Mathias Pond Dam dam
Mathias Pond Dam
Mathias Pond Dam, located in Allendale, South Carolina, is a state-regulated structure with a height of 17 feet and a storage capacity of 208 acre-feet. The dam is under the jurisdiction of the South Carolina Department of Health and Environmental Control (SC DHEC) and has been inspected regularly, with the last assessment conducted in December 2017. Despite being classified as having a low hazard potential, the dam's condition assessment was rated as poor during the same inspection.
The dam does not have a designated primary purpose, and specific details about its design, construction, and purpose are not listed in the available data. However, it is noted that Mathias Pond Dam is associated with no other structures and has not undergone any modifications in recent years. While the dam's emergency action plan status and risk assessment information are not provided, it is crucial to monitor and address the poor condition assessment to ensure the safety and integrity of the structure for both water resource management and climate resilience purposes.
Given its location and regulatory oversight, Mathias Pond Dam serves as a vital component of water management in the area, reflecting the importance of maintaining and monitoring infrastructure for sustainable water resource utilization and climate adaptation. The dam's proximity to Congressional District 06 in South Carolina highlights the interconnectedness of water infrastructure, regulatory agencies, and emergency preparedness efforts in safeguarding communities and ecosystems against potential hazards. As water resource and climate enthusiasts, it is essential to advocate for continued assessment and maintenance of structures like Mathias Pond Dam to mitigate risks and ensure the resilience of water systems in the face of changing environmental conditions.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Mathias Pond Dam
Where does the data for Mathias Pond Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
