Final Environmental Impact Statement (EIS) for the Duwamish-Green Hatcheries

June 28, 2019


In 2019, NOAA Fisheries completed its final Environmental Impact Statement (EIS) evaluating effects of our proposed approval of 10 hatchery programs in the Duwamish-Green River basin of Puget Sound, in Washington State.

In the spring of 2017, NOAA Fisheries released for public comment its draft EIS analyzing effects of our proposed approval of the 10 hatchery programs. The programs are described in Hatchery and Genetics Management Plans (HGMPs), prepared by the Washington Department of Fish and Wildlife (WDFW), Muckleshoot Indian Tribe, and Suquamish Tribe (the co-managers).

In December 2018, NOAA Fisheries released a draft supplemental EIS, which analyzed the effects of an additional alternative that was not analyzed in the draft EIS. The analysis of the new alternative in the draft supplemental EIS included an increased number of fall Chinook salmon that would be produced by the Soos Creek Chinook salmon hatchery program.

Public comments on the draft EIS and draft supplemental EIS were considered and are addressed in this final EIS.
