 The lock, which was opened in 1916, has a single chamber and is long, wide, deep, and has a lift of approximately 14 feet (4.3 m).Although it is the first lock encountered by vessels passing from the Hudson River into the Great Lakes by way of the New York State Canal System, and it is sometimes referred to as lock "E-1," it is not part of the Erie Canal (which officially has no "Lock 1"), nor maintained by the New York State Canal Corporation.Both the lock and the dam were built and are currently operated by the U.S. Army Corps of Engineers; as of September 2006, it was listed as being in "Operational" condition.
