What is a barrier? How does it impact fish passage?

Man Made Barriers:
Dams
Weirs
Culverts

Naturally Occurring Barriers:
Beaver Dams
Large Woody Debris
Landslides

Snake River Dams
Removing the lower snake river dams would be a vital part in restoring thousands of miles of habitat and ensuring salmon and trout runs for years to come
