NEWHALEM, Wash. – Seattle City Light may begin trucking salmon over its dams on the Skagit River.

The utility’s license to operate the dams runs out in two years, and it is asking the Federal Energy Regulatory Commission to renew that for another 50 years.

The Seattle Times reports that it has agreed to demands by tribes and others to address fish passage in its application.

Native fish have not been able to access headwaters of the river since the dams were built in the early 1900’s.

The proposed plan would haul spawning salmon above the three dams and truck juvenile fish below them.

The utility says the dams’ height and location prevents other types of fish passage and dam removal has not been proposed.

Seattle City Light gets almost half of its electricity from the three Skagit River dams.
