Sensnovis, located in Sauk, Wisconsin, is a privately owned earth dam completed in 1973 with a primary purpose of fire protection, stock, or small fish pond. Managed by the USDA NRCS, this dam stands at 27 feet high with a hydraulic height of 19 feet, offering a storage capacity of 50 acre-feet and covering a surface area of 4 acres. It is situated on the Unnamed Tributary of Little Baraboo River.

Despite its low hazard potential and fair condition assessment, Sensnovis poses a very high risk due to its location and potential impact on the surrounding area. The dam has a controlled spillway type with a maximum discharge of 160 cubic feet per second. While it is state regulated and inspected by WIDNR, the last inspection took place in 2010, with a recommended frequency of every 10 years.

For water resource and climate enthusiasts, Sensnovis presents an opportunity to explore the intersection of private ownership, dam management, and environmental risk assessment. With its unique purpose and design, this dam serves as a focal point for understanding the delicate balance between water conservation, emergency preparedness, and regulatory enforcement in the context of changing climate patterns and evolving water resource management practices in Wisconsin.
