NASHVILLE, Tenn. — The snail darter, a tiny Southeastern fish that derailed a federal dam during an epic battle over Endangered Species Act protection in the 1970s, is no longer considered imperiled, officials announced Tuesday.
The fish held up construction of the Tellico Dam in Tennessee for more than two years as biologists and others fought to protect its only known habitat, the free-flowing Little Tennessee River. The battle, which went to the U.S. Supreme Court and beyond, is still sometimes cited as an example of environmentalist overreach, although the reality is much more complicated.
The dam eventually was built, with snail darters collected and transplanted into other rivers. They were also later discovered in several additional streams.
