August 6 News: Mass Fish Die-Offs Increasing In Warming U.S. Rivers

Thousands of fish are dying in the Midwest as the hot, arid summer dries up rivers and causes water temperatures to climb in some spots to nearly 100 degrees.

About 40,000 shovelnose sturgeon were killed in Iowa last week as water temperatures reached 97 degrees. Nebraska fishery officials said they have seen thousands of dead sturgeon, catfish, carp and other species in the Lower Platte River, including the endangered pallid sturgeon.

Biologists in Illinois said the hot weather has killed tens of thousands of large- and smallmouth bass and channel catfish and is threatening the population of the greater redhorse fish, a state endangered species.
