Hi, I’m Holly Strand from the Utah Division of Emergency Management.

The roar you hear in the background is Ashley Creek flowing underneath Highway 191 in Vernal. Rivers and creeks all over the state have been running high with melted snow from the biggest snowpack ever recorded in Utah.

1983 was last time we had anything near this amount of snowmelt fueling our spring runoff. That year, there were multiple 100-year (and bigger) floods. The landslide in Thistle triggered Utah’s first presidential disaster declaration. For weeks, floods, landslides, and debris flows damaged homes, highways, and drainage canals. 22 of Utah’s 29 counties were affected.

This year—with a historic snowpack– it seems like we should be experiencing more 100-year floods or even 500-year floods. Even though only 40 years have gone by since 1983. It’s quite possible, because 100-year floods don’t happen just once every 100 years. They are just projected to happen every 100 years on average**

So did this year’s historic snowpack—more than in 1983–cause another round of 100-year floods? Hasn’t so far and doesn’t look like it will. There has been isolated flooding in some areas, and groundwater flooding, but we just aren’t seeing damage on the same scale that we saw 40 years ago. Why not?

For one thing, Utah communities took lots of mitigation measures in the wake of the 1983 floods. New debris basins were built, stormwater systems improved, river and watersheds were restored, and at-risk structures were flood-proofed. Communities also prepared their residents for floods with information and sandbags! But a big reason Utah didn’t suffer from 100-year or floods, is that the 2023 spring was absolutely ideal for moving water safely from the snowy, high elevations to the thirsty reservoirs and lakes below. Since peak snowpack in the beginning of April, there’s been a long gradual warming trend with no big storms. Stream flows have been consistently high for 2 months instead coming down all at once during a sudden long hot spell of 90 plus temperatures. We dodged a bullet this year thanks to mitigation, preparation and Mother Nature!

Thanks to Glen Merrill with the National Weather Service in Salt Lake City and to Tom Wright, hydrological engineer at AECOM for their expert knowledge.

**A 100-year flood–has a 1% chance of happening each and every year on any given stream reach. Consider what happens when you roll dice. Let’s say you roll a double six. You could get double sixes on the very next roll.  But over many, many, many rolls, you will average double sixes only once every 36 rolls. Similarly you could get a 100-year flood one year, and then the very next year you could roll another 100-year flood but there’s a 99% chance that you won’t. But averaged over a long time, like 1000s of years, a 100-year flood should happen—on average—once every 100 years. To make this concept clearer flood experts prefer to say 1% annual chance flood instead of 100-year flood.

My name is Joey Kozlowski and I live in frosty Logan, UT. For me, most winter days are relatively mundane. The waking hours, which lay only between rising from bed in winter darkness and returning from work in the same darkness, could be described as routine, rhythmic, and rehearsed. During this time of year, it is easy for me to forget the many phenomena around me that make this place I live so unbelievably special. However, certain spontaneous occasions precipitate pause, and make me reflect and appreciate this beautiful and wild place I call home. Recently, I experienced just one of those occasions.

A few weekends ago, my wife’s family came to visit. Her sister (Charri) and sister’s friend (Juan Luis) call the central city of Celaya, Mexico, home. It was Charri’s second time to Utah, and Juan Luis’ first time to Utah, and in fact, it would be his first time ever experiencing snow. The thrill and charm of the natural beauty around them was apparent as they first got out of the car in our driveway. The piles of snow along the sidewalk and the frozen white yard seemed like novel wonders to them both. One of the first things Juan Luis said, that brought me a childish smile was “I’ve always wanted to try shoveling snow,” which I thought to myself go right ahead, here’s the shovel!

Our first outing was a cross country ski/snowshoe trip up Green Canyon. Charri used my MSR snowshoes and Juan Luis fit into my old Fischer XC skis, which no longer had real poles but two wooden sticks to be used as supporting tools. With two black floppy ears bouncing around our legs, the three of us headed off up the trail. It was hard to get 50 feet without them stopping and just taking in the surrounding snow-covered cliffs, picking up fluffy white powder from the side of the trail, or even, in the case of Juan Luis, trying to capture a slow mo video of himself jumping from the trail into the deeper snow. To them, the beauty was so apparent.

The next day, I returned from Edith Bowen Laboratory School where I work, to my home on what is locally known as “The Island,” only to be surprised by a large and perfectly formed snowman in my yard, fully formed with a carrot nose and Oreo eyes. It turns out that Charri, taken back to the excited youthfulness of a child, had spent hours that day just playing outside in the snow and building the snow creature, of which, would quickly lose its eyes and nose to a happy and hungry black lab once we went back inside.

That night, we all received another gift from the great outdoors, at least 12 inches of fresh snow. Juan Luis and I got up early and started shoveling. I’d never seen such an enthusiastic shoveler! It was as if each shovel scoop was filled with ice cream, not snow! He didn’t even seem annoyed when his shovel got snagged on the pesky concrete cracks that seem the bane of my existence! Then, for the climax of their trip, we decided to go to our local ski resort, Beaver Mountain. It was the day any skier dreams of, lots of fresh powder! The awe and excitement in their eyes was present from the moment we started driving up the canyon until the moment their heads started gently nodding off on the tired ride back home. I can’t describe all the beautiful moments of the ski trip, but I can say they truly appreciated each moment for what it was, wild and beautiful, as they struggled to board the magic carpet, laughed as they fell over and over and over again, and nearly burst at the seams with joy when they were finally able to go up the Little Beaver lift and get all the way down on a green trail. In the end, to say these guests appreciated the beauty and excitement of everything a Utah winter has to offer would be an understatement.

So it was, on this occasion with my international family come to visit, that I was reminded of the natural beauty and wonder in all the little things that surround me each day, and that I too often take for granted. I am Joey Kozlowski, and I am Wild about the Winter Wonders of Utah.

Sliding on Ice can be Fun

When cold weather sets into Cache Valley, I usually begin to grumble. But this year, when the weather warmed up and the snow turned to rain, my grumbling got a lot louder.

Everywhere I looked, the sidewalks and roads were covered in ice. I announced that falling on ice was my least favorite activity. I hated ice.

Then I got an unusual Christmas letter from an old family friend, Paulette Campbell. This letter told the story about the skating pond her 3 sons had built for 15 years at their Logan home. The yard was 30 ft wide, 60 ft long, and flat as a pancake – perfect for creating an ice rink. But it took a lot of work. The boys would begin by packing the snow with a heavy roller pulled by their garden tractor. Then they got out the garden hose and sprayed the surface. Three hours later the water had frozen and it was time to spray again. For the next five nights the family pitched in and the ice got sprayed every three hours. The boys packed down the lumpy spots with a shovel.

When the pond was ready, the neighborhood kids flocked to the pond to skate after school. But at 8pm, the floodlights came on and the big kids took over the ice. It was time to play hockey. The boys’ grandparents, who lived next door, pulled their chairs up to the bay window and watched. They insisted on paying the water bill. They insisted the entertainment was worth it.

By the time I finished reading the letter, I had to admit sliding on the ice could be fun.

I was also starting to rerun in my mind my own family ice story. My cousin, Jill Bakken, had been recruited out of high school by the US Olympic committee to give bobsledding a try. Jill took a liking for this slippery sport. In 2002, at the Salt Lake Winter Olympics, Jill and Vonetta Flowers brought home the gold medal in the first ever women’s bobsled event.

Now, twenty years later, and to top off this story, I screwed up my courage and signed up to ride down the Olympic bobsled track. I was tucked in right behind the driver as the 4-man sled roared down the track. We hit 70 mph and pulled about 3 g’s. At the bottom, I got out of the sled a bit shakily.

But now I had a new point of view: Sliding on ice can be exhilarating.

Snow. Tiny specks of dust and other particles in the air that attract water vapor to become ice crystals. That is what fascinated a man named Wilson ‘Snowflake’ Bentley enough to capture thousands of one-of-a-kind snowflake photographs and what drew my friend Alf to Utah. In the winter and early spring of 1989, I sat as a Bonneville Junior High ninth grader with Alf Engen in his office at Alta. As a presenter at the Utah History Fair that year, I was gathering stories and artifacts for my project titled Utah’s Winter King: A Key Individual in the History of Utah’s Ski Industry.

Engen shared stories about building ski jumps over the fences between his home and school and his journey from Norway to America, not to ski but to buy back the Engen estate divided up at his father’s death of the Spanish Flu in 1919. He said, “I was going to make enough money to go back, but I didn’t know how I was going to do that. I didn’t even know there was much snow here, I never read about that.” After sharing stories about arriving in Ellis Island, playing soccer in Milwaukee, scaffold hill jumping on Ecker Hill, and cross-country skiing as a forest service employee over Catherine Pass to imagine Alta as a ski hub, he ended with how he felt about jumping Utah’s snow: “They would say “Send Gummer–that is ‘old man’ in Norwegian–over first,” and I would have to do anything new. I knew I could do it, even if I had never tried it before. Once you are up there, you can fly.”

I had forgotten about that experience chatting about snow with a Utah snow giant until a few weeks ago, gazing out at the snow-frosted hoodoos of Bryce Canyon. I gripe about snow plowing piles and delayed-start school days, and I’d rather cut snowflakes from paper than be out in it most frigid days. Yet, this Christmas a friend gave me a blue and white book titled “The Little Book of Snow.”

For someone who grew up in “the greatest snow on earth,” I thought I knew snow well enough, but in addition to discovering linguistic similarities for the word snow and that some have estimated the number of snowflakes that fall to earth each year to be a number with at least 24 zeroes, I confirmed my suspicions about snow that is not white. I’ve often encountered pink snow patches at the high altitudes of Utah, and with a nudge from the watermelon snow paragraph, I found an intriguing citizen science opportunity online called The Living Snow Project led by Dr. Robin Kodner at Western Washington University. By contributing data about spring snow algal blooms through sample vials or at least observation photographs, scientists can study microscopic snow communities and their impact on snow melt.

Snow. When I asked him what about Utah made him stay, Alf Engen said, “Why, it was definitely the snow.” Snow is the stuff of which stories, science, and wonderful dreams are made.

I’m Shannon Rhodes, and I’m wild about Utah.
