Lang, also known as Lake of The Woods, is a privately owned dam located in Marquette, Wisconsin. Built in 1973, this gravity dam stands at a height of 11 feet and has a maximum storage capacity of 100 acre-feet. Its primary purpose is for recreation, with a normal storage capacity of 25 acre-feet and a surface area of 20 acres.

Managed by the Wisconsin Department of Natural Resources, Lang is regulated, permitted, and inspected by the state agency to ensure its safety and compliance with standards. With a controlled spillway and low hazard potential, this dam on Little Pine Creek presents a very high risk assessment rating of 1. Despite its risk level, Lang has not been rated for its current condition and has not been assessed for emergency action preparedness.

With its scenic location and recreational offerings, Lang serves as a vital water resource for the community while also posing potential risks that necessitate ongoing monitoring and maintenance to ensure the safety of both the dam and the surrounding area.
