Abell Dam, located in Union County, Iowa, is a privately owned earth dam completed in 1987 by the USDA NRCS. The dam serves multiple purposes, including fire protection and as a stock or small fish pond, with a normal storage capacity of 7 acre-feet. Situated on the TR-GRAND RIVER, the dam has a height of 32 feet and a length of 270 feet, with a low hazard potential and a moderate risk assessment rating.

Managed by the Iowa Department of Natural Resources, Abell Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. The dam's spillway is uncontrolled, and it has a surface area of 0.9 acres and a drainage area of 0.17 square miles. Despite not being rated for its condition, the dam is regularly monitored for any potential risks or issues that may arise, demonstrating a commitment to maintaining its integrity and safeguarding the surrounding area from flooding or other hazards.

For water resource and climate enthusiasts, Abell Dam presents a fascinating case study in dam engineering and management, highlighting the importance of balancing multiple uses and purposes while ensuring safety and regulatory compliance. Its location in a rural setting and its modest size make it a valuable asset for local fire protection and agricultural purposes, while also serving as a small habitat for fish and wildlife. As efforts continue to evaluate and mitigate potential risks associated with dams, Abell Dam stands as a testament to responsible stewardship and the essential role of water infrastructure in supporting communities and ecosystems.
