K-7 is a vital structure located in Hiatville, Kansas, serving the primary purpose of debris control on the Bunion Creek-TR. Constructed in 2010 by AG Engineering, this earth dam stands at a height of 20.4 feet, with a hydraulic height of 17.4 feet and a structural height of 22.7 feet. The dam boasts a storage capacity of 338.24 acre-feet, with a normal storage level of 50.96 acre-feet, covering a surface area of 16.21 acres and draining a 1.19 square mile watershed.

Operated by the Kansas Department of Agriculture, K-7 is designed to mitigate flood risk and protect surrounding areas from inundation, featuring an uncontrolled spillway with a width of 80 feet. Despite being rated as having low hazard potential and moderate risk, the dam's condition remains unrated, with its last inspection conducted in September 2010. With state-regulated permitting, inspection, and enforcement in place, K-7 ensures the safety and sustainability of water resources in Bourbon County, Kansas.

As a crucial component of water resource management in the region, K-7 plays a critical role in controlling debris and safeguarding communities from potential flood events. With its earth dam structure and strategic location on Bunion Creek-TR, this dam exemplifies the collaboration between local government agencies and engineering firms in ensuring the resilience of water infrastructure in Kansas. With a focus on risk management and regulatory compliance, K-7 stands as a testament to the ongoing efforts to protect water resources and the environment in a changing climate landscape.
