Completed in 1969, this earth dam serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. The dam has a height of 49 feet, a length of 436 feet, and a storage capacity of 192 acre-feet, with a normal storage level of 88 acre-feet.
Located in Sioux City along TR-Broken Kettle Creek, this dam has a low hazard potential and a moderate risk assessment score of 3. While the condition assessment is currently not rated, the dam has not undergone any modifications since its construction. The spillway type is uncontrolled, indicating that water flow is not regulated, and the dam is primarily used for managing water levels and protecting against potential floods. Despite being last inspected in 1994, the West Sunnyside Watershed Site C-1-2 remains an important piece of infrastructure for water resource management in the area.
