Lake Caire Yelleau Dam Dam
Lake Caire Yelleau Dam
Lake Caire Yelleau Dam, located in Dorchester, South Carolina, was completed in 1977 and serves as a recreational spot for water resource and climate enthusiasts. This privately owned earth dam stands at 15 feet high and spans 440 feet in length, creating a picturesque 8-acre surface area that offers various outdoor activities. The dam holds a storage capacity of 52 acre-feet, with normal storage levels reaching 30 acre-feet.
Managed by the South Carolina Department of Health and Environmental Control, the dam has a fair condition assessment and a high hazard potential. Regular inspections are conducted to ensure public safety, with the last assessment completed in February 2021. Despite its age, the dam continues to provide a popular destination for locals and visitors alike, offering a tranquil setting for relaxation and recreation along TR-NEGRO BRANCH river.
While the dam's spillway type and outlet gates are unspecified, its design and construction have stood the test of time, enhancing the surrounding landscape and providing a haven for wildlife and outdoor enthusiasts. With its rich history and scenic beauty, Lake Caire Yelleau Dam remains a valuable asset for the community, inviting exploration and appreciation of South Carolina's water resources.

About Lake Caire Yelleau Dam
Where does the data for Lake Caire Yelleau 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 below 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.
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.
