Howard

In 1962, Howard Hanson Dam (HHD), a flood control dam, was completed at River Mile 64.5, which is the downstream boundary of this sub-watershed. HHD is also a complete barrier to upstream and down stream adult migration. The large flood control dam and associated reservoir interrupts the natural flow of sediments and large woody debris to lower mainstem Green River reaches. It also chronically floods upstream habitat when the reservoir is full. The Army Corps of Engineers and the City of Tacoma are working together to identify and implement methods of getting fish upstream and downstream past the two dams. Efforts are also being made to better understand the impact of flows on salmon downstream.
