Eldorado Canyon Dam, located in Lyon, Nevada, serves as a vital infrastructure for irrigation and water supply in the region. The dam, primarily constructed for agricultural purposes, stands at a height of 60 feet with a hydraulic height of 55 feet, utilizing earth and stone as core types and foundations. With a storage capacity of 570 acre-feet and a normal storage of 230 acre-feet, the dam plays a crucial role in water management for Eldorado Canyon Creek, covering a surface area of 25 acres and serving a drainage area of 53 square miles.

Despite its importance, Eldorado Canyon Dam is marked by high hazard potential and poor condition assessment, underscoring the need for regular inspections and maintenance. The dam features an uncontrolled spillway with a width of 50 feet and a single slide (sluice gate) outlet gate. However, the risk assessment for the dam is moderate, rated at 3, prompting the implementation of risk management measures to ensure the safety and stability of the structure. With the last inspection conducted in June 2021 and a frequency of one inspection per year, the dam's regulatory oversight falls under the purview of the Nevada Division of Water Resources.

As water resource and climate enthusiasts, the state of Eldorado Canyon Dam offers a compelling case study on the intersection of infrastructure, water management, and environmental stewardship. By understanding the complexities and challenges faced by this essential water system, stakeholders can work towards sustainable solutions that balance the needs of agriculture, the community, and the natural environment. As we navigate the impacts of climate change and increasing water demands, the story of Eldorado Canyon Dam serves as a reminder of the critical role that these structures play in shaping our water future and the importance of proactive risk management to ensure their long-term resilience.
