Frd No 7, also known as the City of Atchison Dam 7, is a local government-owned structure located in Atchison, Kansas. Built in 1963 by the USDA NRCS, this earth dam serves the primary purpose of flood risk reduction along the White Clay Creek-TR. With a height of 52 feet and a length of 1120 feet, Frd No 7 has a maximum storage capacity of 975 acre-feet and a normal storage capacity of 206 acre-feet, covering a surface area of 18.1 acres and draining an area of 0.85 square miles.
The dam, classified as a buttress earth type, stands at a structural height of 58 feet and has a high hazard potential, yet its condition assessment remains satisfactory. Despite being regulated and inspected by the Kansas Department of Agriculture, with state permitting and enforcement in place, Frd No 7 has not undergone recent modifications or been assigned a Dam Safety Action Classification. The dam's emergency action plan status, risk assessment, and risk management measures are all currently undisclosed, highlighting potential areas for further study and evaluation in terms of its overall safety and resilience.
With its location in a highly populated area and its critical role in flood risk reduction, Frd No 7 presents an important case study for water resource and climate enthusiasts. As an integral part of the local infrastructure, the dam's condition, regulatory oversight, and emergency preparedness are key factors in ensuring the safety and protection of the surrounding community in the face of potential natural disasters and changing climate conditions.
