The pond has a height of 13 feet and a length of 400 feet, with a storage capacity of 250 acre-feet and a drainage area of 6 square miles. The Otter Tail River feeds into the pond, which has a low hazard potential and is deemed to be in satisfactory condition as of its last assessment in 2009.

The structure is inspected every 8 years, with the last assessment taking place in August 2018. While the pond does not have an Emergency Action Plan (EAP) in place, it meets regulatory guidelines set by the state of Minnesota, as it is regulated, permitted, inspected, and enforced by the Minnesota Department of Natural Resources. With its peaceful surroundings and important role in water resource management, Lehmann Pond is a significant landmark for water resource and climate enthusiasts to explore and appreciate in the pristine wilderness of Minnesota.
