PORT ANGELES,

Clallam County —

The end of an era arrived Wednesday with the final shutdown of two dams on the Elwha River.

The dams were unplugged from the Western power grid and their mighty turbines stilled, in preparation for taking both dams down beginning in September.

"We are cutting the heart out of these old girls," said Kevin Yancy, manager of the Elwha hydroelectric project for the U.S. Bureau of Reclamation. But their time, he acknowledged, has passed, after nearly a century of generating power that fueled development of the Olympic Peninsula.
