Williams Sediment Pond E dam
Williams Sediment Pond E
Williams Sediment Pond E, located in Berkeley, South Carolina, was completed in 1972 and serves as a key structure for managing sediment and water resources in the area. This earth dam, with a height of 11 feet and a length of 1679 feet, has a storage capacity of 60 acre-feet and covers a surface area of 10 acres. It is primarily regulated by the South Carolina Department of Health and Environmental Control (DHEC) and is classified as having a low hazard potential with a fair condition assessment as of November 2017.
The dam's primary purpose is listed as "Other," indicating its role in managing sediment and water flow in the Cooper River offstream. It is owned and operated by a public utility and falls under state jurisdiction for permitting, inspection, and enforcement. The structure has not undergone significant modifications in recent years and is inspected every five years to ensure its continued safety and effectiveness. With its location in a critical watershed area, the Williams Sediment Pond E plays a vital role in protecting water resources and mitigating potential environmental risks in the region.
As a key component of water resource management in the area, Williams Sediment Pond E stands as a testament to proactive sediment control and conservation efforts. With its low hazard potential and fair condition assessment, the structure continues to play a crucial role in maintaining water quality and flow in the Cooper River offstream. Under the supervision of the South Carolina DHEC, the dam undergoes regular inspections to uphold safety standards and ensure its ongoing effectiveness in protecting the surrounding environment. As climate and water resource enthusiasts, monitoring and supporting structures like Williams Sediment Pond E is essential for sustainable resource management and environmental stewardship in the region.

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 Williams Sediment Pond E
Where does the data for Williams Sediment Pond E 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.
