Valmy Dam Evaporation Pond E, located in Nevada's Humboldt County, serves as a crucial water resource management structure along the Humboldt River. This earth dam, with a height of 10 feet and a length of 4345 feet, was completed in 1980 and has a storage capacity of 270 acre-feet. Despite its low hazard potential, the dam's condition assessment is poor, highlighting the need for maintenance and improvement to ensure its long-term viability.

Managed by the Nevada Division of Water Resources, Valmy Dam Evaporation Pond E primarily serves an evaporation pond function, contributing to the management of water resources in the region. With a surface area of 27.1 acres and a normal storage capacity of 185 acre-feet, the dam plays a vital role in water storage and regulation for the surrounding area. However, the dam's risk assessment indicates a high level of risk, underscoring the importance of implementing effective risk management measures to mitigate potential hazards.

Despite its essential role in water resource management, Valmy Dam Evaporation Pond E faces challenges such as poor condition assessment and high risk potential. As a public utility structure regulated by the state of Nevada, ongoing inspection and maintenance are crucial to ensure the dam's safety and functionality. With its strategic location along the Humboldt River, this dam serves as a key component of the region's water infrastructure, highlighting the importance of proactive measures to address its current condition and enhance its long-term effectiveness in managing water resources and climate-related challenges.
