Frd No 37, also known as Elk River WS Dam 37, is a vital structure located in Elk Falls, Kansas, designed by the USDA NRCS to serve the primary purpose of flood risk reduction. Completed in 1973, this earth dam stands at a height of 52 feet and has a hydraulic height of 44 feet, with a length of 930 feet. It has a NID storage capacity of 669.74 acre-feet and a normal storage of 91 acre-feet, covering a surface area of 13.37 acres and draining an area of 2.17 square miles along the Elk River-TR.

Managed by the Kansas Department of Agriculture, Frd No 37 is state-regulated and inspected to ensure its structural integrity and functionality in flood control measures. With a low hazard potential and moderate risk assessment, this dam is a crucial component in the region's water resource management. Although its condition assessment is not rated, the dam's design and construction by the Natural Resources Conservation Service reflect a commitment to sustainable water infrastructure for the community.

For water resource and climate enthusiasts, Frd No 37 offers a fascinating insight into the intersection of engineering, environmental stewardship, and public safety. As part of the flood risk reduction system in Elk Falls, this dam plays a key role in protecting the surrounding area from potential inundation during periods of high water flow. Its controlled spillway, uncontrolled type, with a width of 40 feet, further enhances its capacity to manage excess water and minimize the risk of flooding downstream. With a history dating back to the early 1970s, Frd No 37 stands as a testament to the ongoing efforts to balance water resource utilization with environmental conservation in the region.
