Sulentic Dam, located in Council Bluffs, Iowa, is a private-owned structure designed by NRCS and completed in 2002 for flood risk reduction along the tributary to Twin Ponies. Standing at a height of 38 feet and a length of 570 feet, this earth dam serves as a crucial infrastructure to protect the surrounding area from potential flooding events. With a storage capacity of 25 acre-feet and a spillway width of 12 feet, Sulentic Dam plays a significant role in managing water flow and maintaining the stability of the region.

Despite its low hazard potential and moderate risk assessment, Sulentic Dam has not been rated for its condition assessment. It does not fall under state regulation or inspection, indicating the responsibility lies with the private owner for its operation and maintenance. The dam primarily serves for flood risk reduction and grade stabilization purposes, highlighting its importance in safeguarding the community against potential natural disasters. As a key structure in the area, Sulentic Dam stands as a testament to effective water resource management and climate resilience efforts within the region.

As an essential piece of infrastructure in Pottawattamie County, Sulentic Dam showcases the collaborative efforts between private ownership and design by NRCS to mitigate flood risks and ensure the safety of the surrounding residents. With its strategic location and design features, such as an uncontrolled spillway and stone core, the dam serves as a critical barrier against potential flooding events. While its condition assessment remains unrated, Sulentic Dam's role in flood risk reduction and grade stabilization underscores its significance in the overall water resource and climate management efforts in the region.
