Thanks everyone,
@ GTN the creek feeds into the Rappahanock river and then into the Chesapeake Bay so we have access out to the bay at 5' MLW. So we can sail out with a low draft or retractable keel. For the winter I put the container pots into the pond and turn the ceramic pots over, in place, for the winter. Only issue is I have to check for animals in the Spring, I have found mice, snakes, frogs, slamanders, etc.
