SAULT STE. MARIE, Mich. – The U.S. Army Corps of Engineers, Detroit District, Soo Area Office will open the Poe Lock, 12:01 a.m., March 25, marking the 2022 Great Lakes shipping season start.
The operating season is fixed by federal regulation and driven in part by the feasibility of vessels operating in typical Great Lakes ice conditions.
The Poe Lock officially closed January 16 to undergo critical repairs and maintenance during the 10 week-long winter shutdown. Maintenance crews performed a variety of critical tasks on the Poe Lock, including hydraulic steel structure inspections, miter gate bottom girder structural repair and seal replacement, miter gate pintle concrete repairs, valve machinery repairs, and dewatering system maintenance.
