Summary
This earth dam, completed in 1991, stands at a height of 28.8 feet and stretches 1970 feet in length, providing storage of 4441 acre-feet and serving a drainage area of 10 square miles. Despite its low hazard potential, the dam has a moderate risk assessment of 3 due to its uncontrolled spillway and outlet gates.
Owned by the local government and regulated by the Arkansas Natural Resources Commission, Fourche Creek Wid Site 20 is inspected as per state regulations for its operation, maintenance, and enforcement. The dam's primary purpose is flood risk reduction, with a focus on protecting the surrounding community from potential inundation and ensuring public safety. While the dam's condition has not been rated and its emergency action plan is not yet prepared, continuous monitoring and risk management measures are in place to mitigate any potential risks associated with the structure.
In the event of any emergencies or changes in risk assessment, the local authorities, including the designated emergency contacts, are tasked with ensuring the safety and well-being of the residents in the area. With its strategic location and design, Fourche Creek Wid Site 20 plays a crucial role in water resource management and climate resilience efforts in the region, highlighting the importance of sustainable infrastructure for safeguarding communities against natural disasters and climate challenges.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
