work is in progress to obliterate the Marmot Dam. Work started full tilt on Tuesday. The day started with a series of explosions. When it was all over, Marmot Dam was on its way to becoming a piece of Portland history, being the biggest dam to be destroyed in Oregon so far.

The removal of the dam will bring the area back to its pre-dam days. More importantly, it will result in salmon and steelhead gaining access to close to 100 miles of the surrounding habitat on the Sandy River.

The removal of the dam also means the Sandy River would be able to flow without any obstructions from its source in Mount Hood to its meeting point with the Columbia River, for the first time since 1912.
