More than 2,200 dams built upstream from homes or communities are in poor condition across the U.S., likely endangering lives if they were to fail, according to an Associated Press analysis.
Long-deferred maintenance, a changing climate and the construction of homes, businesses and highways below previously remote dams are all contributing to the soaring numbers.
