Gross Dam, located in Shelby County, Iowa, was completed in 1975 and serves multiple purposes including fire protection and small fish pond management. Owned privately, this earth dam stands at a height of 25 feet and stretches 580 feet in length, with a storage capacity of 43 acre-feet. The dam is regulated by the Iowa Department of Natural Resources and undergoes state inspections and enforcement to ensure its safety and compliance with regulations.

Situated on the TR-Mosquito Creek, Gross Dam poses a low hazard potential with a moderate risk assessment. Although its condition is not rated, the dam meets regulatory guidelines and its risk management measures are in place. Despite its uncontrolled spillway type, the dam's emergency action plan readiness and inundation maps preparation status remain unknown. With a surface area of 3 acres and a drainage area of 0.23 square miles, Gross Dam plays a crucial role in water resource management and climate protection in the region.

With its strategic location and design by USDA NRCS, Gross Dam not only provides essential water storage for fire protection and fish pond management but also contributes to the overall water resource management in the area. As climate change continues to impact water availability and quality, the proper maintenance and regulation of dams like Gross Dam are essential to ensure the safety and sustainability of water resources for both human and environmental needs.
