Great Lakes on the Rise in 2020

mLive reports that the six-month water level forecasts show a high-end forecast that could surpass all other modern water levels for some of the Great Lakes:

For the last three months, Lake Michigan and Lake Huron (which shares the same lake water level because they are linked) have set monthly record water levels. The monthly record water levels are expected to continue into summer. If we get significantly higher than usual precipitation, the water levels could slosh over the highest level ever recorded since good water level measurements began back in 1918.

…The upper end of the possible outcomes would take Lake Michigan and Lake Huron 5 inches higher than October 1986, the highest water level recorded since records began in 1918. July or August of this coming summer would be the months that could happen.

That would be a devastating high-water level for cities and beaches along the Lake Michigan and Lake Huron shoreline.

Remember one inch of water on Lake Michigan and Lake Huron is 800 billion gallons of water. If this summer’s water level reaches that upper end, Lake Michigan and Lake Huron would have 4 trillion gallons more water than the highest water level recorded by in the fall of 1986.

Read on for more about Lakes Superior (probably not dangerously high) and Erie & Ontario (also likely to be dangerously high).
