ZEBULON PIKE LOCK AND DAM
Work on the lock and dam, named for famed explorer Zebulon Montgomery PIKE, began on February 2, 1934. The facility was first put into operation on September 10, 1937.
The eleventh of twenty-eight LOCKS and dams between St. Paul and Minneapolis, Minnesota, and St. Louis, Missouri, the locks cost $1,470,000 to construct. The dam, at 1,278 feet one of the largest on the river, helped maintain the nine-foot channel for river traffic.
