Summary
The dam, constructed primarily of earth with a stone core and soil foundation, stands at a height of 12 feet and has a hydraulic height of 10 feet. It spans a length of 700 feet and has a storage capacity of 12 acre-feet, with a surface area of 4.8 acres and a drainage area of 5.3 square miles. The dam is situated on Red Rock Creek and is regulated by the Nevada Division of Water Resources, with state jurisdiction, permitting, inspection, and enforcement in place.
Despite its significant hazard potential and poor condition assessment, Rancho Haven #2 Dam plays a crucial role in providing irrigation water to the surrounding area. The dam also supports recreational activities in the region. With a spillway width of 10 feet and a maximum discharge of 10 cubic feet per second, the dam has an uncontrolled spillway type. The structure is equipped with a single valve outlet gate and undergoes inspections every three years to ensure its safety and functionality.
Although the dam's risk assessment is categorized as moderate, efforts to enhance risk management measures and emergency action planning may be necessary to address potential safety concerns. With its unique design features and essential role in water resource management, Rancho Haven #2 Dam serves as a focal point for water resource and climate enthusiasts interested in understanding the intersection of infrastructure, regulation, and environmental stewardship in the region.

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.
