Located in Rock, Wisconsin, the Fulton dam on the Yahara River was completed in 1849 and serves primarily for recreational purposes. Standing at 16 feet tall with a hydraulic height of 9 feet, this gravity dam spans 800 feet and has a storage capacity of 350 acre-feet. With a drainage area of 553 square miles, the dam has a maximum discharge capacity of 9,600 cubic feet per second and a surface area of 49 acres.

Despite being rated as having low hazard potential and not currently assessed for condition, the Fulton dam poses a very high risk due to its age and limited inspection history. The last recorded inspection took place in August 1994, with an inspection frequency of 10 years. The dam has a controlled spillway type and is regulated by the Wisconsin Department of Natural Resources (WIDNR), with state jurisdiction, permitting, inspection, and enforcement in place.

Given the dam's historical significance and potential risk, enthusiasts of water resources and climate should be aware of the Fulton dam's condition and the need for regular monitoring and maintenance to ensure its continued safety and functionality. As a key landmark in the area, efforts to assess and mitigate risks associated with the dam are crucial to preserving the surrounding environment and protecting downstream communities from the potential impacts of dam failure.
