Records of water levels on many Northwoods lakes often only go back a few decades, if they exist at all.

But one researcher has figured out a way to see the story of lakes going back hundreds of years.

That history, and a clue about the future, is as simple as tree rings themselves.

“We’re proposing using these trees as an Excel spreadsheet, as a way to get at [the history of] these lake levels,” said Dom Ciruzzi, a UW-Madison graduate student working at Trout Lake Station in Boulder Junction.
