Summary

Completed in 2019, this dam stands at a height of 17.5 feet with a hydraulic height of 20.5 feet, providing a storage capacity of 62.6 acre-feet for floodwaters. The dam's primary purpose is flood risk reduction, serving as a crucial infrastructure to protect the surrounding area from potential inundation.

With a spillway width of 200 feet and a maximum discharge capacity of 16 cubic feet per second, Blue Diamond Business Center Detention Basin Dam #1 is equipped to handle high hazard potential events while maintaining a fair condition assessment as of May 2021. The dam's emergency action plan status and risk assessment indicate moderate risk levels, highlighting the importance of ongoing monitoring and maintenance to ensure the safety and effectiveness of this critical water resource infrastructure. As a key component in the flood control system of Clark County, this dam plays a vital role in safeguarding the community against the impacts of extreme weather events and climate variability.

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.
