"This fish passage and estuary culvert replacement project is addressing a partial barrier to fish migration due to the culvert being undersized, and restoring connectivity to an estuary. Schoolhouse Creek is the largest creek on Anderson Island in Water Resource Inventory Area 15. The road, Eckenstam Johnson, is built over imported fill that cuts off the estuary from Oro Bay. The project site is at the mouth of Schoolhouse Creek and Oro Bay directly north of the Nisqually River and part of the Nisqually Reach Aquatic Reserve. The proposed project will replace the existing 4-foot round culvert with a 120-foot bridge while providing a safe roadway for the traveling public."
