Summary
Built in 1957, this earth dam stands at 20 feet high and spans 1200 feet in length, with a storage capacity of 100 acre-feet. Situated on the Main Ditch-OS river/stream, this dam plays a significant role in the local water resource management and provides opportunities for outdoor activities in the area.
Despite being privately owned, Mary Simpson Pond Dam is not regulated or inspected by the state authorities, presenting a potential hazard due to its significant hazard potential classification. The condition of the dam is currently not rated, indicating a lack of recent assessments and maintenance activities. Emergency action plans and risk assessments for the dam are also not readily available, raising concerns for the safety and management of the structure in case of unforeseen events.
The dam's presence in the Little Rock District highlights the importance of monitoring and maintaining such structures to ensure the safety of surrounding communities and the preservation of water resources. Enthusiasts interested in water resource management and climate change impacts on infrastructure should pay attention to the status and maintenance practices of Mary Simpson Pond Dam to mitigate potential risks and safeguard the environment.

Dam Data Reference
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.
