Summary

This dam has a primary purpose of recreation and stands at a hydraulic height of 24.2 feet with a structural height of 27.1 feet. It holds a normal storage capacity of 29 acre-feet and covers a surface area of 3 acres, serving as a tranquil spot for outdoor enthusiasts to enjoy.

Situated on Brush Creek-Tr, Wright Lake Dam has a low hazard potential and has been deemed to be in satisfactory condition during its last assessment in January 2013. The dam has not been modified in recent years and is not state regulated, although it undergoes regular inspections to ensure its safety and functionality. With a maximum discharge capacity of 90 cubic feet per second, this earth dam provides a serene setting for water resource and climate enthusiasts who appreciate the beauty and importance of sustainable water management practices.

Although not extensively funded or managed by federal agencies, Wright Lake Dam continues to play a vital role in providing recreational opportunities for the local community.

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.
