Located in La Valle, Wisconsin, the La Valle dam stands as a testament to early hydroelectric innovation, having been completed in 1850. This gravity dam on the Baraboo River serves multiple purposes, including hydroelectric power generation and recreation, with a storage capacity of 120 acre-feet and a drainage area of 233 square miles. The dam has a structural height of 12 feet and a hydraulic height of 10 feet, with a spillway designed for controlled water release.

Despite its age, the La Valle dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The risk assessment for this dam indicates a very high risk level, prompting the need for regular inspections every 10 years. While the dam has not been modified since 1941, it remains under state regulation and inspection by the Wisconsin Department of Natural Resources, ensuring its continued safe operation for both water resource management and recreational activities in the area.
