Summary
2, also known as Kirby Irrigation Co. #1, is a privately owned dam located in Torrington, Wyoming. This earth dam, completed in 1911, serves primarily for irrigation purposes, with a hydraulic height of 15 feet and a structural height of 20 feet. The dam has a storage capacity of 141 acre-feet, providing vital water resources for the surrounding area.
Situated on North Richard Creek, Grant No. 2 is regulated by the state of Wyoming, with permitting, inspection, and enforcement conducted by the State Engineer's Office. Despite being classified as having a low hazard potential, the dam's risk assessment is moderate (3), indicating a need for effective risk management measures. With a spillway width of 50 feet and one valve outlet gate, the dam's last inspection in May 2021 underscores the importance of regular monitoring and maintenance to ensure its continued safety and functionality in the face of changing climate conditions.
Overall, Grant No. 2 plays a crucial role in water resource management in the region, highlighting the intersection of infrastructure, climate resilience, and agricultural sustainability. As climate enthusiasts and water resource stakeholders continue to monitor and address the challenges posed by a changing environment, dams like Grant No. 2 serve as critical pieces of infrastructure that require ongoing attention to adapt and respond effectively to evolving climatic conditions.

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.
