Summary

2, also known as Valley Reservoir, is a privately owned water storage facility located in Laramie, Wyoming. This reservoir, completed in 1909, serves primarily for irrigation purposes along Lone Tree Creek offstream. With a capacity of 230 acre-feet, it provides a vital water source for agricultural activities in the region.

Despite its historical significance, Gleason Reservoir No. 2 is facing some challenges in terms of its condition assessment. The dam is classified as having a poor condition, with a low hazard potential, and last inspected in September 2017. The reservoir's emergency action plan and risk management measures are also not clearly outlined, indicating a need for further evaluation and potential improvements to ensure the safety and reliability of the structure.

For water resource and climate enthusiasts, Gleason Reservoir No. 2 serves as a reminder of the importance of maintaining and monitoring aging infrastructure to ensure water security and resilience in the face of changing environmental conditions. As climate change continues to impact water resources, it is crucial to address the vulnerabilities of such structures and implement proactive measures to safeguard against potential risks and ensure sustainable water management for the future.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
