The Maarsee, which was originally around 128 m deep, has silted up over the millennia. It was only flooded again in 1942 by damming the Nollenbach stream. Today, sediment drillings provide scientists with information about the development of climate and vegetation in times long past. Today, the Jungferweiher is also an important bird sanctuary and is known for its abundance of migratory birds. Together with the Ulmener Maar, it is a nature reserve.
