  • Soo Locks open early for 2021 shipping season

    SAULT STE. MARIE, Mich., – The Detroit District’s Soo Area Office will open the Poe Lock noon, March 24, marking the 2021 Great Lakes shipping season start. The shipping industry requested an early season opening to ensure safety of the vessels. “We believe a 1200 EST opening on 24 March 2021 provides a safer timeframe for vessels to transit Whitefish Bay and the St. Mary’s River. It facilitates U.S. Coast Guard (USCG) icebreaking prior to and after the initial lock transits,” James Weakley, President of the Lake Carriers’ Association said. “The efficiency of icebreaking for the first transits is the primary driver for this request.”
  • Great Lakes water levels lower than 2020 heading into spring rise

    DETROIT- Great Lake water levels in 2021 are tracking below last year’s levels, though Lakes Superior, Michigan, Huron, St. Clair and Erie remain well above long-term average levels, according to U.S. Army Corps of Engineers officials who track and forecast Great Lakes water levels. Lake Ontario recently fell slightly below long-term average levels. The February 2021 monthly mean water levels ranged from 7 to 23 inches below levels from this time last year. Since November 2020, the Great Lakes basin experienced four consecutive months of below average precipitation. This combined with a cold air outbreak during February led to increased evaporation across the lakes and caused a St. Clair River ice jam to develop. When ice jams occur, water levels downstream of the restriction decline, while water levels upstream of the restriction rise.
