A decade without a dam breathes life in to a Maine river

Ten years ago today, a demolition crew in Augusta, Maine punched a hole through a 160-year-old dam on the Kennebec River and made history.

It was the first time that the US Federal Energy Regulatory Commission ruled that the ecological value of a free-flowing river was greater than the economic value of a dam – and marked the end of a bitter decade-long fight over the dam’s fate.

Now, the Kennebec, one of Maine’s great rivers, has come back to life. Without the dam’s barrier, 2 million alewives returned to the river this year, making it one of the largest river herring runs in the United States. Anglers are increasing fishing for bass and other fish. Atlantic sturgeon – the Kennebec’s largest fish that can grow up to 10 feet in length – are regularly seen leaping out of the river from Augusta to Waterville during their mid-summer spawning migration. Canoe and kayakers regularly paddle along the scenic waterway.

The dam removal was touted at the time as a symbol of a new era, one where dams would face increasing scrutiny over their environmental damage. Environmentalists predicted dozens – perhaps more – dams would be ordered removed when their licenses expired.
