Summary
Completed in 1992, the dam boasts a storage capacity of 68 acre-feet with a maximum storage of 68 acre-feet. It serves as a crucial structure in the management of water resources in the area, specifically in the tributary to Cedar Fork.
Despite its significant hazard potential, Jarvis Lake Dam has not been rated for its condition assessment. The dam has not been inspected for some time, and details regarding its emergency action plan and risk assessment are also unavailable. However, the dam plays a vital role in providing water storage and regulation in the region, highlighting the importance of its maintenance and monitoring for the safety of surrounding communities and the environment.
As enthusiasts of water resources and climate, understanding the infrastructure and condition of dams like Jarvis Lake Dam is essential for ensuring the sustainable management of water systems. With its location in Franklin County, Missouri, and its association with the St. Louis District, the dam serves as a critical component in the local water management infrastructure. Further assessment and monitoring of Jarvis Lake Dam are necessary to address its hazard potential and ensure its continued effectiveness in water resource management.

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.
