Dane Ridge Watershed Site C-7 is a crucial water resource located in Crawford, Iowa, near the city of Dunlap. Managed by the local government and designed by the USDA NRCS, this earth dam was completed in 1977 for purposes including fire protection, stock, and small fish pond creation, as well as flood risk reduction. With a height of 38 feet and a length of 465 feet, the dam has a storage capacity of 262 acre-feet and serves a drainage area of 3.57 square miles, primarily affecting the TR-Boyer River.

Despite its low hazard potential and moderate risk assessment, Dane Ridge Watershed Site C-7 remains under the regulatory oversight of the Iowa DNR, with state permitting, inspection, and enforcement in place. The dam’s structure, primarily composed of soil, has not been rated for its condition, and there is limited information on emergency action plans or risk management measures. The surrounding area covers 15 acres, providing a vital water source for the community and supporting various ecological functions.

As water resource and climate enthusiasts, the Dane Ridge Watershed Site C-7 offers a fascinating case study for understanding the intersection of infrastructure, environmental conservation, and community resilience. With its historical significance dating back to the late 20th century, this dam continues to play a crucial role in managing water resources, mitigating flood risks, and supporting local ecosystems. Further research and monitoring of this site could provide valuable insights into sustainable water management practices and the potential impacts of climate change on dam safety and performance.
