Deadheads - Debris Field Flooding was so severe and extensive in the Mohawk Valley in June 2006, it caused immense damage to Lock 10 on the Erie Canal. The lock had to be re-constructed which closed the canal until August 19, 2006. The flooding caused the eastern section of the canal to be afloat with huge amounts of trees and debris. The dams could be seen piled high with timber that had been caught there in the current. Even though we kept a watchful eye we still caught a couple of deadheads, but fortunately we seem to have avoided any damage.
