Summary
The dam stands at a height of 30 feet and stretches 900 feet in length, serving primarily for flood risk reduction along the TR-Spring Brook Creek. With a storage capacity of 331 acre-feet and a normal storage of 33 acre-feet, this dam plays a crucial role in managing water resources in Pontotoc County.
Despite being classified as having a low hazard potential, SCS-Sandy Creek Site-29 is considered to have a very high risk level, emphasizing the importance of regular inspections and maintenance. Although the last inspection was conducted in 1980, the dam is still operational and equipped with a controlled spillway and a single valve outlet gate. The dam poses minimal risk to surrounding communities, but continuous risk management measures are essential to ensure its structural integrity and effectiveness in flood control.
As a key infrastructure for water resource management in the region, SCS-Sandy Creek Site-29 highlights the intersection of climate resilience and sustainable development. With the potential for increased extreme weather events due to climate change, the proper maintenance and monitoring of this dam are crucial for safeguarding local communities and ecosystems against flooding and water scarcity.

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.
