Amstein, also known as Riverside Drainage District Dam 3of5, is a flood risk reduction structure located in Clay, Kansas. Built in 1953 by the USDA NRCS, this buttress dam stands at a height of 19 feet and has a hydraulic height of 16 feet. With a length of 670 feet and a storage capacity of 68 acre-feet, Amstein plays a crucial role in managing water flow along Mulberry Creek-TR.

Despite its low hazard potential and the absence of state regulation, Amstein serves as a vital infrastructure for flood control in the region. Operated by the local government, this dam has not been rated for its condition assessment and does not have an emergency action plan in place. As water resource and climate enthusiasts, understanding the significance of structures like Amstein in mitigating flood risks and safeguarding communities underscores the importance of sustainable water management practices in the face of changing climate patterns.
