Frd No 30, also known as Elk River WS Joint District No 47, is a dam located in Howard, Kansas. Built in 1978 by the USDA NRCS, this earth dam stands at a height of 63 feet and serves the primary purpose of flood risk reduction along Rock Creek. With a storage capacity of 2897.74 acre-feet and a surface area of 29.15 acres, Frd No 30 plays a crucial role in managing water resources in the area.

Managed by the local government, Frd No 30 is regulated by the Kansas Department of Agriculture and undergoes state inspection, permitting, and enforcement. Despite being classified as having a low hazard potential, the dam's risk assessment is rated as moderate. The dam has not been assessed for its condition, but it meets the guidelines for emergency action plans. With its uncontrolled spillway and lack of outlet gates, Frd No 30 remains a key infrastructure for flood control in the region.

In the event of an emergency, the dam's emergency contacts are updated, and the risk management measures are in place to mitigate any potential risks. With its strategic location and design, Frd No 30 continues to be a vital asset for water resource management and climate resilience efforts in Elk County, Kansas.
