Summary
Built in 1917 for irrigation purposes, this Earth-type dam stands at a height of 23 feet and has a storage capacity of 52 acre-feet. With a low hazard potential and moderate risk assessment, Lady Emma plays a crucial role in providing water for irrigation, fire protection, stock, and small fish ponds in the area.
Managed by the Wyoming State Engineer's Office, Lady Emma undergoes regular inspections and enforcement to ensure its structural integrity and safety. With a spillway width of 27 feet and a maximum discharge capacity of 906 cubic feet per second, the dam is equipped to handle potential flooding events. Despite its age, Lady Emma continues to serve the community effectively, highlighting the importance of proper maintenance and regulation for water resource management in the region.
As a significant piece of infrastructure in the Sacramento District, Lady Emma stands as a testament to early 20th-century engineering and the ongoing importance of water resource management in Wyoming. With its historical significance and functional role in providing essential water services, this dam serves as a reminder of the intricate relationship between human development, climate challenges, and sustainable water use practices.

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.
