Pender Dam, located in Martensdale, Iowa, on the TR-Clanton Creek, was completed in 1964 by the USDA NRCS. This earth dam stands at a height of 25 feet and spans 460 feet, creating a reservoir with a storage capacity of 33 acre-feet. The primary purpose of the dam is for fire protection, stock, or small fish pond usage, serving as a vital resource for the local community.

Managed by a private owner, Pender Dam is regulated by the Iowa Department of Natural Resources, with state jurisdiction, permitting, inspection, and enforcement in place. Despite a low hazard potential and a moderate risk assessment level, the condition of the dam is currently not rated, emphasizing the need for ongoing monitoring and maintenance to ensure its safety and functionality. With its uncontrolled spillway and soil foundation, Pender Dam remains a significant water resource in the region for both agricultural and recreational purposes.

For water resource and climate enthusiasts, Pender Dam presents a unique opportunity to study the intersection of infrastructure, environmental management, and community resilience. As a part of the Kansas City District, this dam serves as a reminder of the importance of sustainable water management practices in the face of changing climate patterns. With its historical significance and ongoing regulatory oversight, Pender Dam continues to be a focal point for understanding the interconnectedness of water resources and climate dynamics in the Midwest.
