In a win for the eco-system, the largest dam removal in the Pacific Northwest in 40 years began on Tuesday with blasts of 4,000 pounds of explosives by Portland General Electric.

Marmot Dam a 58-foot-high structure, originally built in 1909, will be removed and the site restored as part of the decommissioning of the entire Bull Run project.
Removing the two dams, in coordination with 23 environmental, governmental and civic organizations, will allow the Sandy to flow freely from Mt. Hood to the Columbia River. Winter steelhead, spring Chinook and coho salmon, all listed on the federal Endangered Species Act, need free flowing rivers to survive.
