The Kennecott Smelter Tailings Pond, located in Utah, is a privately-owned structure regulated by the Utah Division of Water Rights. This significant structure serves the primary purpose of storing tailings and is deemed to have a significant hazard potential. With a hydraulic height of 150 feet and a structural height of 154 feet, the pond has a storage capacity of 3000 acre-feet and drains offstream into the Jordan River.

Despite being an Earth-type dam with a length of 5800 feet, the Kennecott Smelter Tailings Pond lacks certain essential information such as dam volume and surface area. However, it undergoes regular state inspections, with the last inspection occurring in October 2020. The dam's condition is currently labeled as "Not Rated," and there is no available Emergency Action Plan (EAP) or risk assessment for the structure. With its location in the Salt Lake County draining to the Jordan River, enthusiasts of water resources and climate may find the Kennecott Smelter Tailings Pond an intriguing case study in environmental stewardship and risk management.
