Chimney Dam, located in Humboldt, Nevada, along the Little Humboldt River, stands as a testament to engineering excellence. Built in 1974 by the renowned firm MCCARTER & TULLER INC., this earth dam serves multiple purposes, including irrigation and recreation. With a height of 72 feet and a length of 1110 feet, the dam provides a storage capacity of 66,000 acre-feet and covers a surface area of 2080 acres.

Despite its impressive engineering feats, Chimney Dam currently faces significant hazard potential and poor condition assessment. The last inspection in September 2020 highlighted the need for improvements and maintenance to ensure the safety of the surrounding area. With a moderate risk assessment rating of 3, the dam's emergency action plan and risk management measures require attention and revision to meet guidelines and mitigate potential risks.

As water resource and climate enthusiasts, the story of Chimney Dam serves as a reminder of the delicate balance between human intervention and nature's forces. The dam's critical role in irrigation and recreation underscores the importance of proper maintenance and risk management to safeguard not only the structure but also the communities downstream. As discussions around water resource management and climate resilience continue, Chimney Dam stands as a case study in the ongoing effort to balance human needs with environmental stewardship.
