Great Lakes Water LevelsSeptember 13th, 2013 at 10:32 am by Bill Steffen under Bill's Blog, News, Weather
Here’s a 10 AM picture from the GLERL cam at the Muskegon Channel. There’s a boat heading out and the flag is standing out in the brisk, north wind. The big story continues to be the large increase in the water levels of all of the Great Lakes in 2013. The water level of Lake Michigan is unchanged in the past week, but is 7″ higher than one year ago, which means the lake has added 2.73 TRILLION gallons of water in the last 12 months. Ditto for Lake Huron since Lake Michigan and Lake Huron are connected at the Mac. Bridge. Lake Superior is up 2″ in the last month (at a time when the level is usually falling) and is now a full 11″ higher than one year ago! That represents an increase of 6.07 TRILLION gallons in the past year. The lake is now just one inch below the average level and Superior is 14″ below the highest level of 1985, but 19″ above the lowest recent level of 2007. Lake Erie is 8″ higher than one year ago and is exactly at the long-term average. Lake Ontario is 12″ higher than one year ago and 4″ higher than the long term average.
