Description Saltwater intrudes into Salmon Bay as a result of operation of the Hiram Chittenden Locks, which connect the Lake Washington Ship Canal with Puget Sound. Depending on the levels of salinity present, sediments in certain areas may be classified as marine, low-salinity, or freshwater. These classifications can affect sediment cleanup decisions.

To evaluate the appropriate classification, sediment pore water salinity levels in Salmon Bay and Lake Union were determined using conductivity and temperature measurements.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
