Troublesome Cr Watershed Site 45, located in Audubon, Iowa, is a crucial water resource managed by the local government and the Iowa Department of Natural Resources. This site, designed by USDA NRCS, serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. Completed in 1985, the earth dam stands at a height of 27 feet and stretches 530 feet in length, with a storage capacity of 114 acre-feet.

Despite its low hazard potential, the site has a moderate risk assessment due to its location along Troublesome Creek. The dam has not been rated for condition assessment, and emergency preparedness measures have not been fully developed. With a drainage area of 0.3 square miles and a surface area of 4.7 acres, this watershed site plays a critical role in managing water resources and mitigating flood risks in the region. Climate and water resource enthusiasts would find Troublesome Cr Watershed Site 45 an intriguing case study for its multi-functional design and regulatory oversight.
