Port Louisa National Wildlife Refuge in Iowa was established for the protection of migratory birds. It is located along the Mississippi River Flyway, one of the major routes for migrating waterfowl. Key goals of the refuge are to conserve and enhance the quality and diversity of fish and wildlife and their habitats; and to restore floodplain functions in the river corridor.
