Stephany Dam, located in Woodbine, Iowa, serves multiple purposes including fire protection, stock, and small fish pond. Built in 1945, this private earth dam stands at 26 feet high and spans 250 feet in length, with a storage capacity of 191 acre-feet. Situated on the TR-Boyer River, this dam is regulated by the Iowa Department of Natural Resources and is subject to state permitting, inspection, and enforcement to ensure its safety and compliance with regulations.

The dam's low hazard potential and moderate risk assessment reflect its overall stable condition and the measures in place to manage any potential risks. While the dam's last inspection dates back to 1979, its risk management strategies and emergency action plans have not been rated or updated in recent years. Despite these gaps in assessment and preparedness, Stephany Dam continues to provide essential functions for the local community while being closely monitored for any necessary maintenance or improvements.

Although the dam has not undergone recent evaluations, its historical significance and vital role in water resource management warrant continued attention and oversight to ensure its continued safety and efficiency. With a focus on fire protection, livestock support, and recreational fishing opportunities, Stephany Dam remains an integral part of the environmental and agricultural landscape in Harrison County, Iowa.
