Lost Lake Dike, located in Wasatch, Utah, is a Federal-owned earth dam on the Upper Provo River, managed by the Bureau of Reclamation since its completion in 1931. Standing at a height of 23 feet, it serves as a vital water resource structure with a storage capacity of 1350 acre-feet. Despite its low hazard potential, the dam has not undergone recent condition assessments, making its current state unknown.

With no state jurisdiction or regulation, Lost Lake Dike is primarily overseen by the Bureau of Reclamation for operations, inspections, and regulatory purposes. The dam's Emergency Action Plan (EAP) status and risk assessment details are not readily available, raising concerns about emergency preparedness and management in case of potential hazards. Although the dam has a history of low risk, the lack of recent assessments and inspection updates underscores the importance of ongoing monitoring and maintenance to ensure its continued safety and functionality for water resource and climate enthusiasts in the area.
