About this dam

Gramling Pond No4 Dam

Gramling Pond No4 Dam, located in Spartanburg, South Carolina, was completed in 1973 and stands at a height of 23 feet with a length of 310 feet. This earth dam, primarily used for recreation, has a storage capacity of 57 acre-feet and a surface area of 5 acres. Situated on the TR-SOUTH PACOLET RIVER, the dam is regulated by the South Carolina Department of Health and Environmental Control (SC DHEC) and undergoes regular inspections to ensure safety and compliance.

Despite being classified as having a low hazard potential, Gramling Pond No4 Dam is currently in poor condition as of the last assessment in May 2017. The dam is subject to inspection every 5 years, with the last inspection revealing the need for maintenance or repairs. With a lack of Emergency Action Plans (EAP) and updated risk assessments, there are concerns about the dam's ability to withstand potential emergencies or natural disasters. Although the dam serves as a recreational site, its structural integrity and safety measures require attention to mitigate any future risks.

As water resource and climate enthusiasts, there is a need to monitor the condition of Gramling Pond No4 Dam closely and advocate for necessary improvements to ensure the safety of the surrounding community and the preservation of the water resources it regulates. By emphasizing the importance of regular maintenance, emergency preparedness, and risk assessments, we can work towards safeguarding this vital infrastructure for both recreational and environmental purposes.

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.

FAQ

About Gramling Pond No4 Dam

Where does the data for Gramling Pond No4 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.
