The Wrack

Since 2010, the Wells Reserve has been working with partners to develop an inventory of stream barriers in the small coastal watersheds of York County. These are usually man-made structures that prevent the upstream or downstream movement of fish and other aquatic organisms, due to the fact that stream crossings were not historically designed with fish in mind. The impacts of stream barriers are particularly severe on migratory fish such alewives or salmon, which move from the ocean into rivers to reproduce.
