Summary
Completed in 1977, this Earth type dam stands at a height of 25 feet and stretches 460 feet in length. With a storage capacity of 25 acre-feet, the dam plays a crucial role in maintaining water levels for recreational activities, fire protection, and grade stabilization in the area.
Despite being unregulated by the state and federal agencies, Jarvis Lake Dam is considered to have a low hazard potential and a moderate risk assessment level. With a spillway width of 10 feet and a maximum discharge of 6 cubic feet per second, the dam ensures proper water flow and management for the surrounding 32-acre drainage area. While the dam's condition assessment is currently not rated, its structural integrity and risk management measures are continuously monitored to ensure the safety and well-being of the community.
As a vital component of the local ecosystem, Jarvis Lake Dam serves as a sanctuary for various wildlife species and provides a tranquil setting for outdoor enthusiasts. With its strategic location along TR-Big Creek and its capacity to support diverse recreational activities, the dam stands as a testament to the harmonious coexistence between water resources and environmental preservation in the region.

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.
