Yellowstone National Park in Park County, Wyoming — The American West (Mountains)
Leaping the Rapids
In June and July these rapids fill with cutthroat trout heading upstream to spawn near the lake outlet. Spawning is a life-and-death event; here at LeHardy Rapids you can witness the fierce energy it takes for the species to survive. Watch pools at the base of the rapids. A fish jumps every ten to fifteen seconds during peak spawning season in July.
Crowded with leaping fish, this stretch of river hints at what Americaís primitive fisheries must have been like.
To vault rocky ledges, a mature cutthroat cocks its body, then explodes three to four feet into the air – a height up to five times its length.
The force of backwash beneath the falls helps propel fish up and over. At steep ledges many trout appear to fail, but with repeated jumping most of them make it upstream. Far more fish are making the spawning run unseen underwater.
