Summary
This private earth dam on the TR-Salt Fork Blackwater River has a height of 15 feet and a storage capacity of 160 acre-feet, with a normal storage level of 100 acre-feet. The dam covers a surface area of 20 acres and has a drainage area of 48 square miles.
Despite being privately owned and not regulated by the state, Robertson Lake Dam poses a high hazard potential. The condition assessment of the dam is currently not rated, and there is no information available regarding emergency preparedness, risk assessment, or risk management measures. The dam's inspection frequency is listed as 0, indicating a lack of recent inspections or assessments.
Enthusiasts of water resources and climate may find Robertson Lake Dam intriguing due to its historical significance and its potential impact on the surrounding area. The dam's high hazard potential raises concerns about its safety and the need for proper maintenance and monitoring to ensure the protection of downstream communities and ecosystems. Further research and attention to emergency preparedness and risk assessment are crucial for the long-term sustainability and safety of Robertson Lake Dam.

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.
