Summary
Built in 1966, this gravity dam serves as a Fish and Wildlife Pond, providing crucial habitat for local flora and fauna. With a height of 18 feet and a hydraulic height of 12 feet, Lucky Reservoir has a storage capacity of 220 acre-feet and a surface area of 220 acres.
Despite its low hazard potential and unlisted condition assessment, Lucky Reservoir plays a vital role in the region's water resource management. The dam is situated on the TRIB BIG LAKE stream, within the Portland District of the US Army Corps of Engineers. With its primary purpose being the preservation of fish and wildlife, Lucky Reservoir remains a key asset for conservation efforts in the area.
Even though Lucky Reservoir has not been rated for its condition, regular inspections are conducted every five years to ensure its structural integrity and safety. The dam has no associated locks and boasts a spillway width of 0 feet. Managed by the Bureau of Land Management, Lucky Reservoir is a testament to the importance of sustainable water resource management and environmental stewardship in the face of climate change challenges.

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.
