Frd No 40 is a local government-owned earth dam located in Barnard, Kansas, specifically in Lincoln County. The dam, completed in 1984, serves primarily for flood risk reduction along the Prosser Creek-TR river/stream. With a height of 31 feet and a length of 950 feet, Frd No 40 has a storage capacity of 341.1 acre-feet, with a normal storage level of 52.4 acre-feet and a surface area of 10.1 acres.

Although classified as having a low hazard potential, Frd No 40 is regulated, permitted, inspected, and enforced by the Kansas Department of Agriculture. The dam features an uncontrolled spillway with a width of 40 feet, and it does not have outlet gates or associated structures. Despite being in operation for several decades, the dam's condition assessment is currently listed as "Not Rated," indicating a need for further evaluation to ensure its continued effectiveness in flood risk reduction.

For water resource and climate enthusiasts, Frd No 40 presents an interesting case study of a local government-owned earth dam designed by A&E and SCS engineers. The dam's location in a moderate risk area, as well as its historical and current maintenance status, make it a valuable asset to monitor in the context of climate change and increasing water variability. As efforts to address environmental challenges continue, Frd No 40 serves as a reminder of the importance of proactive management and maintenance of critical infrastructure to mitigate flood risks and ensure long-term water resource sustainability.
