Summary

The dam, constructed with earth and buttress core types, stands at a height of 19.6 feet and has a maximum storage capacity of 256 acre-feet. With a surface area of 17 acres, the dam plays a crucial role in water resource management in the region.

Despite being classified as having a low hazard potential, the dam has a moderate risk assessment rating. Although the condition of the dam is currently not rated, regular inspections are conducted with a frequency of every 5 years to ensure its safety. With a spillway type of uncontrolled and uncontrolled outlet gates, the dam presents some challenges for risk management and emergency preparedness.

While Griner Pond Dam does not fall under the jurisdiction of state regulatory agencies, it is subject to inspections to assess its structural integrity and potential risks. As a key component in the local irrigation system, the dam serves as a vital resource for water supply in the area. Enthusiasts of water resources and climate change will find Griner Pond Dam to be an interesting case study in dam management and the intersection of infrastructure and environmental conservation efforts.

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.
