About this dam

Duncan Park Lake Dam

Duncan Park Lake Dam, located in Spartanburg, South Carolina, is a significant earth dam constructed in 1935 primarily for recreational purposes. With a height of 42 feet and a length of 445 feet, the dam holds a maximum storage capacity of 213 acre-feet of water. The dam is situated on TR-FAIRFOREST CREEK and is owned and regulated by the local government, with oversight from the South Carolina Department of Health and Environmental Control (DHEC).

Despite being classified as having a significant hazard potential, Duncan Park Lake Dam is currently in fair condition, as assessed during its last inspection in December 2019. The dam has a history of modification and maintenance, with regular inspections conducted every three years to ensure its safety and structural integrity. The dam's emergency action plan was last revised in 1995, and further updates may be needed to align with current guidelines and risk management measures.

Water resource and climate enthusiasts will find Duncan Park Lake Dam to be a fascinating example of early 20th-century dam construction for recreational purposes. Its picturesque location and historical significance make it an important landmark in Spartanburg, South Carolina, while also serving as a vital structure for water storage and management in the region. With proper maintenance and oversight, Duncan Park Lake Dam continues to play a crucial role in supporting the community's recreational activities and water resource needs.

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 Duncan Park Lake Dam

Where does the data for Duncan Park Lake 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 Significant 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.
