Summary
Completed in 2020, these earth dams stand at a height of 29 feet with a hydraulic height of 26 feet, providing a storage capacity of 305 acre-feet. The ponds cover a surface area of 14 acres and have a normal storage capacity of 132 acre-feet.
Despite being classified as having a low hazard potential, the condition assessment of Hornbuckle Cofwd Ponds D & E is rated as "Fair," with the last inspection conducted in April 2021. The inspection frequency is set at 5 years, and the risk assessment has identified a high risk level (2) associated with these structures. While the spillway type is listed as "None," the presence of outlet gates is noted as "None," indicating a potentially unique design feature for managing water flow. Overall, these ponds play a vital role in water resource management in the area, serving both practical and regulatory purposes.
For water resource and climate enthusiasts, Hornbuckle Cofwd Ponds D & E offer a fascinating case study of privately owned earth dams in Wyoming that contribute to local water storage and management efforts. With their unique design and storage capacity, these structures stand as important components in the broader ecosystem and water infrastructure of the region. Monitoring and maintaining these ponds will be crucial to ensure their continued functionality and safety while addressing any potential risks identified in the periodic inspections and assessments.

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.
