Summary
Completed in 1997, this earth dam stands at a height of 16 feet with a hydraulic height of 14 feet and a structural height of 40 feet. With a length of 1250 feet, it has a storage capacity of 25.5 acre-feet and covers a surface area of 2.1 acres. Despite having no spillway, the dam is classified as low hazard potential and in fair condition as of the last inspection in June 2019.
Located in Humboldt County, Nevada, this private dam falls under the jurisdiction of the Nevada Division of Water Resources. It is regulated, permitted, inspected, and enforced by state authorities, ensuring that it meets safety standards and poses minimal risk to the surrounding area. Although it has a high risk assessment rating, the Trenton Canyon Overflow Pond Dam remains well-managed and equipped to handle any emergencies that may arise, with a designated inspection frequency of 5 years.
Overall, the Trenton Canyon Overflow Pond Dam stands as a testament to efficient water resource management in Nevada, serving its intended purpose effectively while adhering to state regulations and safety protocols. For water resource and climate enthusiasts, this structure represents a vital component of the region's infrastructure, showcasing the importance of responsible dam construction and maintenance in mitigating risks and ensuring environmental sustainability.

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.
