1 However, the restoration actions the Port of Everett will perform concurrently in the buffer area is likely to improve this critical habitat. Bull Trout and Critical Habitat Salvelinus confluentus—Threatened,listed November 1, 1999 ' Critical habitat designated October 18, 2010(75FR63898) There is limited knowledge about the anadromous form of bull trout or their activities in nearshore waters of Puget Sound (R2 Resource Consultants, Inc., 2008). Some data do indicated that those bull ' trout present in the Snohomish River Basin indicate they have annual migrations that start late winter and peak in spring or mid-summer (Pentec 2002a;Goetz et al. 2004). It is believed that larger fry and adults migrate to marine areas and utilize shallow nearshore habitats. "Anecdotal information in ' central Puget Sound suggests that bull trout aggregations are associated with surf smelt spawning beaches,presumably because bull trout feed on this forage species.Most anadromous bull trout move back to fresh water by late summer, although not necessarily into the same systems from which they emigrated. Tagging data indicate that bull trout" (Goetz et al. 2004). "Most mature adults migrate to upper-river spawning grounds beginning in late May and continuing through mid July. Subadults may remain in marine areas as late as September before migrating to lower-river freshwater habitats,where they reside during the winter months (Goetz et al. 2004). Overwinter habitats for subadults have been identified in the Snohomish River between river miles (RM) 12 and 16 (Pentec 2002b).The bull trout population in the Snohomish River has been separated into two populations, those found in the ' Snoqualmie River Basin and those found in the Skykomish River Basin. Although adult population numbers are unknown for the Snoqualmie River Basin,they have been estimated by the WDFW using redd counts for the Skykomish River Basin (Pentec 2000b). Bull Trout are documented within the Snohomish River. Local salmonid habitat assessments suggest that the immediately defined shoreline of the Snohomish River rates low for habitat quality relative to the wetland/marsh complexes on the opposite bank and further upstream and downstream. Refer to Section 4.4. Bull Trout may be in the project area during project activities, however, due to lack of habitat within the Action Area and the project proposing upland work only, direct effects from the project on Bull Trout salmon are not likely. Temporary increases in terrestrial noise will have no effect on fish species due to the highly-increased ' attenuation rates of soundwaves moving through water. In addition, the terrestrial noise action area of the project is a radius of 81 feet and project activity will occur, at most, 50 feet from the bank of the Snohomish. Therefore, noise effects from the project will have no effect on bull trout. 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 Bull Trout. The indirect and direct effects are expected to be highly discountable. Project activities will only occur in the upland area of the site and not in the riparian area of the Snohomish River. In addition, the project will utilize all best management practices to prevent sedimentation runoff and there will be no alteration of the riparian area of the river; therefore, the proposed activities will have No Effect on Bull Trout Critical Habitat. However, the ' improvements the Port of Everett will perform in the buffer area is likely to improve this critical habitat.
