Jenkins Dam, located in Marion, Iowa, was completed in 1963 by the USDA NRCS and serves primarily for fire protection, stock, or as a small fish pond. The earth dam stands at 27 feet high and spans 379 feet, with a storage capacity of 60 acre-feet and a surface area of 3.2 acres. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition, and its last inspection dates back to 1967.

Managed by a private owner, Jenkins Dam is regulated by the Iowa DNR and falls under state jurisdiction, with permitting, inspections, and enforcement carried out by state agencies. The dam, situated along the TR-TRACY CREEK river/stream, plays a crucial role in water resource management and conservation efforts in the region. While its spillway is uncontrolled and there are no outlet gates, the dam serves as a vital asset for the local community and surrounding areas for various purposes.

Water resource and climate enthusiasts will appreciate the historical significance and structural details of Jenkins Dam, which continues to play a key role in the region's water management infrastructure. With its unique design and purpose, the dam stands as a testament to the importance of sustainable water resource practices and the collaboration between public and private entities in safeguarding against potential risks and ensuring the safety and well-being of local communities.
