Summary
Completed in 2013, this earth dam stands at a height of 24.5 feet and has a maximum storage capacity of 308.7 acre-feet. With a moderate risk assessment rating of 3, the dam is categorized as having low hazard potential, indicating a relatively low level of risk associated with its operation.
Managed by the Mississippi Department of Environmental Quality, the Northeast Weyerhaeuser Lake Dam is subject to state regulation, permitting, inspection, and enforcement. The dam is situated on the UNT of Magowah Creek, within the jurisdiction of the Mobile District of the US Army Corps of Engineers. Despite not having a designated dam type, the structure features a buttress core design and an uncontrolled spillway type. The dam's associated structures, such as outlet gates and locks, are not applicable, further emphasizing its primary function for irrigation purposes.
Water resource and climate enthusiasts will find Northeast Weyerhaeuser Lake Dam to be a fascinating case study in dam engineering and management. With its strategic location and critical role in providing water for irrigation, this structure exemplifies the importance of proper regulation, inspection, and risk assessment to ensure the safety and sustainability of water resources in the region. As a relatively new construction, the dam's condition assessment is yet to be rated, presenting an opportunity for ongoing monitoring and maintenance to uphold its operational efficiency and safety standards.

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.
