Summary
2 is a privately owned Earth dam located in Natrona, Wyoming, along the Shalerock Draw river. Built in 1909 for irrigation purposes, this dam stands at a height of 15 feet with a hydraulic height of 10 feet and a structural height of 16 feet. It has a length of 3362 feet and a storage capacity of 1451 acre-feet, making it a crucial water resource for the area.
Despite its important function, Reynolds No. 2 is currently in poor condition, with a low hazard potential but a high risk assessment rating of 2. The dam has not been inspected since November 2017, and its emergency action plan and risk management measures are not up to date. With its outdated infrastructure and lack of maintenance, there is a pressing need for attention and potential rehabilitation to ensure the safety and functionality of this vital water resource.
As climate change continues to impact water resources and infrastructure, the importance of maintaining and upgrading structures like Reynolds No. 2 becomes increasingly evident. With proper inspection, maintenance, and potential improvements, this dam can continue to serve the community for irrigation and water storage while mitigating risks and ensuring resilience in the face of a changing climate.

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.
