Fish

River dams disrupt connectivity for fish, which can reduce movement, genetic diversity, and alter ecosystem processes. For some species, protecting aquatic connectivity is significant for migration and adaption to climate change. Some states, such as California and Wyoming, have policy in place to protect stream and river connectivity for fish.
