Summary
Completed in 1974, this Earth dam stands at 20 feet high with a hydraulic height of 16.5 feet, serving various purposes including flood control and irrigation. With a storage capacity of 120 acre-feet and a drainage area of 0.5 square miles, Lamb-Weston plays a significant role in water storage and management in the region.
Despite being categorized as having a low hazard potential and fair condition assessment, Lamb-Weston is considered to have a very high risk level, indicating the importance of regular inspections and maintenance. The dam features a controlled spillway and has a maximum discharge capacity of 50 cubic feet per second. Its location in Power County, Idaho, highlights its strategic position in the water infrastructure network of the region. With state regulation and oversight by the Idaho Department of Water Resources, Lamb-Weston continues to play a vital role in water resource management in Idaho.
Managed by private owners, Lamb-Weston serves as a key component of the water resource infrastructure in Idaho, contributing to the efficient utilization of the Snake River's water resources. Its stone core and rock-soil foundation ensure its structural integrity, while its 550-foot length and 15-acre surface area reflect its significance in water storage and management. As climate change impacts water resources, structures like Lamb-Weston become increasingly essential for ensuring water security and resilience in the face of changing environmental conditions.

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.
