The last ship of the season has passed through the locks at Sault Ste. Marie. The locks will be closed for maintenance and until warmer weather returns in the spring. Over 75 million tons of cargo passed through the locks since last spring. That was up slightly from 2011. Six inches of snow fell at S. Ste. Marie on Thursday. They also had 5.8″ of snow at Honor in Benzie Co. and 5.3″ at Williamsburg near Traverse City. Here’s more. The ice jam at the Rogers Pond continues to back up some water in yards of homes near Big Rapids. The National Weather Service has issued a Flood Watch for the Muskegon River upstream from the Rogers Dam. Gale Warnings are out for Lake Michigan. There’s a Snow Advisory for the Eastern U.P.
The water level of Lake Michigan/Huron is down one inch in the last month and down 16″ in the last year. The lake is now at the lowest level it has ever been at in the month of January (one inch below 1965). Many are blaming the drop on dredging in the St. Clair River. Over the last two-year period, precipitation is actually a little above average in Grand Rapids. Lake Superior is only down 1″ in the past year. 30% of the equation for the water level of Lake Michigan/Huron is the water that comes down from the St. Mary’s River from Lake Superior. Lake St. Clair is up 4″ in the past month. Lake Erie is up 1″ in the last month and Lake Ontario is up 5″ in the last month. The Grand River has been running above average flow this week. Here’s an update on dredging the Kalamazoo River in Saugatuck/Douglas and an update on the Asian Carp and the Great Lakes. The city of Grand Haven now owns the two lighthouses on the south breakwater. Ewww! Here’s an update on stocking Lake Michigan with salmon.
