Summary
Owned and regulated by the local government, this earth-type dam was designed by the USDA NRCS and completed in 1961. With a dam height of 21 feet and a storage capacity of 340 acre-feet, it plays a crucial role in managing the flow of the TR- Fork Creek E river.
Although the dam has a low hazard potential and is currently rated as not assessed for condition, it is subject to regular state inspections, enforcement, and permitting by the Mississippi Department of Environmental Quality. The primary purpose of the dam is flood risk reduction, and it operates with uncontrolled spillways and outlet gates. The risk assessment for the dam is moderate, highlighting the importance of ongoing risk management measures to ensure its continued effectiveness in protecting the surrounding area from potential flooding events.
Overall, the Bogue Watershed Structure Y-30-066 Dam serves as a key component of the water resource infrastructure in Webster County, Mississippi. Its historical significance, combined with its critical role in flood management, underscores the importance of maintaining and monitoring this structure to safeguard the local community and environment from water-related risks and challenges.

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.
