This earth dam, standing at a height of 26 feet and stretching 341 feet in length, serves multiple purposes including fire protection and as a small fish pond. With a storage capacity of 25 acre-feet and a surface area of 2.8 acres, the dam helps regulate the flow of TR-Alloway Creek.
Despite being classified as having a low hazard potential, Bagnall Dam poses a moderate risk due to its age and lack of recent inspections. The dam is maintained by the Iowa DNR and is subject to state regulations, inspections, and enforcement. With its uncontrolled spillway and soil foundation, the dam remains an important structure for water resource management in the region.
For water resource and climate enthusiasts, Bagnall Dam stands as a testament to the importance of maintaining and monitoring infrastructure to ensure public safety and environmental sustainability. As climate change continues to impact water resources, the role of dams like Bagnall in flood control and water supply management becomes increasingly vital. With proper oversight and maintenance, Bagnall Dam will continue to serve its purpose for years to come.
