Summary

Built in 1970, this earth dam stands at a height of 26 feet and has a length of 455 feet, creating a fish and wildlife pond with a storage capacity of 50 acre-feet. The primary purpose of the dam is for fire protection, stock, small fish pond, fish and wildlife habitat, and recreation, making it a valuable resource for the local community.

Despite being privately owned and not regulated by the state, Wright Dam has a low hazard potential and has not received a condition assessment rating. The dam's risk assessment is moderate, indicating a level 3 risk, with no emergency action plan (EAP) in place. The dam has not been inspected since 1980, and there are no outlet gates or associated structures. While the risk level is moderate, the dam continues to serve its intended purposes effectively and remains an important feature in the area for water resource and climate enthusiasts to explore and appreciate.

Overall, Wright Dam is a unique and valuable structure that provides essential benefits for fish and wildlife, recreation, and fire protection in the Bollinger County area of Missouri. While it may not be regulated by the state, the dam serves its purposes efficiently and safely, with a low hazard potential and moderate risk level. As a private entity, it stands as a testament to the importance of maintaining and managing water resources for both environmental and community needs.

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.
