About this dam

Lake Chinquapin Dam

Lake Chinquapin Dam, located in Greenwood, South Carolina, was completed in 1960 for the primary purpose of recreation. This private dam stands at a height of 27 feet and stretches 310 feet in length, providing a storage capacity of 334 acre-feet. With a surface area of 12 acres, the dam regulates water flow from the TR-Big Curltail Creek, contributing to the local ecosystem and providing essential recreational opportunities for the community.

Managed by the South Carolina Department of Health and Environmental Control, Lake Chinquapin Dam is regularly inspected and maintained to ensure its safety and functionality. The dam has a high hazard potential but is currently assessed to be in fair condition as of December 2020. Despite its age, the dam continues to serve as a vital resource for water management and outdoor activities in the region, attracting water resource and climate enthusiasts alike to its picturesque surroundings.

With its earth core and stone foundation, Lake Chinquapin Dam remains a key landmark in the Savannah District, offering a glimpse into the engineering feats of the past. As climate change continues to impact water resources, the dam plays a crucial role in water regulation and conservation efforts in the area. Whether enjoying a day of fishing or simply appreciating the beauty of the lake, visitors to Lake Chinquapin Dam can witness the intersection of human ingenuity and natural landscapes, making it a destination of interest for those passionate about water resource management and climate resilience.

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 Lake Chinquapin Dam

Where does the data for Lake Chinquapin 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.
