Summary
Completed in 1903, this Earth-type dam is primarily used for irrigation purposes along the Fourmile Creek. With a height of 22 feet and a storage capacity of 9950 acre-feet, it serves as a vital water resource for the region, supporting activities like fire protection, livestock watering, and small fish ponds.
Despite its age, Chimney Creek Dam has undergone modifications in 1999 to enhance its hydraulic and structural components. The dam's spillway, with a width of 4 feet, is uncontrolled, and its hazard potential is classified as low. However, an inspection in 2018 deemed its condition unsatisfactory, highlighting the need for ongoing maintenance and risk management measures to ensure its continued safety and functionality.
Managed by the Nevada Department of Water Resources, Chimney Creek Dam plays a crucial role in water management within the area. Its historical significance, combined with its practical utility, makes it a key feature for water resource and climate enthusiasts interested in the sustainable utilization and preservation of vital water infrastructure.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
