Summary

This Earth-type dam stands at a height of 28 feet with a length of 670 feet, providing a storage capacity of 243 acre-feet. The dam is situated on TR-Crooked Run, and is regulated by the state with permitting and inspection requirements in place.

Despite being classified as having a high risk level, the condition of Wilcox Lake Dam is currently not rated. The dam does not have a spillway and features one outlet gate. The primary purpose of this structure is water supply, with a normal storage capacity of 133 acre-feet. While the hazard potential and condition assessment are not available, the dam's risk management measures and emergency preparedness status are also unspecified.

With the potential to impact water resources and climate in the area, Wilcox Lake Dam stands as a key infrastructure for water supply. As a private entity, the dam's management and regulation fall under state jurisdiction, with inspections and permitting ensuring its safety and functionality. The dam's construction and design details, along with its current condition assessment, reveal the importance of monitoring and maintaining such structures for the sustainable management of water resources.

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.
