Summary
This earth dam stands at a height of 18 feet with a hydraulic height of 11 feet, serving the purpose of flood risk reduction and recreation. With a storage capacity of 465 acre-feet and a maximum discharge of 320 cubic feet per second, this dam plays a crucial role in managing water resources in the area.
Despite its high hazard potential, Big Creek Wid Site 11 has not been rated for its condition and has not been inspected since July 2016. The dam is categorized as having a moderate risk level (3), indicating the need for ongoing risk management measures to ensure its safety and functionality. While the dam features an uncontrolled spillway and outlet gates, there are no associated locks for navigation purposes. The structure covers a surface area of 76 acres and serves a drainage area of 0.9 square miles.
As water resource and climate enthusiasts, it is important to monitor and assess the condition of dams like Big Creek Wid Site 11 to ensure their effectiveness in flood risk reduction and water management. With its location on Big Creek-OS and its strategic role in the region's water infrastructure, this dam serves as a vital piece of the water resource puzzle in Craighead County, Arkansas. The collaboration between local government agencies, such as the USDA NRCS, is essential for maintaining and enhancing the resilience of such structures in the face of changing climate patterns and increasing water demands.

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.
