Weimann Dam, located in Audubon, Iowa, is a privately owned structure with a primary purpose of fire protection and serving as a stock or small fish pond. Built in 1980 by the Soil Conservation Service (SCS), this earthen dam stands at a height of 31 feet and stretches 475 feet in length, with a storage capacity of 77 acre-feet. The dam is situated on the TR- EAST NISHNABOTNA RIVER, under the jurisdiction of the Iowa Department of Natural Resources (DNR) and is regulated, permitted, inspected, and enforced by state authorities.

The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While the risk assessment for the dam is moderate, management measures have not been specified. The surrounding area has a drainage area of 0.2 square miles and a surface area of 4 acres. With its uncontrolled spillway type and no outlet gates, the dam poses minimal risk to downstream communities. Despite its condition assessment status, the dam has not been reviewed for its emergency action plan or inundation maps, indicating a need for further assessment and preparedness in case of emergencies.

Water resource and climate enthusiasts will find Weimann Dam to be an interesting case study in private dam ownership and management. With its unique purpose, location, and design characteristics, the dam serves as a reminder of the importance of regular inspection, maintenance, and emergency preparedness for ensuring the safety and sustainability of water infrastructure in the face of changing climate conditions.
