Sockeye Salmon Oncorhynchus nerka—Threatened,listed (reaffirmed)June 28, 2005 Snake River and Lake Ozette populations There is the possibility that Lake Ozette Sockeye may occur in the project action area. Sockeye adults return into freshwater streams or lakes of their birth from the marine environment and spawn only once and die. They have a wide variety of life histories, with most spawning in or near lakes. The juveniles are reared there for 1-3 years prior to returning to the sea. The fry feed on aquatic insects and plankton.The salmon usually stay at sea for 2 years. Sockeye spawning in Washington State begins as early as August and can extend through February. Those stocks spawning from August through October need adequate stream flows to provide proper spawning distributions on the spawning grounds. All sockeye stocks require extensive, quality spawning riffles for optimum production.Successful egg and juvenile survivals are dependent on clean ' spawning gravels and low to moderate winter stream flows.Those sockeye that spawn on lake shores need access to undisturbed shallow water shorelines, and clean gravels with upwelling ground water (WDFW, 2016). Sockeye require resting areas during in and out migration that provide cool water temperatures, adequate forage species,and areas of low flow current. The project riparian area is highly degraded in terms of shading vegetation and the bank is reinforced, providing little to no areas that would serve their purpose. Therefore, they are unlikely to utilize this area. ' The indirect and direct effects are expected to be highly discountable. The proposed impact actions and the minimal impacts of the project,proposed actions will have No Effect on Sockeye Salmon. The indirect and direct effects are expected to be highly discountable. Chum Salmon Oncorhynchus keta—Threatened (reaffirmed) April 14,2014 Hood Canal Summer-run ESU There is the possibility that Hood Canal Chum salmon could occur in the project action area. Chum ' salmon occur in the river systems of the Puget Sound.These include the streams of north and south Puget Sound, Hood Canal, and the Strait of Juan de Fuca. Chum populations have three run timings; summer (spawning in September and October), fall (spawning in November and December), and winter (spawning in January and February). The fall run is the largest segment of overall chum returns, typically making up 90 percent of the annual total number of chum salmon returning to Puget Sound. The summer and fall runs, although smaller, provide genetic diversity for the species and allow chum salmon to utilize a broad range of habitat types. These "age at return" patterns vary from simple (virtually all pink salmon return as 2-year old fish) to the very complex (chum salmon can return as 2-, 3-, 4-, 5-, or 6-year old fish). In the case of chum salmon, offspring from a single spawning year (called brood or brood year) can mature and return to their natal streams from 2 to 6 years later. The newly emerged fry immediately begin downstream migration to marine waters. A very small number of chum fry may reside in freshwater until the end of summer.When the fry first enter ' saltwater they assemble in small schools and reside close to shore to avoid predators.
