Summary

2 is a privately owned irrigation dam located in Campbell, Wyoming, along Cottonwood Creek. Completed in 1961, this earth dam stands at a height of 14 feet and has a storage capacity of 147 acre-feet. With a spillway width of 30 feet and an uncontrolled spillway type, the dam poses a low hazard potential with a fair condition assessment.

Managed by the Wyoming State Engineer's Office, White No. 2 is subject to state regulations, permitting, inspection, and enforcement. The dam serves its primary purpose of irrigation, with a normal storage capacity of 57 acre-feet. Despite its moderate risk assessment, the dam's emergency action plan status and risk management measures remain unclear, highlighting areas for potential improvement to ensure the safety and integrity of the structure.

Located in the congressional district of Wyoming, White No. 2 plays a crucial role in water resource management and supports agricultural activities in the region. With a focus on sustainability and climate resilience, ongoing monitoring and maintenance efforts are essential to safeguarding the dam and its surrounding community from potential risks and impacts of changing environmental conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
