Summary
Wolz. Completed in 1992, this earth dam serves primarily for irrigation purposes, with a storage capacity of 220 acre-feet and a surface area of 18 acres. The dam stands at 28 feet high, with a spillway width of 235 feet, and is regulated and inspected by the Wyoming State Engineer's Office.
Located along the Seventy Six Draw river, Glen Means has a low hazard potential and is in fair condition as of the last inspection in August 2018. Despite its moderate risk assessment, the dam meets regulatory guidelines and has emergency action plans in place. Managed by a private owner, this water resource plays a vital role in supporting agricultural activities in the area, contributing to the local water supply and ecosystem.
For water resource and climate enthusiasts, Glen Means represents a unique example of private water infrastructure in Wyoming, blending engineering innovation with environmental stewardship. Its presence underscores the importance of sustainable water management practices and the need for ongoing monitoring and maintenance to ensure the safety and reliability of our water resources in the face of changing climate conditions. With its picturesque location and crucial role in supporting local agriculture, Glen Means serves as a reminder of the interconnectedness of water, climate, and human activities in shaping our landscapes.

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.
