Summary
The dam, designed by Keith H. Mcraney, boasts an earth structure with stone core types and soil foundations, standing at a height of 31.81 feet and a length of 600 feet. Located in Lauderdale County, Mississippi, the dam contributes to the beauty and enjoyment of the surrounding area, offering a surface area of 22.8 acres and a drainage area of 0.17 square miles.
Despite its low hazard potential, the dam's condition assessment in 2017 was marked as unsatisfactory, pointing to potential issues that require attention. With a moderate risk rating and a history of inspections every five years, there is a need for continued monitoring and maintenance to ensure the safety and integrity of Rainbow Lakes # 4 Dam. The Mississippi Department of Environmental Quality oversees the regulation and enforcement of state laws related to the dam, emphasizing the importance of compliance with safety standards.
The dam's uncontrolled spillway and outlet gates add to its unique characteristics, providing a glimpse into the engineering marvel that is Rainbow Lakes # 4 Dam. As climate and water resource enthusiasts, this structure serves as a reminder of the delicate balance between harnessing nature for human benefit and the responsibility to protect and preserve these vital resources for future generations.

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.
