Summary
With a maximum storage capacity of 262.2 acre-feet and a normal storage level of 157.5 acre-feet, the dam spans 399 feet in length and stands at a height of 26.1 feet. The dam's hydraulic and structural heights are 23.3 feet, making it a key feature for water resource management in the area.
Although Foley Lake Dam #1 has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment, it is subject to periodic inspections every five years to ensure its safety and functionality. The dam features an uncontrolled spillway and outlet gates, and while it has not been modified in recent years, it is considered to have a moderate risk level (3) according to the risk assessment conducted on the structure. Despite not being regulated by the state, the dam remains under jurisdiction and undergoes regular inspections to ensure its continued safe operation.
For water resource and climate enthusiasts, Foley Lake Dam #1 presents an intriguing case study of a privately owned dam serving a recreational purpose in a rural setting. With its unique design features and moderate risk level, the dam showcases the delicate balance between human-made infrastructure and natural resources. As conversations around water management and climate resilience continue to evolve, the maintenance and monitoring of dams like Foley Lake Dam #1 will be crucial in ensuring the safety and sustainability of our water resources for future generations.

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.
