chinook salmon

This is something you don't get to see every day. After a huge explosion, a dam which helped power 7,000 homes for almost 100 years was partially destroyed - so that salmon can swim freely down a river. Demolition crews detonated explosives in a drain tunnel at the base of the 12-story hydro-power Condit Dam, on the White salmon River in the Pacific Northwest, that's in the state of Washington.
