Lowary Dam, located in Augusta, Iowa, is a privately owned earth dam designed by USDA NRCS and completed in 2008 for the primary purpose of grade stabilization. With a height of 26 feet and a length of 230 feet, the dam has a maximum storage capacity of 36 acre-feet and covers a surface area of 3 acres. Situated on a tributary to Cedar Creek, the dam plays a critical role in managing water resources in the region.

Despite being classified as a low hazard potential structure, Lowary Dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections, permitting, and enforcement to ensure its safety and compliance with state regulations. The dam has not been rated for condition assessment, but its design features stone core types and soil foundations. With a maximum discharge of 101 cubic feet per second, the dam serves as a vital infrastructure for water resource management in the area, contributing to flood control and water storage capabilities.

While Lowary Dam does not have a designated emergency action plan or inundation maps prepared, it continues to fulfill its role in grade stabilization and water management. With its strategic location and design features, the dam showcases the importance of private infrastructure in supporting sustainable water resource management and climate resilience efforts in the region.
