Endangered fish find new home in Utah Lake
Caleb Warnock DAILY HERALD
More than 8,500 endangered June sucker have been added to Utah Lake.
The fish have been moved here from Red Butte Reservoir in Salt Lake County over the past six weeks in a special truck designed for fish transport, said Krissy Wilson, wildlife biologist with the Utah Division of Wildlife Resources.

The last fish will be trucked in this week, she said.
The fish are all at least 8 inches long and 6 to 7 years old, said Reed Harris of the June Sucker Recovery Program. They were stocked in Red Butte several years ago as a so-called back-up population, insurance in case the last remaining wild June sucker in Utah Lake die out.
June sucker occur naturally nowhere else in the world. After a decade of study, experts believe there are as few as 300 adult wild June sucker left.
Red Butte Reservoir is being drained to allow a $6 million seismic upgrade of its dam. Built in 1930, the reservoir is located at the base of Red Butte Canyon, 1.5 miles east of the University of Utah.
In addition to needing seismic work, nonnative crayfish were illegally introduced into the reservoir in recent years.
"The crayfish population has just exploded," Wilson said. "They've changed the entire ecosystem of Red Butte, so we want to fix the dam and get rid of the crayfish."
The crayfish and June sucker were removed from Red Butte at the same time. Adult June sucker were marked by inserting a plastic tag into the dorsal fin of each with a needle gun. The tag allows scientists to keep the Red Butte fish separate from existing wild June sucker in Utah Lake for study purposes, said Harris.
"We hope they add to the spawning run in the Provo River," he said. No young June sucker have lived to sexual maturity in Utah Lake for decades, despite introduction of thousands of hatchery-raised fish in recent years.
Only June sucker at least 8 inches long were brought to Utah Lake from Red Butte because they are large enough to avoid predation, Harris said.
About 1,500 smaller June sucker were taken from Red Butte to Ensign Ponds in northwest Box Elder County, said Wilson. When they reach 8 inches, they will be taken back to Red Butte or released into Utah Lake.
In the 1800s, Utah Lake was home to at least six native species of fish. Today, the June sucker and the Utah sucker are the only two remaining.
In 1986, the federal government named the June sucker an endangered species, allowing its habitat to be protected by law. Soon thereafter, nine water-user and wildlife groups with interest in Deer Creek Reservoir formed a 40-year, $40 million plan to save the fish, called the June Sucker Recovery Implementation Program.
