Webb Dam, located in Decatur County, Iowa, was completed in 1978 for fire protection, livestock, and small fish pond purposes. This earth dam stands at a height of 19 feet and spans 410 feet in length, providing a storage capacity of 52 acre-feet. The dam is regulated by the Iowa Department of Natural Resources and is subject to state permitting, inspection, and enforcement requirements. Despite its low hazard potential, the dam poses a moderate risk, prompting the need for risk management measures.

Managed by a private owner, Webb Dam is situated in the city of Lake La Shane along the TR-Lake La Shane river stream. The dam's design was overseen by the USDA NRCS, and it is only one of the associated structures in the area, with no federal agency ownership or funding attached to it. With a surface area of 3.1 acres and draining 0.26 square miles, the dam serves as a recreational spot in addition to its primary functions. While the dam has not been rated for its condition, it is crucial for enthusiasts and stakeholders to monitor its risk assessment and management strategies.

Despite its relatively low hazard potential, Webb Dam plays a vital role in providing essential services to the local community. With its strategic location and purposeful design, the dam serves as a valuable resource for fire protection, livestock, and recreational activities. As water resource and climate enthusiasts continue to monitor its risk assessment and management, Webb Dam stands as a testament to the importance of responsible dam ownership and maintenance in safeguarding water resources and enhancing environmental resilience.
