Summary

The dam, classified as an Earth dam, has a hydraulic height of 15 feet and a structural height of 20 feet. It has a storage capacity of 50 acre-feet and is situated on Mountain Creek-Os, a river or stream in the area.

Despite being privately owned, the dam is subject to state inspections, with the last inspection conducted in October 2017. It has a low hazard potential and is currently deemed to be in a condition that is not rated. The dam has not been modified in recent years and does not have a designated Emergency Action Plan in place. With its picturesque location and multiple purposes including recreation, Stony Mountain Lake Dam #2 serves as an essential water resource for the local community.

As an enthusiast for water resources and climate, the unique features of Stony Mountain Lake Dam #2 make it an intriguing structure to study. Its role in fire protection, stock maintenance, and recreational activities highlight the importance of sustainable water management practices in the region. With its low hazard potential and stable condition, the dam stands as a testament to the careful design and maintenance required to ensure the safety and functionality of water infrastructure in the face of changing climate conditions.

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.
