-50 ft. Dredging Program - Middle Harbor Enhancement Area
Benefiting the Environment
Middle Harbor will become an ecological reserve of shallow bay and shoreline habitats. Commercial species, such as Dungeness crab, flatfish, anchovy, herring, and perch, live and feed in these shallow areas often using them as nurseries for their young. A smorgasbord of worms, clams, small shrimp and other creatures burrow, wriggle, crawl and swim on the bay bottom -- tasty morsels to young fish. These small creatures feed on a stew of algae and bits of plants in the water and sediment. Algae grow in great quantities in the sunlit shallows providing the base for this web of life.
The shallows created in Middle Harbor will be a calm, clear water area and will be planted with eelgrass, a marine plant with long, green leaves. Eelgrass is a productive habitat that supports diverse species. The sturdy roots of eelgrass shelter a community of worms, crabs, shrimp and snails. The tangle of leaves stills currents creating a refuge for small fish, shrimp and microscopic life. Other animals graze the algae attached to the eelgrass further increasing the richness of the habitat.
Shallow water habitat is rich with microscopic plant and animal life, clams, worms, crabs and a diverse assemblage of fish species. Eelgrass shelters juvenile fish and other animals.
