While some pollution issues persist, the water has improved in quality. It’s now clean enough that state and federal officials are attempting to revive the Pearl Darter population by introducing fish from a private hatchery.
“This is the biggest win of my career as a biologist,” said Matthew Wagner, a biologist at the U.S. Fish and Wildlife Service.
