Summary

Standing at a height of 27 feet and with a length of 940 feet, this dam serves a primary purpose of 'Other' and has a storage capacity of 27.3 acre-feet. The dam is regulated by the Nevada Department of Water Resources and undergoes regular inspections, with the last assessment conducted in June 2019, revealing a fair condition.

Despite its fair condition, Brimstone Leach Event Pond Dam poses a significant hazard potential, with a high risk assessment rating of 2. It is equipped with one other controlled outlet gate and has a drainage area of 0.4 square miles. The dam does not have a spillway and is located in an area with no river or stream nearby. The Congressional District 02 representative for Nevada is Mark E. Amodei, and the dam falls under the jurisdiction of the Sacramento District of the US Army Corps of Engineers.

Water resource and climate enthusiasts would find Brimstone Leach Event Pond Dam intriguing due to its unique design, purpose, and regulatory oversight. With its high hazard potential and risk assessment, the dam's role in water management and potential impact on the surrounding environment make it a subject of interest for those passionate about sustainable water resource management and climate resilience.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
