Summary

Designed by the USDA NRCS, this private-owned Earth dam boasts a hydraulic height of 15 feet and a structural height of 18 feet, providing crucial protection to the surrounding area. With a maximum discharge capacity of 630 cubic feet per second, this dam plays a vital role in mitigating flood risks and ensuring the safety of the local community.

Despite its low hazard potential, Ouachita Creek Wid Site 1 has a moderate risk assessment rating, indicating the importance of ongoing monitoring and maintenance. While the dam remains in good condition and has not been rated, regular inspections are crucial to ensure its continued effectiveness in flood risk reduction. The dam's uncontrolled spillway type and outlet gates signify its reliance on natural flow patterns to regulate water levels, adding to its unique charm as a part of the local ecosystem.

With its picturesque location in Perry County, Arkansas, Ouachita Creek Wid Site 1 serves as a testament to the harmonious coexistence of infrastructure and nature. As water resource and climate enthusiasts, we can appreciate the vital role this dam plays in managing water flow and protecting the local environment. As we look to the future, continued vigilance and investment in dam safety measures will be essential to ensure the long-term resilience of Ouachita Creek Wid Site 1 and its surrounding watershed.

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.
