Summary
Built in 2006, this earth dam serves primarily for recreational purposes, offering visitors a tranquil escape amidst the beauty of nature. With a height of 29.5 feet and a storage capacity of 114.5 acre-feet, the dam plays a crucial role in regulating water levels and ensuring a sustainable water supply for the surrounding area.
Managed by the Mississippi Department of Environmental Quality, the dam's design by Billy E. Colson reflects a commitment to safety and environmental stewardship. While its hazard potential is currently undetermined, the dam's condition assessment is not rated, indicating the need for ongoing monitoring and maintenance. As a private structure under state jurisdiction, Richard Roberson Lake Dam serves as a vital component in the region's water infrastructure, highlighting the interconnectedness of water resources and climate adaptation efforts.
As climate change continues to impact water availability and quality, Richard Roberson Lake Dam serves as a critical tool in managing flood risks and preserving water resources for future generations. With a moderate risk assessment rating, the dam underscores the need for proactive risk management measures to mitigate potential hazards. By staying informed and engaged in the maintenance and operation of this essential infrastructure, water resource and climate enthusiasts can contribute to the resilience and sustainability of their local water systems.

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.
