Thanks so much for the information! It’s nice to have one’s assumptions confirmed.

Hi Catherine,

Round and Long lakes are natural – they have been modified quite a bit – but they formed at the end of the last ice age as the ice retreated and left behind pock marks on the landscape that sealed off and have been holding water ever since.

We know this as when we drill to the bottom of the lake sediments at each of these lakes and then recover organic materials at the bottom of the stack of lake sediments they radiocarbon date to about 15,000 years ago time and again. Of course there are some lakes and reservoirs in the area that are not natural and they likely outnumber the natural ones.

Thanks for reading our blog.

Greg

I beg your indulgence.

My husband just announced from his perch in his recliner – laptop in place – that there are NO natural lakes in Ohio.

Having nearly drowned in Round Lake as a toddler – my interest is peeked beyond the casual by the notion that – once again – man’s interference with the natural order of things – almost led to my demise. Oh! the unimaginable loss.

Are Round and Long Lakes man-made?

My thanks in advance for your patience in taking the time to settle this issue for two soon-to-retire-in-Wooster Sylvania, Ohioans.
