Built in 1933, this gravity dam serves primarily for recreational purposes, offering a surface area of 28 acres and a maximum storage capacity of 160 acre-feet. With a height of 17 feet and a hydraulic height of 11 feet, Hebron has a controlled spillway that is 65 feet wide, capable of handling a maximum discharge of 1520 cubic feet per second. Despite its age, the dam's hazard potential is rated as high, with a very high risk assessment due to its condition being not rated.
Managed by the Wisconsin Department of Natural Resources (WIDNR), Hebron is subject to state regulation, permitting, inspection, and enforcement. While the dam has not been assessed for its current condition, it is inspected biennially as a precautionary measure. The surrounding area has a drainage area of 163.5 square miles, making Hebron an important structure in managing water resources in the region. Its location within Congressional District 05 of Wisconsin adds to its significance in the local water infrastructure.
For water resource and climate enthusiasts, Hebron offers a unique opportunity to explore the intersection of human-made structures and natural ecosystems. Its historical significance, ongoing regulatory oversight, and high hazard potential make it a focal point for understanding the challenges and importance of managing water resources in a changing climate. As efforts to address aging infrastructure and enhance resilience continue, Hebron remains a valuable case study for studying the complex relationship between dams, rivers, and environmental stewardship.
