Summary
Built in 1936 for recreational purposes, this earth dam reaches a hydraulic height of 16 feet and a structural height of 17 feet, with a length of 240 feet. With a storage capacity of 50 acre-feet, the dam serves as a recreational spot for the MT ZION CHURCH COMMUNITY, offering activities like fishing and boating.
Despite being labeled as 'Significant' in terms of hazard potential, the condition of R M Pendergrass is currently rated as 'Not Rated'. With no recent inspection data available, the emergency action plan (EAP) status and risk assessment measures remain unknown. The dam's associated structures and outlets are also not detailed, calling for further evaluation and management to ensure the safety and resilience of the dam against potential hazards and emergencies.
As water resource and climate enthusiasts, understanding the historical significance and environmental impact of dams like R M Pendergrass is crucial. By delving into the data and assessing the risk factors associated with these structures, we can work towards better management and conservation efforts to safeguard our water resources and mitigate potential threats to the surrounding communities and ecosystems.

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.
