Summary

Owned privately, the dam stands at 28 feet high and has a hydraulic height of 22 feet, with a length of 192 feet. The dam has a storage capacity of 33.4 acre-feet, with a normal storage level of 18 acre-feet and a surface area of 2.5 acres.

Managed by the Natural Resources Conservation Service, the dam has a low hazard potential and a moderate risk assessment rating of 3. With uncontrolled spillways and outlet gates, the dam has not been inspected since July 2009. Despite its unregulated state, the dam is situated in a picturesque location, offering opportunities for outdoor recreation and leisure activities for visitors to enjoy.

While Gaeta Lake Dam may not be subject to state regulations or permitting, its presence contributes to the local landscape and provides a serene setting for water resource and climate enthusiasts to explore. As a private-owned earth dam, it serves as a reminder of the importance of maintaining and monitoring such structures to ensure their safety and longevity for future generations to enjoy.

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.
