Devil's Lake (Wisconsin)
Devil's Lake is a lake in the South Range of the Baraboo Range, about two miles south of Baraboo, Wisconsin, in Sauk County, Wisconsin, United States. It has no surface outlets, so by some definitions, it is endorheic; however, it possibly drains by underground channels into the Baraboo River, which would make the lake cryptorheic. The lake is one of the primary attractions of Devil's Lake State Park. It is also a popular recreation destination for watercraft, fishing, hiking, and climbing. Name
Devil's Lake was so named because it is situated in a deep chasm with no visible inlet or outlet. The term, Devil's Lake is a misinterpretation of the Ho-Chunk names Te Wakacakra or De Wakacak (Tawacunchukdah or Da-wa-kah-char-gra), which better translates to "Sacred Lake" or "Spirit Lake." Spirit Lake is highly significant in Ho-Chunk oral history, and voices of spirits were often claimed to be heard during the celebrations. History

The original inhabitants of the area around the lake date back much further than when the European settlers first discovered the land. There is proof that humans occupied the land between 12,000 to 16,000 years ago, but Ho-Chunk speak of people living there longer than 300,000 years ago. The area may have been inhabited originally between 12,000 to 16,000 years ago due to the fact that this was the time the last of the glaciers had receded from the area. Many Native tribes throughout Wisconsin inhabited the lands. They called the lake various different names, such as Tewakakak or Minnewaukan, which translate to spirit lake in various Native American Languages. Devil's Lake was originally a gorge of the Wisconsin River prior to the last ice age. At what is now the southern end of the lake, the river turned from a southerly direction to an easterly direction. During the ice age, a lobe of the glacier passed to the east of the Baraboo Hills and came up the river valley. It deposited materials and then melted, leaving a terminal moraine blocking the river, forming an earthen dam. Another moraine was deposited at the north end of the lake. The river eventually found a new course to the east of the Baraboo Hills, where the glacier had been, leaving a portion of the river gorge between the moraines filled with water. This body of water is Devil's Lake. Geology 
The Devil's Lake State Park is made up of bluffs that are believed to be one of the most ancient surface rock area in North America. Formed about 1.6 billion years ago, the land consists of Northern and Southern mountain ranges that are made up of quartzite rock. Quartzite was formed after ancient rivers deposited sediment from when this land was under water. Over time, that sediment accumulated into sandstone and underwent immense heat and pressure to form the non-porous metamorphic rock that now encompasses the Baraboo valley. The valley itself consists of softer rock as continental plate activity caused the quartzite rock to form into what's known now as the North and South range. Water temperature 
The water temperatures of Devils Lake varies significantly throughout a calendar year. The highest water temperatures are reported between July and August between 75 and 80 degrees Fahrenheit. The lowest water temperatures for the year are in January, with an average temperature of 35 degrees Fahrenheit. The lake freezes over in the winter, but ice thickness is unmeasured.
