J B Johnson Pond Dam dam
J B Johnson Pond Dam
J B Johnson Pond Dam, located in Spartanburg, South Carolina, is a private recreational dam built in 1955 on the TR-Holston Creek. Standing at a height of 33 feet and a length of 325 feet, this earth dam provides a storage capacity of 37 acre-feet for recreational purposes. Despite its fair condition assessment from the latest inspection in October 2019, the dam is classified as having a high hazard potential.
Managed by the South Carolina Department of Health and Environmental Control (SC DHEC), J B Johnson Pond Dam is subject to state regulation, permitting, inspection, and enforcement. The primary purpose of the dam is for recreation, with a normal storage capacity of 30 acre-feet and a surface area of 3 acres. The dam's hazard potential, coupled with its age and condition, highlights the importance of ongoing monitoring and maintenance to ensure the safety and integrity of the structure.
As a focal point for water resource and climate enthusiasts, J B Johnson Pond Dam offers an intriguing case study in private dam ownership and management. With its location on the TR-Holston Creek and the potential risks associated with a high hazard classification, this dam serves as a reminder of the critical role that proper maintenance and oversight play in ensuring the safety of these structures and the surrounding communities.

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 J B Johnson Pond Dam
Where does the data for J B Johnson 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 High 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.
