Summary

2 is a privately owned earth dam located in Johnson, Wyoming, along the Sand Draw river. Built in 1973 by designer Clifford J. Sanders, this dam serves primarily for irrigation purposes, with a storage capacity of 243 acre-feet. With a structural height of 53 feet and a spillway width of 40 feet, the dam has a low hazard potential and is classified in fair condition as of the last inspection in April 2019.

Despite its relatively small surface area of 12 acres, Ridge Place No. 2 plays a crucial role in providing water for irrigation and other uses in the area. The dam is regulated by the State of Wyoming, with permitting, inspection, and enforcement processes in place to ensure its safety and functionality. The risk assessment for this dam is moderate, indicating a need for continued monitoring and potential management measures to mitigate any potential risks.

Located in a remote area with no associated structures or nearby city, Ridge Place No. 2 stands as a testament to the importance of water resource management in maintaining agricultural activities and sustaining the local ecosystem. With its strategic position along the Sand Draw river and its role in providing water for irrigation, fire protection, and stock purposes, this dam serves as a critical infrastructure for the community and highlights the intersection of water resource management and climate resilience in the region.

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.
