Summary

Built in 1986, this earth dam stands at a height of 19 feet and has a storage capacity of 195 acre-feet. The dam serves multiple purposes and is associated with the Muddy River-OS, with a drainage area of 0.1 square miles.

Despite its low hazard potential, the dam's condition was assessed as fair during its last inspection in 2016. With a risk assessment rating of 2 (high), there is a need for effective risk management measures to ensure the safety and stability of the structure. The dam does not have a spillway and no outlet gates, posing challenges in managing potential overflow events. The surrounding area covers 16.2 acres, providing an essential water resource for the region.

In the event of an emergency, it is crucial for stakeholders to have an updated emergency action plan in place to mitigate risks and ensure community safety. With its unique design and location, Rgs Dam Pond E2 stands as a testament to the importance of proper water resource management and climate resilience in the face of changing environmental 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.
