Great Lakes Water LevelsMay 9th, 2013 at 11:10 pm by Bill Steffen under Bill's Blog, Weather
Close-up of sunset at Pier Cove a couple days ago, from Jack Martin. Let me start by saying the water level of the Great Lakes usually goes up in April and often it goes up the more in April than any other month. However, the heavy rain that fell during the month has really boosted water levels. Lake Michigan (and Lake Huron) added another 2″ in the past week and is now up 9″ in the last month. The lake is still 6″ below the level of one year ago and 22″ below the long-term May average. However, it’s now 7″ above the lowest May level that was reached in 1964. Lake Superior has benefited from a fairly rapid snow melt and is up 3″ in the last week and 6″ in the last month. Superior is now at the same level that it was at one year ago, but is still a foot below the century average for May. Lake Erie is up 6″ in the last month, but 7″ below the century average. Lake Ontario is up 8″ in the last month and is 6″ below the century average. The lakes are expected to go up another 1-4″ in the next month.
