A dam gets blown up to help salmon

Salmon lead a very interesting life.

Starting out as small eggs in a stream bed, they hatch and begin their journey downstream towards the ocean. They spend a couple of years in the streams and rivers growing to a juvenile stage. The young adult salmon then head out to sea and spend several years swimming around. Once they have fully matured, they will swim back to their original stream or river to spawn, or lay their eggs in the water.

Their upstream journey is a challenging one, swimming upstream against rugged rapids, leaping over rocky waterfalls, traversing fish ladders, avoiding fishermen nets and hooks, and staying clear of hungry bears.

But no salmon can overcome the difficulty of traversing a dam!

For 98 years, the 125-foot high Condit Dam in southeastern Washington State, USA, held back the White Salmon River, creating a serene lake, but choking off the waterway to salmon. So, in an historic effort, the dam was dramatically breached, and ecologists hope the increased flow of water will restore the waterway to fish and other aquatic organisms, as well as the birds and mammals that rely on them.
