Lahontan cutthroat trout are successfully reproducing in the lower Truckee River in what experts are calling a major milestone in efforts to restore the population once on the brink of extinction.
Last year, cutthroats raised from a strain of a remnant population in the mountains near the Nevada-Utah line spawned upstream from Pyramid Lake for the first time in nearly 80 years.
Now, U.S. Fish and Wildlife Service officials have documented about 1,000 newly hatched baby cutthroats swimming in the river after a second spawn this spring. They suspect as many as 45,000 may have hatched in recent weeks.
