Floods and canal repairs

In 1920 the berm side of the Conococheague Aqueduct failed. The level between dam 5 and lock 44 was drained of water as the entire wall collapsed into the Conococheague Creek in Williamsport. At the time of the wall failure a boat was in the process of crossing and it was swept over the side of the aqueduct and ended up in the creek. Towns people from Williamsport crowded onto the canal to survey the damage.

In 1920 the berm side of the Conococheague Aqueduct collapsed into the Conococheague Creek. The current created by the canal water flowing over the edge of the aqueduct caused a canal boat to plunge into the creek below. The canal boat stayed in the Conococheague creek until the 1936 flood carried it under the aqueduct and down the Potomac Valley.
