Summary
Situated on Blakely Creek, this earth-type dam stands at a height of 17.1 feet, with a hydraulic height of 14.1 feet and a structural height of 22.1 feet. It has a storage capacity of 88.2 acre-feet, with a normal storage level of 55.8 acre-feet spread over a surface area of 9.9 acres.
Managed by the Mississippi Department of Environmental Quality, the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its recreational focus, the dam is also regulated and inspected by the state authorities, ensuring that it meets safety standards. While it does not have a detailed risk assessment, it is categorized as having a moderate risk level.
For water resource and climate enthusiasts, Lynn Robertson Dam presents an intriguing case study of a privately-owned structure that balances recreational use with state regulation and safety measures. Its presence on Blakely Creek adds to the local landscape and provides a valuable water storage capacity for the area. With its moderate risk level and low hazard potential, the dam represents a harmonious integration of human activity with natural resources, making it an interesting site to observe and study in the context of water management and climate resilience.

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.
