Fishing Battery (also known as Donahoo Battery and Shad Battery at times) is an artificially constructed island, created to allow fishermen to transfer their catches to paddleboats whose draft barred them from entry to Havre de Grace. In 1851 Congress appropriated $5000 to erect a light on the island; this light was constructed in 1853 by John Donahoo, the last light he built on the Chesapeake Bay.
