Summary
This local government-owned earth dam stands at a height of 27 feet and spans a length of 804 feet, providing storage of 365 acre-feet and serving a drainage area of 1.18 square miles. The dam's primary purpose is flood risk reduction, with a spillway type of uncontrolled and a hazard potential rated as low.
Managed by the Mississippi Department of Environmental Quality, the Otoucalofa Creek Y-15-2 Dam is regulated, permitted, inspected, and enforced by state agencies to ensure its structural integrity and safety. Despite being classified as not rated in terms of condition assessment, the dam's risk assessment is moderate. With a risk management plan in place and emergency action preparedness measures anticipated but not yet confirmed, the dam plays a crucial role in mitigating flood risks in Calhoun County, Mississippi. Water resource and climate enthusiasts will find this dam's design and operation fascinating in its contribution to local flood control efforts.
As part of the Vicksburg District's water resource management infrastructure, the Otoucalofa Creek Y-15-2 Dam showcases the collaboration between federal and state agencies in ensuring the safety and functionality of critical earth dams. With a focus on flood risk reduction and a commitment to regulatory compliance and inspection, this dam stands as a testament to the importance of sustainable water resource management in the face of changing climate patterns. Its location in a high-risk area for flooding underscores the necessity of maintaining and monitoring such infrastructure to protect communities and ecosystems downstream.

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.
