Karsten No. 1, located in Dodge, Wisconsin, is a gravity dam with a primary purpose of recreation. Built in 1971 by the USDA NRCS, this dam stands at a height of 18 feet and has a capacity to store 86 acre-feet of water. With a fair condition assessment as of May 2020, this dam has a low hazard potential but is still considered to have a very high risk due to its location on the TR-HORICON MARSH river or stream.

Managed by the Wisconsin Department of Natural Resources, Karsten No. 1 is subject to state regulations, inspections, and enforcement to ensure its safety and functionality. While it has not undergone any modifications since completion, the dam has a controlled spillway and a maximum discharge capacity of 70 cubic feet per second. Despite its recreational purpose, the dam's risk assessment remains a top priority for water resource and climate enthusiasts in the area.

Overall, Karsten No. 1 serves as a crucial structure for both water management and recreation in Wisconsin. Its unique design and historical significance make it a key point of interest for those interested in the intersection of water resources and climate change adaptation.
