Dillon Dam, located in Summit County, Colorado, is a major earth dam completed in 1963 with a primary purpose of providing water supply. Standing at a height of 231 feet and a length of 4625 feet, this dam has a storage capacity of 305,000 acre-feet and covers a surface area of 3300 acres. Its maximum discharge capacity is 11,750 cubic feet per second, making it a crucial structure for managing water resources in the region.

Managed by the local government and regulated by the Colorado Division of Water Resources, Dillon Dam plays a vital role in supporting multiple purposes including hydroelectric power generation, recreation, and water supply. The dam's high hazard potential and moderate risk assessment highlight the importance of effective risk management measures. With inspections by the Federal Energy Regulatory Commission and emergency action plans in place, Dillon Dam remains a key infrastructure for water management in the area.

Situated on Blue Creek in Silverthorne, Dillon Dam not only serves as a key water supply source but also contributes to recreational activities and hydroelectric power generation. As climate change continues to impact water resources, the significance of structures like Dillon Dam in ensuring water security and resilience in the face of changing conditions becomes increasingly evident.
