In a bid to recover Snake River salmon and end decades of conflict, U.S. Rep. Mike Simpson is proposing a $33 billion infrastructure and community investment strategy that would breach the four lower Snake River dams and reorder much of the fish, energy and commodity transportation systems of the Pacific Northwest.

If turned into legislation, passed and implemented according to Simpson’s timeline, Lower Granite Dam would be breached in the summer of 2030 and the river that was swallowed by slackwater 55 years earlier would reemerge. The breaching of Little Goose, Lower Monumental and Ice Harbor dams would follow and the entire stretch of the river would return to its free-flowing state by 2031.
