Pilot Knob Lake Dam, located in Fertile, Iowa, along the TR-WINNEBAGO RIVER, stands as a testament to conservation efforts in the state. Built in 1972 by the Iowa Conservation Commission, this earth dam spans 210 feet in length and reaches a height of 18 feet. Primarily serving as a recreational site, the dam offers a surface area of 24 acres for outdoor enthusiasts to enjoy.

With a storage capacity of 111 acre-feet, the dam provides essential water resources for the surrounding area while also maintaining a low hazard potential. Regular inspections by the Iowa Department of Natural Resources ensure the structural integrity of the dam, with the most recent assessment in June 2019 rating its condition as satisfactory. Despite moderate risk factors, the dam continues to meet regulatory guidelines and serve as a vital piece of infrastructure in the region.

For water resource and climate enthusiasts, Pilot Knob Lake Dam represents a harmonious blend of conservation and recreation. Its presence on the TR-WINNEBAGO RIVER not only enhances the natural landscape but also highlights the importance of sustainable water management practices. As a state-regulated and state-permitted structure, the dam serves as a model for responsible dam construction and maintenance, contributing to the overall well-being of the local ecosystem and community.
