Crews breached a nearly century-old hydropower dam on Washington's White Salmon River Wednesday.
Water poured from a hole in the 99-year-old Condit Dam after crews with Portland-based utility PacifiCorp used explosives to blast through concrete in the base of the dam.
PacifiCorp is removing the dam after deciding it would be cost prohibitive to add fish ladders for salmon and steelhead.
The dam sits about 3 miles upstream of the river's confluence with the Columbia River in Washington's south Cascades.
The 125-foot dam will be the second-highest dam breached in the country when crews blast through concrete Wednesday. Last month, the 210-foot Glines Canyon Dam and the 108-foot Elwha Dam were breached to restore salmon runs to Western Washington's Elwha River on the Olympic Peninsula.
