- 244 - Telescope U. S. Army Corps of Engineers Vessels Built or Operated on the Great Lakes-Part One By the Rev. Edward J. Dowling, S. J. President Jefferson established the Engineers' Corps of the U. S. Army in 1803, and in 1815 the Corps began to undertake work on channel dredging and maintenance. Powered vessels operated by the Engineers' Corps are listed in Merchant vessels of the United States from 1888 to 1942 inclusive. Unfortunately, USMV lists few of the non-powered barges and scows used by the Corps. USMV is also very sketchy in its information on previous history of vessels purchased by the Engineers at various times. A list of present day equipment is published by the Army Engineers' Corps and lists all floating equipment as of 1962. Missing from this list, however, is the place of build of the ships and the name of their shipbuilders. The following list is of Engineers' Corps vessels 35 feet in length or larger, and has been put together from both sources mentioned above. Additional information from our readers will be gratefully appreciated by the Dossin Great Lakes Museum, Telescope, and the author.
