In order to properly manage wetland resources and restore salmon habitat, the mechanisms through ...
Sediment accumulation in a manipulated bay of Puget Sound, Bellingham, WA.
Mud Bay, located in Bellingham, Washington at the north end of Chuckanut Bay, is filling with sediment at a rate greater than projected sea-level rise. This is worrisome as the bay is an important habitat for eelgrass meadows, shellfish beds, and birds. Also, Chuckanut Creek, the primary fluvial input into the bay, has ...
