Summary

Built in 1965, this Earth dam stands at a structural height of 12 feet with a hydraulic height of 7 feet. It spans a length of 525 feet and has a maximum storage capacity of 194 acre-feet, with a normal storage capacity of 62 acre-feet. The dam sits on the Amason Creek and is situated in a low hazard potential area.

Despite not being regulated by the state, Anthony Lake Dam is a vital component for recreational activities in the region, offering a surface area of 25.5 acres for visitors to enjoy. With a drainage area of 2.58 square miles and a maximum discharge of 3330 cubic feet per second, the dam provides a picturesque setting for nature enthusiasts and water resource aficionados alike. Its low hazard potential and not rated condition assessment make it a safe and serene location for outdoor activities.

Managed by private owners, Anthony Lake Dam has not been subject to state inspections or enforcement. While lacking in certain regulatory oversight, the dam continues to serve as a popular spot for fishing, boating, and other leisure pursuits. As a key feature on the Amason Creek, it contributes to the local ecosystem and provides a tranquil environment for individuals to appreciate the intersection of water resources and climate dynamics in the area.

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.
