Summary
Completed in 1964, the dam stands at a height of 17 feet with a hydraulic height of 16 feet, creating a storage capacity of 84 acre-feet. The dam is located on the Unit of Tumbaloo Creek in Rankin County, Mississippi, and covers a surface area of 8.3 acres with a drainage area of 0.06 square miles.
Despite its low hazard potential, the dam's condition assessment is rated as poor as of the last inspection in 2015. The dam has an uncontrolled spillway type and is inspected every 5 years. The risk assessment for the dam is moderate, indicating potential concerns that may need to be addressed in the future. The dam is regulated by the Mississippi Department of Environmental Quality, ensuring that necessary permits, inspections, and enforcement measures are in place to manage its operation and safety.
For water resource and climate enthusiasts, Robin Hood Lake Number 4 Dam provides insight into the management and maintenance of dams in Mississippi. With its recreational purpose and moderate risk assessment, the dam serves as a vital structure in the local water infrastructure. As discussions around climate change and water conservation continue, understanding the condition and regulation of dams like Robin Hood Lake Number 4 Dam is crucial for ensuring the safety and sustainability of water resources in the region.

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.
