Coastal Timber Co Dam dam
Coastal Timber Co Dam
Coastal Timber CO Dam, located in Horry, South Carolina, stands as a testament to human ingenuity and the delicate balance between water resource management and recreational enjoyment. Completed in 1970, this private-owned Earth dam serves primarily for recreation purposes, offering a serene escape for visitors to enjoy the picturesque Grier Swamp. With a height of 9 feet and a length of 900 feet, the dam boasts a storage capacity of 140 acre-feet, providing a tranquil surface area of 28 acres for outdoor activities.
Despite its low hazard potential, the dam's condition assessment in 2019 revealed poor maintenance, underscoring the importance of regular inspections and upkeep to ensure its structural integrity and safety. Managed by the South Carolina Department of Health and Environmental Control, the dam is subject to state regulation, permitting, inspection, and enforcement, highlighting the critical role of government oversight in safeguarding our water resources. As climate change poses new challenges to our water infrastructure, it is imperative to prioritize the maintenance and upkeep of dams like Coastal Timber CO Dam to mitigate risks and uphold the beauty and functionality of our natural landscapes.
Dam data reference
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 Coastal Timber Co Dam
Where does the data for Coastal Timber Co 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.
