Summary
Built in 1972 by the USDA NRCS, this dam serves as a crucial flood risk reduction infrastructure along the TR-Sand Creek. Standing at a height of 31 feet and with a NID storage capacity of 306 acre-feet, the dam plays a vital role in protecting the surrounding area from potential flooding events.
Managed by the Mississippi Department of Environmental Quality and regulated at the state level, the dam has a low hazard potential and a moderate risk assessment rating. With uncontrolled spillways and outlet gates, the dam is designed to handle maximum discharge while ensuring the safety of the downstream communities. Although its condition assessment is currently not rated, the dam continues to be inspected, maintained, and operated in accordance with state regulations and guidelines.
As a key piece of infrastructure for flood risk reduction in Carroll County, Mississippi, the Big Sand Watershed Structure Y-32-29 Dam showcases the importance of effective water resource management. With its strategic design and purposeful construction, the dam stands as a testament to the efforts made by local governments and agencies to protect communities and ecosystems from the impacts of extreme weather events and changing climate patterns.

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.
