Newest reservoirs in Wisconsin
The year that a reservoir was first filled to the reservoir’s normal elevation – or the year that a natural lake was first dammed – is the determining factor in the age of the body of water. A large reservoir can take more than a year to fill after its dam is first closed. You can find many of the the world’s newest reservoirs on LakeLubbers in the comparison table below. Many of the world’s oldest reservoirs appear on the last page of that list. Note: For some lakes, the completion year data is unknown, so you may see fewer lakes than the total 128 articles we have published for Wisconsin lakes.Thinking about booking a Wisconsin lake vacation home rental, cabin or hotel?
