Lagrange Lake Dam, also known as Whitford Dam, is a private-owned structure located in LaGrange, Michigan. Built in 1826, this earth dam stands at a height of 15 feet and spans 500 feet in length, serving primarily for recreational purposes. Situated on Dowagiac Creek, the dam boasts a storage capacity of 4,800 acre-feet, with a significant hazard potential due to its controlled spillway and maximum discharge rate of 1,325 cubic feet per second.

Despite being non-regulated by the state, Lagrange Lake Dam presents a very high risk profile, as indicated by its risk assessment rating of 1. The dam's condition remains unrated, with the last inspection conducted in 2003. Although an emergency action plan was prepared in 2004, details regarding its adherence to guidelines and the existence of inundation maps are unclear. With its scenic location and ample surface area of 600 acres, Lagrange Lake Dam stands as a focal point for water resource and climate enthusiasts interested in the intersection of recreational infrastructure and risk management in Michigan's Cass County.
