Middle River Nautical Chart
Baltimore County's boating heartland — thousands of slips up Frog Mortar, Dark Head and Hopkins creeks. The chart shows the marked channels (mostly 7–10 ft), Wilson Point, and the quick run past Hart-Miller Island to open Bay. Sunday-afternoon traffic is half the navigation problem.
