Summary
Managed by the Bureau of Indian Affairs, this reservoir primarily serves the purpose of irrigation, with additional recreational uses. Constructed in 1938, it has a structural height of 45 feet and a storage capacity of 490 acre-feet, making it a vital water source for the surrounding area.
Situated along Quartz Creek, Happy Valley plays a crucial role in water management and provides essential irrigation support for the region. With a maximum discharge of 225 cubic feet per second and a high hazard potential, this reservoir requires regular inspections and monitoring to ensure its safety and functionality. Despite its age, the dam remains in good condition, meeting regulatory guidelines and serving as a key asset for water supply and agricultural needs in the area.
The risk assessment for Happy Valley indicates a very high risk level, emphasizing the importance of effective risk management measures and emergency preparedness. With the involvement of the Bureau of Indian Affairs in its operation, maintenance, and regulation, this reservoir continues to be a significant water resource for the local community, highlighting the intersection of water resource management, climate resilience, and safety in the face of potential hazards.

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.
