Habitat loss through wetland fills is also a significant factor. Table 43 summarizes the
change in area of tidal wetlands for several Oregon estuaries (Good 2000).

The only listed salmonid population in coastal Washington is the Ozette Lake Sockeye.
The range of this ESU is small, including only one lake (31 km 2 ) and 71 km of stream.
Like the Oregon Coastal drainages, the Ozette Lake area has been heavily managed for
logging. Logging resulted in road building and the removal of LWD, which affected the
nearshore ecosystem (NMFS 2008). LWD along the shore offered both shelter from
predators and a barrier to encroaching vegetation (NMFS 2008). Aerial photograph
analysis shows near-shore vegetation has increased significantly over the past 50 years
(Ritchie 2005). Further, there is strong evidence that water levels in Ozette Lake have
dropped between 1.5 and 3.3 ft from historic levels (Herrera 2005 in (NMFS 2008)). The
impact of this water level drop is unknown. Possible effects include increased
desiccation of sockeye redds and loss of spawning habitat. Loss of LWD has also
