During the summer and fall of 1917, as the Corps concentrated on military activities, it transferred officers out of the Civil Works District and Division commands. Colonel Lockwood, who had graduated from West Point in 1866 and had served as St. Paul District Engineer in 1900 and 1901, came out of retirement. During his 3-month appointment, a 24-hour guard was placed around the newly completed lock and dam 1 – a reminder that the Nation was at war.
