Summary
Standing at a height of 25 feet and a length of 440 feet, the dam boasts a maximum storage capacity of 97 acre-feet and serves as a critical structure within the region's water resource management system. With a low hazard potential and moderate risk assessment, the dam provides essential debris control and recreational opportunities for the surrounding area.
Managed by a private entity, Griffith Lake Dam has not been rated for its condition assessment but is considered to meet regulatory guidelines. The dam features an uncontrolled spillway with a width of 22 feet and has not been modified in recent years. Despite its low hazard potential, the dam plays a crucial role in mitigating flood risks and ensuring the safety of local communities downstream. With a drainage area of 205 square miles and a surface area of 5 acres, the dam contributes to the overall water resource management of the region.
While Griffith Lake Dam may not be under state jurisdiction or regulation, its strategic location and design make it a key component in maintaining water levels and reducing flood risks in the area. As a focal point for recreation and flood mitigation efforts, the dam stands as a testament to the importance of sustainable water resource management practices in the face of changing climate conditions. With its impact on the local ecosystem and community, Griffith Lake Dam serves as a vital structure in ensuring the resilience and adaptability of the region's water infrastructure.

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.
