Summary
With a primary purpose categorized as "Other," the dam at Berryhill Lake is of the Earth type with a height of 8 feet and a length of 11,200 feet. The reservoir has a storage capacity of 1,200 acre-feet, making it an essential water resource for the area.
Despite being privately owned, Berryhill Lake is not regulated or inspected by the state, and it has a low hazard potential with a moderate risk assessment rating. The reservoir features an uncontrolled spillway and outlet gates, with no associated locks or structures. The risk management measures and emergency preparedness status of Berryhill Lake are currently not rated or assessed, indicating a potential area for improvement in the future.
Water and climate enthusiasts will find Berryhill Lake to be an intriguing case study in private water resource management and the need for heightened risk assessment and emergency preparedness in the face of changing climate conditions. With its serene location near Isola, Mississippi, Berryhill Lake serves as a valuable reminder of the importance of maintaining and protecting our water 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.
