Summary
This privately owned earth dam stands at a height of 43 feet with a hydraulic height of 30 feet, providing a maximum storage capacity of 750 acre-feet. With a significant hazard potential and poor condition assessment, the dam is in need of regular inspection and maintenance to ensure its structural integrity and safety.
Despite its poor condition, Wall Creek Dam Lower plays a crucial role in water resource management in the region, with a normal storage capacity of 400 acre-feet and a drainage area of 154 square miles. The dam features a controlled spillway with a width of 40 feet and multiple outlet gates for controlled water release. The risk assessment for the dam is categorized as very high, emphasizing the importance of implementing effective risk management measures to mitigate potential hazards and ensure the safety of surrounding communities.
With the dam being regulated by the Nevada Department of Water Resources and subject to regular inspections, it is essential for stakeholders to work together to address the structural deficiencies and improve the overall condition of Wall Creek Dam Lower. By prioritizing maintenance and implementing necessary repairs, the dam can continue to support irrigation activities and water resource management while safeguarding against potential risks associated with its current condition.

Dam Data Reference
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.
