Dd No 2-30c, located in Brown County, Kansas, is a critical local government-owned earth dam constructed in 1980 for flood risk reduction along Roy's Creek-TR. With a height of 35 feet and a length of 725 feet, this dam provides a storage capacity of 99.5 acre-feet and a surface area of 4.8 acres. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition, with the last inspection conducted in August 2005.

Managed by the Kansas Department of Agriculture, Dd No 2-30c is state-regulated and permitted, inspected, and enforced for compliance with safety standards. The dam features an uncontrolled spillway with a width of 60 feet, providing an essential outlet for excess water during flood events. Although no emergency action plan (EAP) or inundation maps have been prepared, the dam is maintained at a low hazard potential level, ensuring the safety of surrounding communities in case of any unforeseen emergencies.

Overall, Dd No 2-30c serves as a vital infrastructure for flood risk reduction in the region, showcasing the importance of proper dam maintenance and monitoring to mitigate potential risks associated with extreme weather events. As climate change continues to impact water resources, the resilience of structures like Dd No 2-30c becomes increasingly crucial in safeguarding communities and ecosystems from the threats of flooding and water scarcity.
