East Fork Grand River Watershed Site A-93, located in Ringgold County, Iowa, is a key flood risk reduction structure designed by the USDA NRCS and completed in 2008. This earth dam stands at a height of 23 feet, with a length of 612 feet, providing a storage capacity of 65 acre-feet for floodwaters. Despite its low hazard potential and moderate risk assessment, the dam is not currently rated for its condition and lacks a detailed emergency action plan.

Managed by the local government and regulated by the Iowa DNR, this site plays a crucial role in mitigating flood risks in the area and protecting the surrounding communities. With a drainage area of 0.19 square miles and a spillway width of 20 feet, the dam serves as a vital infrastructure for water resource management in the East Fork Grand River watershed. While there are no associated structures or outlet gates, the dam's primary purpose remains focused on flood risk reduction, aligning with its operational and regulatory requirements.

As water resource and climate enthusiasts explore the data for East Fork Grand River Watershed Site A-93, they will find a valuable example of dam infrastructure in the region. With its strategic location, design features, and regulatory oversight, this site showcases the collaborative efforts between federal agencies, state regulators, and local authorities to enhance water management practices. However, there is room for further assessment and planning to ensure the long-term resilience and effectiveness of this flood risk reduction structure in the face of changing climate patterns and increased water-related challenges.
