MAINE: Costs, fish, property values are factors in the future of 3 Mousam River dams

December 29, 2015 — KENNEBUNK, Maine — A Kennebunk electric utility is weighing whether to remove the three lowest dams on the Mousam River or face potentially costly upgrades to restore fish passage to a river that once hosted large runs of spawning fish.

Trustees at Kennebunk Light & Power District have until March 2017 to decide whether to seek federal relicensing of three dams that the nonprofit utility owns on the Mousam River or propose several alternatives for the facilities. One option under serious consideration – and being pursued by local conservationists and sportsmen – is the removal of some or all three of the dams, including the large Kesslen Dam located in the heart of downtown Kennebunk.

The Mousam River is the only major river system in Maine emptying into the Gulf of Maine that lacks any methods for fish such as American shad, alewives or Atlantic salmon to bypass the dams, effectively blocking them from accessing more than 300 miles of watershed. Removing the three dams would allow the lower 9 miles of the Mousam River to flow freely – although an additional 12 dams remain on the upper stretch of river – and is part of an intense river restoration push in Maine.

Conowingo Dam fish-lift overhaul urged to restore Susquehanna’s shad, eels

August 12, 2015 — Federal wildlife officials are calling for Exelon Corp. to overhaul its fish lifts at Conowingo Dam, arguing it’s the only way to revive the Susquehanna River’s depleted stocks of the iconic American shad, eels and other once-important fish.

In comments submitted to the Federal Energy Regulatory Commission, the U.S. Fish and Wildlife Service recommended the lifts be rebuilt and enlarged as a condition of renewing Exelon’s license to generate hydroelectric power at Conowingo.

The service also wants the power company to help more eels get upriver — by truck for now.

Rebuilding the dam’s fish lifts could cost millions of dollars. Exelon is reviewing the wildlife service’s prescription for improving fish passage, said Robert Judge, a spokesman for the Chicago-based parent of Baltimore Gas and Electric.

The service’s proposal comes after years of negotiations between Exelon and officials from Maryland, Pennsylvania and federal agencies over the dam’s relicensing, which has been hung up in part by debates over how to deal with a buildup behind the dam of bay-fouling sediment and nutrient pollution washed down the river.

The company’s license to operate Conowingo expired last year, but the federal commission has extended the permit while the parties attempt to work out their differences over the sediment buildup, fish passage and other issues.

“We’ve reached a crucial period,” said Genevieve LaRouche, supervisor of the wildlife service’s Chesapeake Bay field office. “It’s a 46-year license. It’s kind of a once-in-a-lifetime opportunity to do something.”

LaRouche said the service hasn’t costed out the upgrades yet. But state and federal officials have previously said current fish passage facilities could be tweaked for less than $1 million, while replacing both fish lifts could run $24 million or more.
