Summary
E. Lissolo Irrigation, located in the Skull Creek Oil Field in Weston, Wyoming, is a privately owned irrigation structure that plays a crucial role in water resource management in the area. Completed in 1955, this earth dam stands at a height of 30 feet and has a storage capacity of 89 acre-feet, making it a significant asset for agricultural activities in the region. Despite its age, the dam is still in operation and is regulated, inspected, and enforced by the State of Wyoming, ensuring its continued functionality and safety.
The dam's primary purpose is irrigation, with a spillway width of 85 feet and an outlet gate for controlled water release. While the structure has a low hazard potential, its condition assessment in 2017 revealed a poor state, indicating the need for maintenance and potential upgrades to ensure its long-term reliability. With a moderate risk level assigned and a regular inspection frequency of 5 years, V. E. Lissolo Irrigation remains a vital component of the water infrastructure in the area, serving the needs of local farmers and contributing to the overall water resource management efforts in Wyoming.
As water resource and climate enthusiasts, understanding and monitoring the condition of structures like V. E. Lissolo Irrigation is crucial for ensuring sustainable water use and resilience to future climate challenges. By staying informed about the state of irrigation infrastructure and advocating for necessary maintenance and improvements, enthusiasts can contribute to the efficient and effective management of water resources in Wyoming and beyond.

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.
