Summary
Completed in 1970, this earth dam structure stands at 11 feet high and has a storage capacity of 968 acre-feet, with a normal storage level of 638 acre-feet. The reservoir covers an area of 110 acres and is fed by the South Fork of the Shoshone River.
The dam at Beck Lake has a spillway type of "Uncontrolled" with a width of 8 feet, and an outlet gate consisting of a single valve. The hazard potential of the dam is considered significant, with a fair condition assessment as of the last inspection in June 2019. Despite its moderate risk assessment, the reservoir serves as a critical water resource for the surrounding area and plays a vital role in supporting agricultural activities in the region.
With its strategic location and essential role in irrigation, Beck Lake serves as a crucial water source in the region. The reservoir's design and construction reflect a commitment to water management and agricultural sustainability. As climate change continues to impact water resources, Beck Lake remains a key asset in ensuring water availability for the community and supporting the local economy.

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.
