Summary

This private dam, regulated by the Department of Natural Resources, serves a primary purpose of recreation, offering a serene setting for outdoor activities. With a dam height of 31 feet and a storage capacity of 42.1 acre-feet, the dam contributes significantly to the local water ecosystem, providing a surface area of 3.3 acres and serving a drainage area of 0.06 square miles.

The dam, completed in an unspecified year, boasts a satisfactory condition assessment as of May 2017, with a low hazard potential. Inspected every five years, the dam is equipped to handle its maximum storage capacity of 42.1 acre-feet and normal storage of 24.6 acre-feet. As a critical part of the water infrastructure in the region, the Hawthorne Valley Country Club Lake Dam ensures water security and recreation opportunities, while maintaining a commitment to safety and regulatory compliance. The dam's location near a tributary to Tinkers Creek further enhances its ecological significance, making it a valuable asset for water resource and climate enthusiasts 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.
