Frd No W-3, also known as Fall River Watershed Dam W-3, is a key structure managed by the local government in Greenwood County, Kansas. Constructed in 1964 by the USDA NRCS, this earth dam stands at a height of 42 feet and serves the primary purpose of flood risk reduction along the West Branch Fall River. With a normal storage capacity of 55 acre-feet and a maximum storage of 1023.93 acre-feet, Frd No W-3 plays a crucial role in regulating water flow and protecting the surrounding area from potential flooding events.

Located in EUREKA, Kansas, Frd No W-3 is state-regulated and subject to inspection, permitting, and enforcement by the Kansas Department of Agriculture. Despite its low hazard potential, the dam is categorized as having a moderate risk level (3) and its condition is currently not rated. With a surface area of 10.9 acres and a drainage area of 2.3 square miles, this dam contributes to the overall water resource management efforts in the region and is an important asset in the flood risk reduction strategy for the local community.

Although Frd No W-3 has not undergone recent modifications or condition assessments, it remains a critical infrastructure for water resource and climate enthusiasts to monitor. With the potential to impact the surrounding area in the event of a breach or failure, the dam's risk management measures and emergency action plan (EAP) readiness are key factors to consider for ensuring the safety and protection of downstream communities. As part of the Kansas City District, this dam stands as a testament to the ongoing efforts to balance water resource management with environmental conservation and public safety.
