DESCRIPTION
The Northwest Marine Technical Institute used this grant to develop plans for a restoration project at Shoal Bay, Lopez Island, and to perform preliminary studies and community outreach for two potential restoration projects on Shaw Island. The results of this project included:
Part One: Developed a restoration project plan for Shoal Bay. The tidal gate situated between the lagoon and nearshore at the southern end of Shoal Bay is derelict and on San Juan County's priority restoration list. We investigated the area’s historic conditions and worked with Coastal Geologic Service to design restoration options. We documented Chinook salmon in Shoal Bay, and tagged Chinook salmon. Monitoring of Shoal Bay throughout documented the presence of Chinook, coho, and chum salmon. The tidegate area and lagoon were assessed for habitat value and for projected benefits of removing the tidegate. Insect traps set monthly obtained a baseline data of insects potentially used by juvenile salmon. A public presentation focused on the habitat quality and proposed project plan.
Part Two: Developed a restoration project plan at Neck Point causeway on Shaw Island. Storm activity and human alterations have resulted in reduced flooding and drainage of the marsh. Community Board involvement and landowner permission resulted in an agreement to design a solution. Preliminary designs were drawn up and await final approval from the community. Insects collected monthly established a baseline of potential prey for juvenile salmon.
Part Three: Evaluated a potential restoration project involving a lagoon and a wetland at Neck Point isthmus on Shaw Island. A roadway and a culvert constricted the connection with the nearshore and resulted in reduced flushing and the deposition of large woody debris. The lagoon is now filled with woody debris that has no way to disperse. The landowners in the area are interested in redesigning the openings so flow can be reestablished.
