Mountain Dell is a historic dam located in Salt Lake City, Utah, along the scenic Parleys Creek. Built in 1916, this buttress dam stands at a structural height of 105 feet and serves as a critical water supply source for the local government. With a storage capacity of 3,506 acre-feet, Mountain Dell plays a key role in providing water for the surrounding area.

Despite its importance, Mountain Dell is classified as having a high hazard potential and is currently rated in poor condition. The dam is regulated by the Utah Division of Water Rights, with regular inspections and enforcement measures in place to ensure its safety. The last inspection in May 2020 highlighted the need for improvements and maintenance to address the dam's deteriorating condition.

Enthusiasts of water resources and climate will find Mountain Dell to be a fascinating structure with a rich history and significant impact on the local ecosystem. As efforts continue to maintain and improve the dam's condition, it serves as a reminder of the importance of proper infrastructure management in ensuring the safety and sustainability of our water resources in the face of changing environmental conditions.
