Shutdown Notice
Due to the lapse in federal appropriations, this website will not be updated until further notice. Where public access to refuge lands does not require the presence of a federal employee or contractor, activities on refuge lands will be allowed to continue on the same terms as before the appropriations lapse. Any entry onto Refuge System property during this period of federal government shutdown is at the visitor's sole risk. Please read this important updated message about the closure of National Wildlife Refuge System facilities during the shutdown, and refer to alerts posted on individual refuge websites for the status of visitor facilities and previously scheduled events that may still occur during the shutdown.
