Colorado communities worried about glacier water supplies — The Pueblo Chieftain

From the Associated Press via The Pueblo Chieftain:

Colorado communities that rely on water from dozens of glaciers and glacier features in Rocky Mountain National Park are concerned because the glaciers are shrinking as temperatures climb and winter snowfall becomes more uncertain.

Water from the Poudre, Colorado and Big Thompson rivers get meltwater from dozens of glaciers and glacier-like features around the park.

Park glaciers always vary in size depending on the seasons, but low snowfall amounts could keep them from being replenished. A change of a few degrees when temperatures are near the freezing point can turn snow into rain.

Between the 1990s and 2005, the glaciers started to shrink at an increasing rate. Rocky Mountain National Park’s glaciers were already small by comparison.

The biggest glacier in Rocky Mountain National Park is about 31 acres (13 hectares), according to a study in 2007.

A two-year study is underway to find out how the glaciers have changed in area and volume since 2005. Scientists will be using historic maps, climate records, photographs and measurements to better understand what’s happening.

Scientists will also study how glacier melt influences rivers, by measuring streamflow and collecting water samples to see how much water glaciers contribute to rivers…

Even a small loss in the snow and ice that feed rivers in northern Colorado could have a big effect on water supplies to Fort Collins and other nearby communities.

Paul McLaughlin, an ecologist at the park’s Continental Divide Research Learning Center, said changes in the amount of water and temperatures could also damage delicate river ecosystems.

Teens help with river restoration project as part of North Fork flood recovery By Pamela Johnson — the Loveland Reporter-Herald

From The Loveland Reporter-Herald (Pamela Johnson):

The project, spearheaded by Wildlands Restoration Volunteers, is wrapping up, and a crew of teens attending a fly-fishing camp this week planted trees, shrubs and grass on a section of the river about 2 miles above Drake as part of the final touches…

The Big Thompson River and the North Fork suffered severe damage during the September 2013 flood. Torrents of water wiped out homes, sheds, trees, boulders and anything else in their path and left behind destruction that, in many places, resembled a barren moonscape…

During the aftermath of the flood, Wildland Restoration Volunteers began reaching out to find ways to help restore trails, wildlands and sections of the river.

They connected with Chenoweth and other landowners and applied for state grants to redesign and rehabilitate a 2.5-mile section of the North Fork to be studied and used as an example for future projects. Most of the land in the project is owned by the Chenoweth family and Colorado Parks and Wildlife.

With $360,000 in grants and $140,000 worth of donated time and supplies, crews and volunteers have realigned and regraded the river channel to make the river and surrounding habitat healthy and more able to survive a future flood.

This included specifically designing the depth of pools in the river, carefully placing rocks to create ripples in the water and to stabilize the bank and creating areas along the river that will allow water to slow down and spread out in the event of another flood.

The next step was to plant vegetation along the river to enhance habitat and to protect the banks from erosion.

The teens from the Rocky Mountain Flycasters Fly Fishing Conservation Camp worked on the planting this week, putting in willows, cottonwoods, dogwoods, chokecherry trees and native grasses.

Luke McNally, who works for Wildland Restoration Volunteers, pointed out to the teens the trees that survived the flood as well as grasses that have returned since. But, he noted, the amount of plant life is nothing compared with what was there before the flood…

The goal of the camp, which is in its seventh year, is for the teens to learn about fishing as well as ecology and conservation and to stir in them a love of the outdoors and a desire to protect the lands, noted Dennis Cook, camp director and a member of Rocky Mountain Flycasters.

Larimer pays $8.4 million for farm, water rights — Loveland Reporter-Herald

Here’s the release from Larimer County (Kerri Rollins):

Larimer County Department of Natural Resources purchased a 211-acre farm southwest of Berthoud, along with its valuable water rights. The deal closed Monday, August 8.

Using Help Preserve Open Spaces sales and use tax dollars, Larimer County Department of Natural Resources purchased the property, known previously as the Malchow Farm, to conserve its agricultural, historic, scenic, community buffer and educational values. General public access is not permitted at this time. Larimer County plans to continue leasing the property as an active agricultural farming operation.

The Town of Berthoud provided $100,000 to Larimer County to help purchase the farm, which will also help leverage a potential Great Outdoors Colorado funding request being submitted later this month.

“We’re excited to acquire this farm and its myriad of conservation values,” said Gary Buffington, director of Larimer County Department of Natural Resources. “The property helps us further our mission to conserve working lands and foster an appreciation for our agricultural heritage in Larimer County.”

This property is located one mile southwest of Berthoud, just north of the Little Thompson River and adjacent to U.S. 287 on the highway’s west side. It consists of high-quality agricultural soils, with approximately 188 irrigated, 18 pasture and 5 farmstead acres. Located just north of the Larimer-Boulder county line, the property serves as a gateway to Larimer County and a doorstep to the town of Berthoud, with sweeping views of Longs Peak and the Front Range. The property contains several historic features, including a pioneer gravesite, beet shack and a big red barn that can be seen for miles. The Overland Trail once crossed the property.

The property, infrastructure and minerals were purchased along with the valuable water rights, including 240 units of Colorado-Big Thompson, or C-BT, water, 16 shares of Handy Ditch native water rights and 20 shares in Dry Creek Lateral Ditch.

Larimer County is actively seeking partners to engage in a water sharing agreement on this property that will provide partnership funds toward the purchase of the water, keep the farm in active production and allow water partners to share some of the water in drought years. This water sharing agreement, known as an Alternative Transfer Mechanism, or ATM, is a cooperative solution encouraged by the Colorado Water Plan to share water across uses without permanently drying up high-quality working farms, such as this farm near Berthoud.

Larimer County has developed a stewardship plan for the property and will develop a full management plan with public input within the next several years. The property was purchased from the Malchow family, but an official name for the property, now that it’s a Larimer County open space, will be chosen at a later date. Public tours of the property are planned for later this year.

For additional information, contact Kerri Rollins, Open Lands Program manager, at (970) 619-4577.

From The Loveland Reporter-Herald (Pamela Johnson):

Larimer County now officially owns the 211-acre Malchow farm south of Berthoud and its associated water rights — a unique agreement that includes a water sharing component.

The $8.4 million sale from the Malchow family to the Department of Natural Resources closed Monday.

The county bought the property to conserve its agricultural, historic and scenic values and plans to continue leasing the fields as an active farm.

One unique aspect of the sale was that the county also bought the water rights, including 240 units of Colorado-Big Thompson water, with the intention of entering into a water sharing agreement.

Under such an agreement, the farm may vary its crops over several years, so in drought years, some of the irrigation water can be sold.

This allows the farm to stay in production for the long-term and is an arrangement encouraged by the Colorado Water Plan.

The farm is located along U.S. 287 one mile southwest of Berthoud, and along with rich farmland, it includes historic buildings and a pioneer grave site believed to be tied to the Overland Trail, which once crossed the property…

The farm will not immediately be open for public access. However, a management plan that will be developed within the next few years could include an educational component in which the farm may be used to teach the public about agriculture.

The town of Berthoud pitched in $100,000 toward the purchase of the property, and Larimer County will be applying for a Great Outdoors Colorado grant to help with the cost.

Broomfield purchases 120 shares of water for $3.24 million — The Broomfield Enterprise

From The Broomfield enterprise (Danika Worthington):

The auction room was packed with bidders, but only 13 — including the City and County of Broomfield — emerged from the Larimer County Fairgrounds with a piece of the Reynolds portfolio. Municipalities, developers and farmers all grabbed some units of Colorado-Big Thompson water, while developers and growers signed deals for land.

The auction was of high interest, given the land’s location in the path of northern Front Range development and the large amount of water attached to it.

Although the numbers are still preliminary, Hall and Hall Auctions partner Scott Shuman said 276 CB-T units brought in the largest chunk of money, about $7.6 million or an average of $27,356 each. The CB-T units, already trading for high sums, were expected to be the most pricey given their scarcity and the ability to use the water for uses such as agriculture, development and industrial processes, including oil and gas extraction.

According to Pat Soderberg, finance director for Broomfield, the city and county placed a bid for 120 shares at $26,000 per share, plus a 4 percent processing fee.

That puts Broomfield’s purchase at $3.24 million, with a 10 percent down-payment of $324,480. The balance will be paid at closing, Soderberg said.

But on a per-share basis, the 15.75 Highland Ditch shares stole the show, averaging $148,900 each for an estimated total of $2.3 million. All the shares were sold to farmers or investors.

Although CB-T water got most of the attention prior to the auction, Shuman said the ditch shares provide more acre-feet of water than CB-T and are not limited to a specific geography. CB-T water, which is conveyed from the headwaters of the Colorado River near Grand Lake, can be used only within the boundaries of the Northern Colorado Water Conservancy District.

July 31, 1976, Steamboat Springs: I had been wandering around the Flat Tops Wilderness for a week or so with Mrs. Gulch. Drizzle in between downpours during the monsoon. We were holed-up in a hotel to dry out and I phoned my mother to check in.

She asked, “Johnny are you anywhere near the Big Thompson Canyon? There’s been a terrible flood.”

And it was a terrible flood. After the September 2013 floods Allen Best wrote about being part of the disaster response in The Denver Post. It’s a good read on this 40th anniversary. Here’s one passage:

I was at the Big Thompson disaster. I was living in Fort Collins then and was among scores of young men (sorry, women, those were different times) with strong backs who could be summoned in case of forest fires. My only fire was at an old sawmill site in the foothills. The joke was that one of us had set the fire because we were so desperate for minimum-wage work.

Then came July 31. It was hot that night in Fort Collins. It hadn’t rained a drop.

I was living above Gene’s Tavern, just two blocks from the Larimer County Courthouse. When the call came, I was at the sheriff’s office almost immediately. It was 9 p.m.

Being among the first at the command center at the Dam Store west of Loveland, near the mouth of Big Thompson Canyon, I was assigned to a pickup dispatched to look for people in the water near the turnoff to Masonville. Already, the river was out of its banks. From the darkness emerged a figure, dripping and confused. “I went fishing at Horsetooth (Reservoir) and was driving home and then there was all this water,” he sputtered. He was befuddled. So were we.

Our leader decided we’d best get out of there. From what I saw the next morning, that was an excellent decision. Water later covered the road there, too. I spent the night at the Dam Store as the water rose. Helicopters were dispatched, but there was little that could be done. Our lights revealed picnic baskets, beach balls and propane bottles bobbing in the dark, roiling water that raced past us, but never any hands summoning help.

Here’s an excerpt from a look back forty years from Michelle Vendegna writing for the Longmont Times-Call.

Night on the ledge

“We, Terry Belair-Hassig and Connie Granath-Hays, graduated from Berthoud Jr. Sr. High School the month before, and were anxious to begin the summer. We spent the beautiful, sunny day of July 31, 1976, at a Hewlett-Packard company picnic at Hermit Park not far from Estes Park. After the picnic, we drove up to Estes Park and had dinner at Bob and Tony’s Pizza.

The clouds started moving in about 6 p.m., so we began the drive down to Loveland via U.S. 34. Within minutes, Connie had to pull her car over because the driving rain was causing zero visibility. We needed to get home, so she started out again, but we didn’t get too much farther before we were blocked by trees, boulders and debris washing down the canyon sides. We had just passed the Loveland Heights area — barely three miles since entering the canyon. The closest town, Drake, was miles away.

Connie pulled over to the side of the mountain as far as she could. There were a few other cars in this section doing the same, but we all sat in our cars — planning to wait out the storm. However, once the river began to rise and the water was hitting the tires, we decided to leave the car and start climbing. Connie’s dad had taught her to always ‘be prepared,’ so she had a tarp and a few extra jackets stored in her trunk. We grabbed them before climbing. It was a dark, treacherous climb.

A small group of people scrambled up the mountain near us. Connie gave one of the men her extra jacket. She also had a flashlight which came in handy later in the evening when the lightning wasn’t lighting up the canyon. The other people were lucky enough to find an overhang of rocks to sit under. We tentatively settled on a ledge out in the open, and wrapped ourselves in the tarp. Of course, the tarp was just an old tarp, not waterproof like the ones are today. It protected us for a while, but with the downpour of rain and runoff from the hillside, it too became drenched.

After only a little while, we watched her car, during the lightning flashes, being lifted up and carried down the river. We decided at this point we should climb higher, so we found a ledge where we spent the long, cold night. We had spent many winters skiing and had never been as cold as we were that night.

We sat on that little ledge (3 foot by 1 foot) with our knees drawn up to keep us from sliding off. We sang, shivered, cussed and did anything we could to keep our minds off of how cold and achy we were. We heard and saw cars, houses and propane tanks floating down the river during flashes of lightning. We thought by now it must be about morning time, but looking at our watch, it was about 10 p.m. We had a long night ahead of us.

The next morning was another blue bird day and we were freezing and soaked to the bone. We decided it would be warmer to take our jackets off and left them on the ledge. The road below us had been washed away, but the river had receded enough that we could get off the ledge and move around a little on the steep mountainside. We heard the helicopters for a long time before we saw one. Finally, we were rescued off the side of the mountain by a four-seat helicopter,and dropped off up river on a section of the highway that had survived. There were several other people there. I remember we were all surveying the canyon in a daze. There wasn’t much conversation. I leaned over and picked up a small piece of asphalt and put it in my pocket.

From Wikipedia:

On July 31, 1976, during the celebration of Colorado’s centennial, the Big Thompson Canyon was the site of a devastating flash flood that swept down the steep and narrow canyon, claiming the lives of 143 people, 5 of whom were never found. This flood was triggered by a nearly stationary thunderstorm near the upper section of the canyon that dumped 300 millimeters (12 inches) of rain in less than 4 hours (more than 3/4 of the average annual rainfall for the area). Little rain fell over the lower section of the canyon, where many of the victims were.

Around 9 p.m., a wall of water more than 6 meters (20 ft) high raced down the canyon at about 6 m/s (14 mph), destroying 400 cars, 418 houses and 52 businesses and washing out most of U.S. Route 34. This flood was more than 4 times as strong as any in the 112-year record available in 1976, with a discharge of 1,000 cubic meters per second (35,000 ft³/s).

From The Greeley Tribune (Tyler Silvy):

Officials on Friday detailed how a Big Thompson River that was flowing at 30 cubic feet per second increased to 30,000 by the time it got to the narrows near Sylvan Ranch and the Dam Store.

The 2013 flood, by contrast was flowing at 16,000 cubic feet per second at the same point. But Bob Kimbrough, from the U.S. Geological Survey, said that number can be misleading. Just because it was flowing at less than half the rate, doesn’t mean the water was half as high as it was in 1976. It could have been a foot or two lower, Kimbrough said.

Further, the 2013 flood lasted longer. Where the 1976 flood dissipated nearly as quickly as it rose, the 2013 flood flowed over saturated ground for days, causing foundation failures and greater erosion than the 1976 flood.

1976 Big Thompson Flood

Jason Pohl hits a home run with his 40th anniversary story about the July 31, 2016 Big Thompson Flood. Click through and read the whole article. Here’s an excerpt:

But Jerry Shaffer has learned to close his eyes and breathe deeply when memories surface of flailing through the milky, murky torrent of the Big Thompson Canyon. He can’t shake the mental scars of dodging missiles disguised as spewing propane tanks, crunched homes, and the bodies lifeless men, women, and children that overtook a popular tourist route to Estes Park the night of July 31, 1976.

And he’ll never forget holding a loved one’s body in his arms before the water whooshed him away, too.

All told, Colorado’s deadliest natural disaster claimed 144 lives, injured scores of others, and permanently altered memories and landscapes alike. It prompted new talks about living in flood country and became the “where were you” moment for a generation, ranking alongside Dec. 7, 1941, and Sept. 11, 2001.

It started about 9 p.m. Saturday night, on the eve of Colorado’s 100th birthday.
