Puget Sound dam jeopardizing salmon, endangered orcas
SOUTH KING COUNTY, Wash. -- The Green River is cut in half by two dams that keep adult salmon from going upstream to spawn and juveniles from migrating down to the ocean. The current state of one of the dams is threatening three endangered species. The first dam has been blocking fish habitat for about a century. Tacoma Headworks Diversion Dam east of Ravensdale is how the City of Tacoma gets its water. Tacoma Water was tasked with building an upstream trap-and-haul facility and finished construction in 2005.
