Schilling Dam, located in Lucas County, Iowa, is a privately owned structure designed by USDA NRCS to primarily serve as a fire protection reservoir and stock pond. Completed in 1965, this earth dam stands at a height of 32 feet and has a length of 330 feet, with a storage capacity of 27 acre-feet. Situated on TR-OTTER CREEK near RED ROCK RESERVOIR, the dam is regulated by the Iowa Department of Natural Resources and is subject to state permitting, inspection, and enforcement.

The dam's low hazard potential and moderate risk assessment make it a crucial feature for water resource management in the region. While the dam has not been rated for its condition, it is essential for maintaining water supply and protecting against potential emergencies. Despite its relatively small surface area of 3 acres, the dam plays a vital role in mitigating risks and ensuring water availability for fire protection and livestock use.

With its uncontrolled spillway type and soil foundation, Schilling Dam exemplifies the importance of private infrastructure in supporting local water resources. As a key component of the regional water management system, the dam's significance extends beyond its immediate surroundings, contributing to the resilience of the water supply in Lucas County. For water resource and climate enthusiasts, Schilling Dam serves as a fascinating example of the intersection between private ownership, public regulation, and environmental stewardship in ensuring water security in the face of changing climate conditions.
