cochrane, who helped design dams and transmission lines and became Montana Power Co.’s chief engineer when the company was formed in 1912. He held that position until 1949, when he became a consulting engineer for the company, a post he maintained until his retirement in 1962.

Hauser Dam – Named for Samuel T. Hauser, an entrepreneur and governor of the Montana Territory from 1885 to 1887.

Hauser was involved in an array of business ventures ranging from ranching and mining to railroads and banks. Hauser was a key promoter and minor investor in the first Canyon Ferry Dam, led the construction of his namesake dam north of Helena and had plans for another project downstream near Wolf Creek.

Hebgen Dam – Named for Max Hebgen, who around the age of 20 began working as a lineman in Butte, Montana, and went on to become nationally known in the growing field of electricity development. Hebgen played a large role in the development of several hydroelectric dams and saw the potential of using electricity to serve Montana’s cities and towns.

Holter Dam – Named for Anton Holter, known as the “father of the lumber business in Montana,” with lumberyards in Virginia City, Nevada City, Helena, Great Falls, Sun River and Fort Benton. He founded the A.M. Holter Hardware Company and became involved in a variety of mining, agricultural and real estate ventures.

Morony Dam – Named for John Morony, a leader of the Great Falls Water Power and Townsite Company and a key advocate for the purchase of the nearby Missouri River dam sites.

Later, he went on to be one of the first directors of the Montana Power Co. Rowe Dam – Named for Bob Rowe, who served as CEO for NorthWestern Energy from 2008-2022. During his tenure, Bob led the acquisition of 11 hydro facilities from PPL Montana for $870 million. Prior to working at NorthWestern Energy, Bob served on the Montana Public Service Commission from 1993-2004.

Ryan Dam – Named for John D. Ryan, who played a large role in developing what would become the Montana Power Co. hydroelectric system. Starting before Montana Power Co. was formed in 1912, Ryan, who also led the Amalgamated Copper Co. (and later the Anaconda Company), first saw the value of electricity to mining and smelting operations. Later, he embraced the broader financial value of electric production.

IT’S ELECTRIC

By Erin Madison

Mystic Hydroelectric crew converts an old diesel train to electric.

Reaching Rowe Dam at Mystic Lake is no small task for our crews who work at the remote hydroelectric facility.

The Mystic Hydro Plant is nestled below the rugged snow-capped peaks of the Beartooth Mountains, 75 miles southwest of Billings, Montana. The powerhouse sits at the valley floor, while Rowe Dam is perched on a mountain side, 1,130 feet above the powerhouse.

to run on electricity.

It’s hard to reach the upper train, but it was even harder to get the train down to the powerhouse where the crew could work on it.

“We had to helicopter it out,” Joe said.

Since there’s not a premade electric conversion kit to turn an old diesel mining train into an electric train, Joe and the crew had to get

there, they get on another train that takes them the rest of the way to Rowe Dam. The second train was originally installed in 1978 or ’79 and was an old mining locomotive that ran on diesel fuel.

“It was noisy, smelly and hard to start,” said Joe Ruprecht, Journeyman Maintenance Operator at Mystic.

This past winter, the Mystic hydro crew converted the diesel train

18 | BRIGHT MAGAZINE Vol. 3

“We all brainstormed on how to put it together,” Joe said.

The train now has an onboard generator to charge the motor.

They also installed a solar charging system. Joe estimates they can run the train for about a week without needing to charge it.

The retrofitted train is about 25 to 30 decibels quieter than it used to be, plus it’s easier to start and can haul more passengers and cargo.

“It makes it way more convenient to get up to the dam,” Joe said.

Our Mystic hydro crews recently converted one of the trains used to reach Rowe Dam at Mystic Lake to run on electricity.

caused by tree-related incidents.

“We’re mainly trimming to help prevent trees from growing into power lines and identifying trees or parts of trees that could potentially fall onto the lines,” Zach said.

Despite occasional tree-related outages due to weather, Zach’s proactive approach helps identify potential risks beforehand, reducing the likelihood of outages caused by trees.

“We’ve established a cycle for our vegetation management system.

We start with a substation and work through all the circuits connected to it to ensure nothing is missed,” he said.

By prioritizing one substation at a time and trimming all the circuits connected to it, Zach’s team ensures that every inch of a region becomes more dependable and resilient in the face of unforeseen events.

Environmental concerns play a significant role in vegetation management. The team schedules trimming activities at appropriate times.

“We’re not going to go in there and disturb someone’s property, whether it be a farm field, their lawn, or just a regular field. We’re going to wait until the ground’s solid,” Zach said.

Zach strives to approach tree trimming as an arborist, prioritizing both the energy system requirements and the visual appeal of the tree.

The future of

BLUE SUCKERS

By Erin Madison

NorthWestern Energy and our partner agencies are studying why juvenile blue suckers seem to be missing from the population.

It’s likely that some of the blue sucker fish found in Montana’s Missouri River could be nearly 70 years old. However, young blue suckers seem to be missing.

“In the last 23 years, we have not observed any young blue suckers,” said Grant Grisak, Biologist with NorthWestern Energy.

Blue suckers are considered a species of special concern in Mon-

netting, seining and trawling. We’ve also surgically implanted radio transmitters in adult fish to follow their movements throughout the year.

“We look at their behavior and try to make some determinations about what those fish are responding to during the winter time, during the summer or during their spawning season,” Grant said. “We’re building a picture of what their behavior is like.”

Thompson Falls

For

NEW FLASHBOARDS WILL ALLOW THOMPSON FALLS DAM TO OPERATE MORE EFFICIENTLY

In order to replace the flashboards at Thompson Falls Dam, we had to lower the reservoir elevation by about 16 feet.

26 | BRIGHT MAGAZINE Vol. 3

Until recently, the water in the Thompson Falls Reservoir was held back by boards that were about a half-century old. Overtime, those boards became worn from the water.

“The wooden flashboards on the main dam had been in place for about 50 years,” said NorthWestern Energy Hydro Foreman Noel Jacobson. “The boards were leaking water, which requires a high level of maintenance and frequent repairs.”

In October, our crew at Thompson Falls removed the flashboards and replaced them with all new boards. The project was no small task. There are about 175 boards along the face of the main dam, all 24 feet in length.

Many of the boards our crew removed had small holes in them. Others were worn in the spots where they sit against the steel I-beams of the dam.

Those small leaks can add up to a lot of lost energy generation. A 250-cfs (cubic feet per second) water leak through the dam, about 1,870 gallons per second, equals almost a megawatt of power, enough energy for about 650 homes a year.

In order to replace the boards, we had to lower the reservoir elevation by about 16 feet.

“In my 25 years here, I’ve never seen the reservoir this low,” Noel said.

The low water did uncover some rarely seen artifacts in Thompson Falls Reservoir. The most noticeable was an old set of train tracks dating back to 1915 that were used when the dam was under construction. The tracks run along the bank before falling off into what is now the reservoir. There are also two piers that can be seen rising above the low water. Those piers allowed the tracks to reach the dam.

“It’s surprising they didn’t at least remove the tracks,” Noel said.

Instead, when construction of the dam was finished in 1916, the tracks were flooded by the newly formed reservoir and are still there today.

Crews also found some other items in the river, such as chains, pipes and an old rock foundation.

While the reservoir was drained, NorthWestern Energy conducted a LiDAR flight. LiDAR, which stands for Light Detection and Ranging, will allow us to create a detailed map of the bottom of the reservoir.

“The LiDAR provides a high-resolution snapshot of the entire reservoir shoreline and exposed reservoir bed paired with aerial photography,” said Andy Welch, Manager of Hydro License Compliance at NorthWestern. “This data will enable NorthWestern to evaluate such things as habitat complexity, location of shoreline infrastructure, bank stability, and reservoir bed slope and provides something to compare changes to those characteristics with in the future.”

Once the boards were all replaced, Thompson Falls reservoir returned to its normal level. The new boards will likely be in place for another 50 years.

“Replacing the boards will reduce maintenance and make the dam perform more efficiently,” Noel said.

 Top: Crews remove old flashboards at Thompson Falls Dam. Middle: The old flashboards at Thompson Falls Dam had become worn and cracked after about 50 years of use.

Saving the Big Sky

By Erin Madison and Bruce Bugbee

Book chronicles the history of private land conservation in Montana and the impact it’s had on the state.

The Rattlesnake National Recreation Area and Wilderness is part of what makes Missoula special.

However, its creation was far from certain.

Back in the 1970s, Bruce Bugbee explored the watershed with other University of Montana graduate students, wondering how this amazing resource could be conserved. In the early 1980s, Bruce was hired by the Montana Power Company (now NorthWestern Energy) to negotiate the sale of 21,000 acres of corporate land in the Rattlesnake to the U.S. Forest Service. The City of Missoula, Friends of the Rattlesnake and Congressman Pat Williams were strongly on board.

In 1980, the Rattlesnake National Recreation Area and Wilderness was established by Congress. It would never have happened without the company’s commitment to the people of Montana and the state’s natural environment.

It was Bruce’s experience in the Rattlesnake that inspired his career in land conservation and now his book on the history of private land conservation in Montana. Bruce is the co-author of the upcoming book, “Saving the Big Sky: A Chronicle of Land Conservation in Montana.” The book looks at the 6 million acres that have been voluntarily

28 | BRIGHT MAGAZINE Vol. 3

protected in Montana over the past 50 years and includes information on the role of NorthWestern Energy played in that conservation.

“They deserve to be recognized and thanked,” Bruce said.

The Alberton Gorge is a whitewater rafting treasure on the Clark Fork River. Years ago, the Montana Power Company owned the right to develop a dam site at the lower end of the gorge and flood adjacent lands. Bruce, on behalf of the Montana Power Company, worked with Five Valleys Land Trust to craft a land exchange project that protects riverside lands from development and keeps a dam from being built.

The company worked with Bruce in a similar way to conserve Mesa Falls on the Snake River in Idaho.

Power generation is NorthWestern Energy’s core mission, but its projects can affect the people and landscapes of Montana.

When operations at Kerr Dam, now Selis Ksanka Qlispe Dam,

The Alberton Gorge on the Clark Fork River

impacted shoreline ecosystems around Flathead Lake, the Montana Power Company, which then owned the dam, purchased land to create Lost Trail National Wildlife Refuge west of Kalispell. This is called “off-site mitigation,” making up for habitat losses in one place by protecting similar habitats elsewhere.

In 1997, the Missouri-Madison River Fund was established to mitigate the effects of the company’s Madison and Missouri river dams.

“Saving the Big Sky: A Chronicle of Land Conservation in Montana,” by Bruce Bugbee, Robert Kiesling and John Wright.

The book will be published

by Oregon State University Press in the spring of 2025.

Nearly $20 million in NorthWestern Energy and public sector funds have been leveraged to improve the quality of public recreation access along these prized waterways.

“The Missouri-Madison River Fund has been a huge factor in land conservation and public access,” Bruce said.

“This collaborative process has been highly successful.”

When Bruce reflects on his 50-year career in land conservation, he sees relationships, finance and reciprocity as key ingredients.

“When we treat each other with respect, the public and the land benefit in the long run,” Bruce said.  Bruce Bugbee holds a draft copy of his book “Saving the Big Sky: A Chronicle of Land Conservation in Montana.”

CAPTURING A

LEG Photos for the Library of Congress’ Historic American Engineering Record document engineering and infrastructure for future generations.

By Erin Madison

A few hundred years from now, people may want to look back and see how a 1900s powerhouse worked or how a bridge was constructed at the turn of the century. For this reason, the Library of Congress keeps a photo collection called the Historic American Engineering Record.

“They want a historic record of our engineering accomplishments,” explained Photographer Kristi Hager. “Otherwise, there’s very little recorded.”

Many of NorthWestern Energy’s dams are listed on the National Historic Register, so when we do maintenance or upgrades, we often have to photograph our old equipment for the Historic American Engineering Record.

For about 25 years, Kristi was NorthWestern Energy’s primary HAER photographer. She subcontracted with a historic preservation firm and photographed nearly all of NorthWestern’s hydro facilities and some other structures. She also worked with the Montana Department of Transportation to photograph bridges and other infrastructure.

Kristi, who retired in 2019, has some 1,200 photos archived in the Library of Congress, but she fell into the line of work somewhat by chance.

“I have a background in photography,” Kristi said. “I’m a painter and photographer, and I used to teach photography.”

When Kristi moved to Montana from California, her studio was located above a historic preservation firm.

“I supported my painting by doing drafting,” said Kristi, who has an undergraduate degree in architecture.

The firm had a large-format camera that she was allowed to borrow to photograph her artwork. When the employee who did historic preservation photography left the firm, they asked her to take it over since she knew how to use the large-format camera.  Before the Rainbow Powerhouse near Great Falls, Montana, was razed, Photographer Kristi Hager captured 140 photos of the powerhouse.

34 | BRIGHT MAGAZINE Vol. 3

Kristi ended up starting her own historic preservation photography business.

ACY

The bulk of her work was with the Montana Department of Transpor-

tation, photographing century-old bridges that needed to be replaced.

She also worked frequently with Montana Power Company and then NorthWestern Energy to capture our hydro facilities.

“These power plants were a major accomplishment in terms of what it brought to the community and engineering-wise,” Kristi said.

Kristi’s largest project was documenting the original Rainbow Powerhouse near Great Falls before it was razed.

“The whole building and everything in it was going to go away,”

 Photographer Kristi Hager uses a large-format camera to capture images for the Historic American Engineering Record.

Kristi said.

Kristi captured the interior of the powerhouse, the exterior and all the equipment.

“Everything that went into making that power plant operational,” she said.

The project, which included 140 photos of the powerhouse, took her two years to complete.

“We came up with a complete list of every photograph that needed to be taken,” she said.

The large-format camera used for historic preservation documentation is not easy to use. It weighs about 30 pounds and shoots sheets of negatives that are 4 inches by 5 inches. Everything about the camera is manual and has to be adjusted by hand. Because it’s so slow to set up the camera, Kristi only took about 10 photos per day.

She spread the Rainbow Powerhouse shoot over two summers, spending a week in Great Falls to gather photos, and then coming back again several weeks later.

“It’s heavy, physical work,” Kristi said.

The Library of Congress requires a minimum negative size of 4 inches by 5 inches.

“The bigger the negative, the finer the detail is of the imagery,” Kristi explained. “The image can be blown up quite large without losing detail.”

The photos have to be captured on black-and-white film.

“The Library of Congress wants something that is stable for 500 years,” Kristi said.

Black-and-white film is the most archivally stable medium, more stable than digital photography.

The photos also can’t be taken in the winter because snow would obscure details and information.

Occasionally, Kristi thinks about what people who are looking at these photos 100 years from now might think.

“These things that are familiar to us will probably look very exotic and from a bygone time that no one ever experienced,” she said. “There is a legacy that you can’t anticipate.”

“For the Record” Exhibition Photos for the Library of Congress’ Historic American Engineering Record are required to show infrastructure clearly so that future generations can understand how it worked and the context in which it existed. However, the photos are also supposed to be as aesthetically beautiful as possible.

“They don’t want you to just take the equivalent of a mug shot,” Kristi said. “They want you to use the lighting and the composition in a way that enhances the beauty of the structure.”

Kristi doesn’t consider her historic preservation photography to necessarily be a work of art, but some of the photographs she took over the years really did rise to the level of art.

The HAER collection is publicly available online but is not often viewed.

“It’s in the public record but it isn’t really seen publicly,” Kristi said.

For that reason, Kristi worked with Brandon Reintjes, Senior Curator at Missoula Art Museum, to organize the exhibition “For the Record: Montana’s Historic Bridges, Powerhouses, And Missile Sites, Inside and Out” with funding from the Foundation for Montana History. The exhibition features 28 of Kristi’s photos and will travel around the state under the auspices of the Montana Art Gallery Directors Association.

BUILDING HABITAT WITH HIGH FLOWS

 NorthWestern Energy and Montana Fish, Wildlife & Parks work together to capture aerial images of the Madison River near Ennis in late May 2023.

36 | BRIGHT MAGAZINE Vol. 3

Our Madison River Flushing Flow Program helps improve spawning habitat for fish.

By Erin Madison At the end of May, flows on the Madison River were higher than normal.

This was due to NorthWestern Energy increasing the volume of water released from Hebgen Dam. When snowpack allows, NorthWestern Energy implements our Madison River Flushing Flow Program. The program is designed to augment natural river flows with surplus water.

The goal of sending the extra water down the river is to flush fine sediments from Madison River gravel to enhance the quality of spawning gravels that support the healthy wild trout fishery.

High spring runoff flows, which the flushing mimic, are a natural occurrence in undammed rivers. These high flows help create spawning habitat for fish by clearing out fine particles from the river bottom where fish spawn. It also helps distribute food for fish and improves the quality of the river’s insect community.

While the water was at its peak, NorthWestern Energy conducted a drone flight to capture aerial footage of the river at high water. This allowed us to see how wide the river channel expanded. When a river channel reaches its floodplain, it has the opportunity to deposit fine sediment onto gravel bars and streambanks, which helps provide fresh soil for new cottonwood and willow seedlings to grow.

The 2023 flushing release from Hebgen Dam is a cooperative effort planned by NorthWestern Energy; Montana Fish, Wildlife & Parks; Montana Department of Environmental Quality; the U.S. Bureau of Land Management; the U.S. Fish and Wildlife Service; and the U.S. Forest Service.

Whisk the cake flour, cocoa powder, baking powder and salt together in a medium bowl. Set aside. Using a mixer, whisk the egg whites and

½ cup sugar together on high speed for 4-5 minutes or until stiff peaks form. Transfer to another bowl. In the same mixing bowl, beat together the egg yolks, remaining sugar, oil and vanilla extract for 3-4 minutes.

YULE LOG CAKE

Originating from Germanic and Scandinavian culture, many parts of the world celebrate Christmas, the winter solstice and other winter holidays by burning a Yule log for good luck and fortune. Stemming from that tradition, the French created a cake called a Buche de Noel, or Yule log. The cake is similar to a Swiss roll – a soft sponge cake rolled up with whipped cream filling and decorated to look like a section of tree. Thompson Falls has deep roots in the timber industry, so a Yule log seems particularly fitting for a winter adventure in northwest Montana.

INGREDIENTS

Fold half of the whipped egg whites into the egg yolk mixture with a spatula. Repeat with remaining egg whites. Fold half of the flour

mixture into the eggs with a spatula until combined. Repeat with remaining flour mixture. Avoid overmixing and deflating the egg whites.

Our Net-Zero Vision Over the past 100 years, NorthWestern Energy has maintained our commitment to provide customers with reliable and affordable electric and natural gas service while also keeping our commitment to environmental sustainability front and center. In early 2022, we took our commitment a step further and announced our plan to reach net-zero emissions by 2050.

As we transition to a net-zero portfolio, we will continue to focus on supplying our customers with reliable energy at the most affordable rates possible.

Over the last 10 years, nearly all the owned electric generation we have put into service in Montana and South Dakota are carbon-free resources. Over time, we expect to close our coal plants at the earlier of depreciable life or when the plant is no longer cost effective. Until longer duration carbon-free resources are available and cost effective, we are likely going to need natural gas-fired generation to supplant the output and capacity provided by our coal resources.

Learn more at NorthWesternEnergy.com/NetZero.

At NorthWestern, we understand that almost everything we do to produce and deliver energy to our customers impacts the environment.

That’s why caring for the environment is one of our SERVICE values.
