Salmon productivity in the Dungeness River has been seriously reduced by human impacts. Ten anadromous fish stocks utilize the Dungeness River: Chinook, Coho, lower Dungeness River pinks, upper Dungeness River pinks, summer chum, fall chum, winter steelhead, summer steelhead, coastal cutthroat, and bull trout. Five of these stocks are included in four populations listed as threatened under the endangered species act (Puget Sound Chinook, Hood Canal/Strait of Juan de Fuca Summer Chum, Puget Sound Steelhead, and Coastal-Puget Sound Bull Trout). Further, Lower Dungeness Pink and Upper Dungeness Pink are listed as critical under WDFW stock status inventory 2002 (NWIFC SSHIAP, 2004). The construction of dikes, roads and bridges have disconnected the river from floodplains and truncated meanders. The withdrawal of large quantities of water for the purpose of irrigation has reduced the amount of water in the river at times. The loss of riparian forests has created a severe lack of woody debris. These alterations have accelerated rates of channel down cutting and sediment accretion and severely impact the natural processes of the river (Puget Sound Salmon Recovery Plan, 2007).
