“I spoke to the angler who supplied a video of his catch that leaves little question the place he was,” wrote Koel. “There’s a good likelihood that smallmouth within the Yellowstone River will ultimately be capable to go over Knowles Falls within the Black Canyon. If that occurs we are going to sooner or later see them at Tower, the Buffalo Ranch, and the Slough Creek campground. This would be the solely nonnative fish species within the park able to preying upon semi-aquatic animals resembling snakes or fledgling waterbirds.” 

Smallmouth bass, that are native to waterways within the Midwest and East Coast, had been stocked in Montana starting in 1914 however by no means close to Yellowstone Nationwide Park, which is traditionally a cold-water fishery. The fish that was lately caught was possible a results of smallmouth bass populations slowly spreading from the Tongue River. Lately, scientists had apprehensive that smallmouth populations have been creeping closer and closer to the park due to rising temperatures. The February 19 catch justifies these fears—and alerts that an invasion of smallmouth bass, that are voracious predators and may outcompete trout, could also be inevitable.
