East Pass in Bay County was a natural inlet that closed after construction of the federal navigation channel into St. Andrews Bay in support of the Panama City Harbor project, which captured most of the Bay’s tidal prism. In 2001, the County re-opened East Pass to evaluating the impact, performance and “success” of the re-opening. The pass re-opening improved water quality in the eastern arm of St. Andrews Bay in an area of significant ecological importance, but there were no definitive changes to the overall percent cover of sea grass beds.
