The water level of Lake Michigan/Huron was up an inch in the last week, and up 4″ in the last month. The lake is 14″ higher than it was one year ago and is now just 5″ below the long-term average. Lake Superior is also unchanged in the last week and up 5″ in the last month. Superior is 15″ higher than it was last year at this time and is a full 7″ above the century average. Lake Erie is up 1″ in the last month and up 7″ year-to-year. Erie is 4″ above average water level and Lake Ontario is unchanged in the last month, up 2″ in the last year and is 6″ above the long-term average. Lake St. Clair is up 1″ in the last month, up 7″ in the last year and 2″ above the century average. Outflow out of Lake Superior down the St. Mary’s River into Lake Huron is expected to be above average through the early summer. Outflow from Lake Erie down the Niagara River, over Niagara Falls and into Lake Ontario is also expected to be above average flow.
The 14″ of water added to Lake Michigan is (at 390 billion gallons per inch) 5.46 TRILLION gallons of extra water in the lake since one year ago…a pretty amazing jump.
The south mid-Lake Michigan buoy remains at a very cold 39°. The north mid-Lake Michigan buoy is at 38°. Great Lakes waters remain “dangerously cold”…23 drownings in the Great Lakes so far this year. Also: ” fuel could leave boaters stranded at sea“…ancient shipwrecks…rising water levels take pressure off dredging…and high tech. charter fishing.
