Summary
Designed by the USDA NRCS and completed in 1967, this earth dam stands at a height of 47.4 feet and stretches 1660 feet in length. Its primary purpose is flood risk reduction, serving the Thompson Creek and boasting a drainage area of 13.45 square miles.
With a storage capacity of 2650 acre-feet and a maximum discharge of 8920 cubic feet per second, Big Sand Watershed Structure Y-32-10 Dam plays a crucial role in managing water resources in the region. However, its condition assessment is marked as poor and it has a high hazard potential, highlighting the need for maintenance and potential upgrades. Despite these challenges, the dam continues to be regulated, inspected, and enforced by the Mississippi Department of Environmental Quality to ensure public safety and environmental protection.
Water resource and climate enthusiasts will find this dam's data intriguing, as it offers insights into the infrastructure that helps mitigate flooding and manage water flow in the area. The moderate risk assessment indicates the importance of proactive management measures to address potential hazards. As an integral part of the local landscape, Big Sand Watershed Structure Y-32-10 Dam stands as a testament to the ongoing efforts to balance water resource management with environmental stewardship in Mississippi's waterways.

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.
