Friesen Dam 1673, located in Hamilton County, Nebraska, is a local government-owned structure designed by the USDA NRCS to serve as a vital component in flood risk reduction along the TR-W FK Big Blue River. Completed in 1979, this earth dam stands at a height of 32 feet with a hydraulic height of 30 feet and a structural height of 40 feet, providing a storage capacity of 1170 acre-feet to mitigate potential flooding in the area. With a low hazard potential and satisfactory condition assessment as of June 2017, Friesen Dam 1673 plays a crucial role in safeguarding the surrounding communities from the impacts of extreme weather events.

The dam's primary purpose is flood risk reduction, aligning with its primary dam type of earth construction with a stone core and soil foundation. With a normal storage capacity of 80 acre-feet and a drainage area of 3.6 square miles, Friesen Dam 1673 has a maximum discharge capability of 1583 cubic feet per second, ensuring efficient water management during peak flow periods. Despite its low hazard potential, the dam undergoes regular inspections every five years and is regulated, permitted, inspected, and enforced by the Nebraska Department of Natural Resources to maintain its operational effectiveness and structural integrity.

Friesen Dam 1673's strategic location and design make it a critical infrastructure for water resource and climate enthusiasts, showcasing the intersection of engineering innovation and environmental stewardship in managing water resources. As part of the broader flood risk reduction strategy in Nebraska, this dam serves as a testament to collaborative efforts between local government agencies and the USDA NRCS to enhance the resilience of communities against the increasing threats of climate change and extreme weather events.
