On July 22nd, bulldozers breached the Veazie dam in Eddington, Maine – an 830 foot strip of concrete that had separated the Atlantic Ocean and the Penobscot River for a century. It was an effort undertaken by an unlikely coalition of conservationists, fishermen, power companies and others, who came together to help restore 1000 miles of endangered Atlantic salmon habitat. Brian Graber is director of the river restoration program at American rivers, one of the partners behind the project.
