The Great Lakes, water levels rising!

After reaching historic lows in 2013, water levels in the Great Lakes are now abruptly on the rise, a development that has startled scientists and thrilled just about everybody with a stake in the waterfront, including owners of beach houses, retailers in tourist areas and dockmasters who run marinas on the lakeshore.

Lakes Michigan, Huron and Superior are at least a foot higher than they were a year ago, and are expected to rise 3 more inches over the next month. Lake Ontario and Lake Erie are 7 to 9 inches higher than a year ago.

that Easterners around the Great Lakes have shown.

Having lived in the region twice, I still find the remembrance shocking.

it's been raining (seems like) almost every day for the last couple of weeks. All that runs into the lake.

11. Not all. There's a split down the middle of the state that sends half of it to the Mississippi.

But you have a point that all the snow and now precip is adding to the rising water levels. I had a friend post photos of flooding on the upper Mississippi at Lake Pepin - something that rarely happens.

I'm puzzled by why scientists would be "startled" by nature's response. It's true we would have had a few more years of low annual precip. But what we've had this year isn't all that far out of the ordinary and just likely to happen.

maybe it kept the water levels up?

On Ontario, most of our snow came up from storms on the Gulf and East Coast rather than from across the Great Lakes. Maybe this added some to the total watershed.

good thing: when the levels stay constant for a while , people with lake front property go ballistic if there is any change in the level at their door step. There has been an effort to set up an oscillation on Lake Ontario to encourage the development of wet land, and property owners are screaming!

There is a certain amount of control on most of the Lakes via various locks - on Ontario the locks on the St.Lawrence and the Erie Canal give some control on how much water comes and how much goes out.

In the long run the lake floor is heaving up as the lakes evaporate since the last glacial maximum.. In Chicago the boundary of ancient Lake Michigan is about 8 miles inland on the north side. There is a plaque on the 13th tee at Ridgemoor. Beverly and Ridge Country clubs on the south side are on the same morraine.
