In recent years, hundreds of lowhead dams have been removed from American rivers in an effort to restore the traditional spawning grounds of native fish with notable nearby dam removals occurring in Charlottesville and in Fredericksburg [REF].
Such fish as shad, herring, and striped bass-which make their migratory spawning runs between March and early June-had been blocked by Bosher, which made migration impossible for at least 300 miles upstream in the James, the Rivanna River, and other tributaries.
