Adds Fishkill Creek to the definition of inland waterways

This bill adds Fishkill Creek in Dutchess County to the official list of inland waterways defined in New York State law. It directly updates a legal definition in the Executive Law without creating new regulations or affecting specific communities or businesses. The change is administrative, simply expanding the existing list of named waterways for official reference. As a procedural update, it has no direct policy impact beyond clarifying the legal scope of "inland waterways."
