Dam Demolition Begins On Sandy River
POSTED: 12:20 pm PDT July 24, 2007

SANDY, Ore. -- Explosives cracked the concrete face of the Marmot Dam on Tuesday, beginning Portland General Electric's demolition of two hydroelectric dams on the Sandy River.
Demolition, which is expected to last two months, started on the 47-foot Marmot Dam on Tuesday afternoon. Following the detonation, heavy equipment began taking apart the concrete structure.
PGE officials said the 22-megawatt capacity dam system is too costly to maintain, particularly considering new environmental protections for salmon and steelhead.
"The bottom line is that (the demolition of the dam) is good for fish and saves our customers money," Peggy Fowler, CEO and president of Portland General Electric, said at a ceremony just before pushing down on a plunger-style detonator straight out of the Old West.

It will cost $17 million to remove the dams and it's the largest dam removal project in Oregon's history. When the dams are fully removed, the Sandy River will be a free-flowing river for the first time in nearly a century.
Marmot Dam was part of the Bull Run Hydroelectric Project that went on line in 1913 to provide power to a younger Portland decades before the more massive dams were built along the Columbia River. The Bull Run project provides enough electricity to power more than 10,000 homes.
The project includes more than a mile and a half of canals and tunnels that connect a three-mile wood box flume from Marmot Dam to the Little Sandy River just above Little Sandy Dam.
Water from the Little Sandy River is diverted into Roslyn Lake, then returned to the Bull Run River after passing through a powerhouse.
PGE is donating about 1,500 acres on the Bull Run Project for fish and wildlife habitat, and for public recreation. The area will be the centerpiece of a planned 9,000-acre natural resource and recreation area, officials say
