Summary

This picturesque lake serves primarily for recreational purposes and was completed in 1948, offering a tranquil escape for water resource and climate enthusiasts. With a dam height of 18 feet and a storage capacity of 250 acre-feet, Cypress Lake covers a surface area of 24.2 acres and is fed by the Brashear Creek.

Managed by the Mississippi Department of Environmental Quality, Cypress Lake has a high hazard potential but is currently assessed to be in satisfactory condition. Despite its uncontrolled spillway, the dam's risk assessment is moderate, indicating a need for ongoing monitoring and management measures. Surrounded by natural beauty and offering a haven for outdoor activities, Cypress Lake is a valuable resource in the region and contributes to the local ecosystem's water dynamics.

Enthusiasts interested in water resources and climate conservation can appreciate Cypress Lake's significance as a recreational hub while also acknowledging the importance of maintaining its infrastructure and monitoring its risk factors. With a focus on sustainable management and conservation efforts, Cypress Lake stands as a symbol of the delicate balance between human enjoyment and environmental stewardship in the face of changing climate conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
