Summary
2, also known as Enl. 2202r or Dipper No. 2, is a privately-owned structure located in Saratoga, Wyoming along the South Brush Creek. Built in 1953, this earth dam stands at a height of 10 feet and has a hydraulic height of 5 feet, primarily serving the purpose of irrigation. Despite its low hazard potential, the dam's condition assessment is rated as poor, indicating the need for maintenance and improvements to ensure its long-term safety and effectiveness.
With a normal storage capacity of 296 acre-feet and a maximum storage of 383 acre-feet, Wiant Dam No. 2 covers a surface area of 28 acres and spans a length of 123 feet. The dam lacks a spillway, relying on a single valve for outlet control. Despite being regulated and inspected by the State of Wyoming, the dam's risk assessment is rated as high, emphasizing the importance of implementing proper risk management measures to mitigate potential threats and ensure the safety of surrounding communities and ecosystems.
As climate change continues to impact water resources and infrastructure, the management and maintenance of dams like Wiant Dam No. 2 become increasingly critical. With its location in a region vulnerable to changing precipitation patterns and extreme weather events, this dam serves as a vital component of the local water supply system, highlighting the importance of proactive monitoring, maintenance, and risk mitigation strategies to safeguard against potential hazards in the face of a changing climate.

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.
