This summer, a century-old dam on the Salmon River in northern Franklin County was removed. The structure was deteriorating and posed a safety hazard. Fort Covington decided to remove the dam, rather than pay for costly repairs. Green groups say the project will eventually restore crucial fish and bird habitat. But two months after the work was done, a massive plug of silt and sand still clogs the river. As Brian Mann reports, many locals worry that the Salmon River could be permanently damaged.
