Completed in 1937, the concrete dam stands at a height of 16 feet with a hydraulic height of 9 feet and a length of 401 feet. It has a controlled spillway with a width of 367 feet and one lock measuring 144 feet in length and 35 feet in width.
A recent risk assessment conducted by USACE identified potential hazards such as overtopping of the island between the dam and navigation channel, as well as seepage through the abutments. To mitigate risks, regular inspections, maintenance, and emergency action plans are in place. The dam's partners work closely to monitor conditions, with USACE staff making frequent visits to adjust gates and ensure structural integrity. Additionally, proactive measures such as tree removal and equipment upgrades have enhanced the dam's reliability and long-term resilience.
For water resource and climate enthusiasts interested in the management of infrastructure like Menasha Lock and Dam, the collaboration between multiple agencies and the proactive approach to addressing potential risks serve as an example of effective risk management and maintenance practices in ensuring the safety and functionality of critical water resources.
