Once the water level had dropped to meet the

downriver level the gates opened and the boat left the lock. The man we spoke with said summer weekends were pretty busy with pleasure craft but there were still barges that used the lock as well. He said there was a barge that went through twice each day, once downriver and once upriver. If we plan to visit the lock again I will call and find out the aproximate time the barge travels through the lock. I recall visiting a lock and dam on the St. Lawrence Seaway in NY. The boys remembered seeing the much smaller lock and dam on the Cape Fear River in NC.
