Swanson Dam, located in Red Rock Reservoir, Iowa, is a privately owned structure designed by USDA NRCS for fire protection, stock, or small fish pond purposes. Completed in 1969, this earth dam stands at a height of 37 feet with a length of 533 feet, providing a storage capacity of 59 acre-feet and covering a surface area of 4 acres.

With a responsible emergency action plan and regular maintenance, this dam continues to fulfill its primary purposes effectively while ensuring the sustainable use of water resources in the area.
