Yellowstone reveals plan to halt spread of invasive brook trout

The recent discovery of brook trout in a popular Yellowstone National Park creek has biologists hustling to remove the nonnative species.

The recent discovery of brook trout in a popular Yellowstone National Park creek has biologists hustling to remove the nonnative species.

The trout were found in Soda Butte Creek, a popular fly-fishing destination in the northeastern portion of the park.

Brook trout are invasive and threaten native Yellowstone cutthroat trout. If left unchecked, brook trout could spread from Soda Butte Creek throughout the Lamar River watershed.

The park, in coordination with Montana Fish, Wildlife & Parks and Custer Gallatin National Forest, will close a 9.6-mile stretch of Soda Butte Creek to the public Aug. 14-18.

During this period, biologists will kill brook trout with EPA-approved rotenone treatments.

Beforehand, during the week of Aug. 7, biologists will capture Yellowstone cutthroat trout via electroshocking. They’ll be kept alive in upper tributaries away from the treatment area.

A similar treatment program was successful in removing brook trout from Soda Butte Creek after they were discovered in 2015.

Cutthroat trout are the only trout native to Yellowstone National Park. They’re prized by anglers and play an important ecological role throughout the Greater Yellowstone Ecosystem.

Angler breaks Colorado’s oldest fishing record, is coy on details

A 75-year-old record for brook trout was broken by a slim margin at Monarch Lake, a fishery officials suspected was home to the state record.

A 75-year-old fishing record, the oldest in Colorado, was broken when Tim Daniel of Granby landed a 7.84-pound brook trout at Monarch Lake, a fishery officials suspected was home to the state record.

“When I headed out to fish that day with my friend Karen and four-legged friend Moose, I had no intention of breaking a record,” Daniel told Colorado Parks and Wildlife. “I wasn’t sure what I had hooked, but I knew it was big.”

The brook trout measured 23¼ inches in length, had a 15-inch girth, and surpassed the previous record by a slim margin. The old mark was 7.63 pounds caught by George Knorr in Upper Cataract Lake in 1947.

Asked by the CPW where and what he used to catch the fish, Daniels said “in the water and with a hook.”

Though we do know it was caught at Monarch Lake, Daniels didn’t reveal to CPW what he used to catch the trophy trout, remaining coy about that and other details.

CPW Aquatic Biologist Jon Ewert inspected the fish the day it was caught on May 23. The CPW announced the approval of the record on Friday.

Ewert wasn’t too surprised the record came from Monarch Lake, saying, “We always suspected that Monarch Lake had the potential to produce a state-record brook trout. This is a real testament to the quality of our angling opportunities in Grand County.

“It couldn’t have happened to a more deserving angler than Tim. He’s just one of those guys that is always out there on the water and as a result, has an intimate knowledge of the subtle details necessary to be so successful.”

But just don’t ask him to reveal them.

Incidentally, the oldest-standing fishing record in Colorado is now a 4.44-pound white bass caught by Pedro Martinez from Blue Lake in 1963.
