Steinbeck Dam, located in Marengo, Iowa, along the TR-Iowa River, serves as a vital resource for fire protection, stock, and small fish pond purposes. Constructed in 1989, this earth dam stands at a height of 28 feet and stretches 326 feet in length, with a storage capacity of 55 acre-feet. The dam also boasts a surface area of 4.3 acres and a drainage area of 0.09 square miles, making it a key component in water management and conservation efforts in the region.

Managed by a private entity, Steinbeck Dam falls under the jurisdiction of the Iowa Department of Natural Resources and is subject to state regulations, inspections, and enforcement. Despite its low hazard potential and moderate risk assessment, the dam's condition remains unrated, with no recent inspection data available. While it lacks certain features such as outlet gates and spillways, the dam continues to play a crucial role in maintaining water resources and safeguarding against potential emergencies in the area.

The Steinbeck Dam not only serves as a functional structure for water management but also contributes to the overall ecological balance of its surroundings. With its strategic location and purposeful design, this dam stands as a testament to sustainable water resource management practices and the importance of private-public partnerships in safeguarding our environment for future generations.
