Utah Reservoirs Ended the Year at 47 Percent. The Bottom Did Not Get Any Cleaner.
Utah's 2026 water year closed on September 30, and the numbers are hard to read any other way. Statewide reservoir storage started the year at 60 percent of capacity and ended it at 47 percent, according to Utah Division of Water Resources data reported by KSL. The peak, in May, was just 71 percent, 15 points below the year before.
The strange part is that it was not a dry year on paper. Mountain sites collected 28.1 inches of precipitation, about 96 percent of normal. Record warmth did the damage. Snow lines sat at 11,000 feet during storm after storm, so rain fell where snow should have. Most of what did fall as snow melted in March.
A Snowpack That Never Showed Up
Snowpack supplies roughly 95 percent of Utah's water. This year it hit its lowest April 1 point since tracking began in the 1930s, peaking at 8.4 inches of snow water equivalent. Twenty one Utah streams recorded their lowest snowpack runoff on record, and 17 more recorded their second lowest.
"It's unprecedented," Utah Snow Survey director Jordan Clayton told KSL, adding that the reservoirs "didn't fill the way we need them to fill." The Great Salt Lake fell to its second lowest point on record this year.
The outlook is a coin flip. More than 85 percent of the state is still in severe or extreme drought, though mountain soil moisture is above normal heading into winter. Forecasters give a very strong El Nino better than a 90 percent chance, but nobody can yet say what that means for Utah.
Less Water, Same Debris
When a reservoir drops, nothing on the bottom goes anywhere. The cans, tackle, glass and lost gear are still there. There is simply less water above them and less water around them.
That matters for water quality. Utah depends on these reservoirs for drinking water, irrigation and recreation, and every foot of drawdown means whatever is down there is sitting in a smaller volume of water that has to stay clean.
Fathom Restoration is a disabled-veteran-led Utah 501(c)(3) nonprofit, and our volunteer divers work on exactly this problem. We go under the surface of Utah lakes and reservoirs and bring up what has settled where nobody on the bank can see it. On two September crew dives in Rainbow Bay at Deer Creek Reservoir, we brought up about 58 pounds of trash by our estimate, including paddles, fishing tackle, beer cans, chunks of glass, sunglasses and hats. Every time we go back, the bottom has more.
The Bigger Items Are Still Down There
Hand carried debris is the start. Our Utah Waterways Submerged Debris Atlas documents an estimated 499 submerged items across 20 Utah lakes, including 56 vehicles and 103 vessels that are individually confirmed.
A sunken vehicle carries a fuel tank, engine oil, ethylene glycol and a lead acid battery. Under the Clean Water Act, a discharge that leaves a visible sheen on the water is reportable. The U.S. Geological Survey has tracked petroleum contamination persisting in groundwater for decades at its research site near Bemidji, Minnesota.
We are building toward the recovery of submerged vehicles and vessels, and we are doing it in order: insurance, permits and commercial dive certification first. Until then, our work is volunteer dive cleanups, one bay at a time.
What a Dry Year Asks of Us
Nobody controls the snowpack. Water managers may face hard choices if this winter repeats the last one. What people can control is what ends up in the water and what gets taken back out.
A low year is a reminder that Utah's reservoirs are finite. Keeping what is left clean is work that can start now, from the bottom up.
