Summary
Built in 1947, this earth dam stands at a height of 45.9 feet and has a storage capacity of 700 acre-feet. Situated along the Malad River and Bear River, it serves multiple purposes, including flood control and irrigation for the surrounding area. With a significant hazard potential and fair condition assessment, the dam is regularly inspected and maintained by the Idaho Department of Water Resources to ensure its structural integrity and safety.
Managed by the Sacramento District of the US Army Corps of Engineers, Samaria No 2 Upper plays a crucial role in regulating water flow and providing essential resources for the local community. The dam's uncontrolled spillway and moderate risk assessment highlight the importance of proper monitoring and emergency preparedness measures. Its location in a high-risk area underscores the need for continued attention to its maintenance and risk management to prevent potential disasters and safeguard the region's water resources and climate resilience.
As a key component of the water infrastructure in the area, Samaria No 2 Upper serves as a vital link in the water supply chain, supporting agricultural activities and environmental sustainability. With its historical significance and ongoing regulatory oversight by the Idaho Department of Water Resources, the dam represents a critical piece of the region's water resource management strategy. By maintaining a proactive approach to risk assessment and emergency response planning, stakeholders can ensure the long-term viability of this essential water resource infrastructure for future generations of water resource and climate enthusiasts.

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.
