Cutthroat Trout Leaping in Yellowstone! Yellowstone Live!



This 3-minute-footage collage shows Old Faithful with a Full Moon, cutthroat trout, Harlequin ducks, grizzly bear and cub, cinnamon black bear, American pika, Sandhill crane, bison, osprey, bighorn sheep, UAV footage near Cooke City, trumpeter swan, old faithful eruption at sunrise and during the full moon.


The LeHardy Rapids are a torrent on the Yellowstone River, not far from Fishing Bridge. In the spring, native cutthroat trout rest in the shallow pools along the banks of Lehardy Rapids before using surges of energy to bound up the rapids on their way to spawn under Fishing Bridge.


In the wild heart of Yellowstone National Park, the Yellowstone cutthroat trout reigns as a true native survivor, perfectly adapted to the park’s cold, pristine waters. These beautiful fish, with their striking red “cutthroat” markings under the jaw, have called the Yellowstone River and its tributaries home for thousands of years. Each spring, as snowmelt swells the river, thousands of these silver-scaled athletes gather in the shallow pools below LeHardy Rapids. Driven by powerful instinct, they launch themselves in spectacular leaps against the rushing whitewater, using bursts of speed and explosive energy to conquer the torrent and reach the gravel beds upstream near Fishing Bridge.

Scientifically, this upstream migration—known as a spawning run—ensures their eggs are laid in clean, oxygen-rich gravel where cold water constantly flows over them, giving the next generation the best chance to hatch and thrive. It’s a thrilling display of nature’s resilience: watching these determined fish launch like living rockets, twisting and flashing in the sunlight, feels like pure wilderness magic—a reminder of why Yellowstone’s untamed rivers continue to inspire awe and wonder.


A River's Symphony: The LeHardy Rapids

Imagine a pristine river, its waters a shimmering tapestry of emerald and sapphire. This is the Yellowstone River, a testament to nature's enduring beauty. As it courses through the heart of Yellowstone National Park, it creates a symphony of sounds that echo through the canyon walls.


One such masterpiece is the LeHardy Rapids, a torrent of whitewater that dances and frolics, a testament to the river's raw power. Here, in the shallow pools along the banks, a remarkable spectacle unfolds each spring. Native cutthroat trout, their scales shimmering like liquid silver, gather, preparing for their annual migration. With a surge of energy, they leap and bound, defying the current as they ascend the rapids, their journey a testament to their resilience and instinct.


The Yellowstone River, a lifeline flowing through the American West, is a rare gem. Yellowstone National Park’s cold, pristine rivers, lakes, and streams host a rich variety of aquatic life shaped by the park’s volcanic geology and clean mountain waters. Native fish include the iconic Yellowstone cutthroat trout (silver fish with red jaw markings, famous for leaping rapids to spawn), Westslope cutthroat trout, Arctic grayling (elegant sail-like dorsal fin), mountain whitefish, and smaller species like mountain sucker, longnose dace, speckled dace, redside shiner, mottled sculpin, and chubs. Non-native fish such as rainbow, brown, brook, and especially invasive lake trout (a large predator harming cutthroat populations) also live here.


Amphibians include Columbia spotted frog, boreal chorus frog, boreal toad, and blotched tiger salamander. Abundant aquatic invertebrates—mayflies, stoneflies, caddisflies, and crustaceans—form the base of the food web, while unique extremophile microbes thrive in hydrothermal hot springs and geysers. Together, these creatures support a complex, interconnected ecosystem that scientists study to understand resilience and conservation.
