Lidtke Mill Dam, located on the Upper Iowa River in Howard County, Iowa, was completed in 1860 and stands at a height of 12 feet with a length of 120 feet. The dam serves a primary purpose not specified in the data, but its low hazard potential and very high risk assessment rating make it a significant structure in terms of water resource management and climate resilience. The dam is state-regulated by the Iowa Department of Natural Resources, with permits, inspections, and enforcement in place to ensure its safety and compliance with regulations.

Despite its age, Lidtke Mill Dam remains a crucial part of the local water infrastructure, with a storage capacity of 198 acre-feet and a drainage area of 182 square miles. The dam's controlled spillway and other features indicate a level of sophistication in its design, making it an important asset for flood control and water supply management in the region. The dam's risk management measures and high-risk assessment underscore the need for ongoing monitoring and maintenance to protect against potential hazards and ensure its continued functionality in the face of changing climate conditions.

Overall, Lidtke Mill Dam stands as a testament to the historical importance of water infrastructure in the region and the ongoing challenges of managing these systems in the context of climate change. Its unique characteristics, state regulation, and risk assessment highlight the complex interplay between water resources, infrastructure, and climate resilience, making it a key site of interest for water resource and climate enthusiasts seeking to understand the impact of these factors on our built environment.
