Arrowhead Lagoon (AL) is a nearshore pocket estuary located along the north shore of Camano Island. The lagoon is located along the path of currents from the Skagit and Stillaguamish Rivers, thereby providing refuge, foraging, and rearing opportunity for fry migrant Chinook, as well as a nursery and nearshore habitat for other estuarine/marine fish species.
Skagit River System Cooperative (SRSC), in cooperation with local landowners, proposes to restore approximately 2.0 acres of intertidal habitat within the eastern portion of AL. Currently natural ecosystem function is impaired due to manmade constrictions within the inner lagoon. Actions will include removal of trail fill, a failing culvert, and a short bridge; construction of a new bridge; removal of fill along the northern interior shoreline; and revegetation in selected areas.
This restoration proposal is timely because local landowners, represented by the Eagle Tree Estates Property Owners' Association (ETEPOA), have requested assistance for a failing culvert in the existing beach access trail fill. Removal of fill and construction of a spanning bridge would result in significant ecological improvement compared to the proposed culvert replacement alone. SRSC will work closely with the property owners to address beach access concerns and maximize restoration
