Little Coldstream Dam dam
Little Coldstream Dam
Little Coldstream Dam, located in Lexington, South Carolina, is a private earth dam primarily used for recreation purposes. Completed in 1940, this dam stands at a height of 15 feet and spans 320 feet in length, with a storage capacity of 60 acre-feet. Situated on the TR-RAWLS CREEK, this dam is under state regulation by the South Carolina Department of Health and Environmental Control (DHEC), with inspections conducted regularly to ensure its structural integrity.
Despite its picturesque setting and recreational value, Little Coldstream Dam poses a high hazard potential due to its current poor condition assessment. With a history of modifications and a drainage area of 4 square miles, the dam requires attention and potential risk management measures to mitigate any threats to downstream communities. The dam's emergency action plan (EAP) was last revised in 2016, highlighting the need for updated protocols and guidelines to enhance public safety in case of a breach or emergency situation.
As water resource and climate enthusiasts, it is crucial to monitor dams like Little Coldstream Dam closely to ensure their safety and integrity. With a high hazard potential and poor condition assessment, proactive maintenance and risk management measures are essential to prevent any potential disasters and protect both the environment and surrounding communities. By staying informed and advocating for necessary improvements, we can work towards preserving these vital structures for future generations.
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 Little Coldstream Dam
Where does the data for Little Coldstream 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.
