Hamak is a state-regulated dam located in Faulk, South Dakota, along the Snake Creek Tributary. Built in 1938 by the Works Progress Administration (WPA), this earth dam stands at 28 feet high and stretches 400 feet in length, with a storage capacity of 490 acre-feet. The dam has a low hazard potential and has not been rated for its condition, but it is inspected every three years to ensure safety and compliance with state regulations.

Managed by the South Dakota Department of Agriculture and Natural Resources (DANR), Hamak serves as a vital structure for flood control and water resource management in the area. With a maximum discharge capacity of 1400 cubic feet per second and an uncontrolled spillway width of 50 feet, the dam plays a crucial role in mitigating potential flood risks to downstream communities. Despite its age, Hamak continues to serve its purpose effectively, highlighting the importance of maintaining and monitoring critical infrastructure in the face of changing climate conditions.

Overall, Hamak represents a significant piece of South Dakota's water resource infrastructure, providing essential services for both flood control and water supply. With its historical significance and continued functionality, the dam serves as a reminder of the importance of sustainable water management practices in the context of a changing climate. As climate enthusiasts and water resource stakeholders, it is crucial to monitor and support infrastructure like Hamak to ensure the resilience and sustainability of our water systems for future generations.
