Marshall Dam dam
Marshall Dam
Marshall Dam, located in York, South Carolina, is a privately owned earth dam completed in 1954 primarily for recreational purposes. With a height of 29 feet and a length of 710 feet, the dam creates a reservoir with a maximum storage capacity of 146 acre-feet. The dam sits on Taylor Creek and is regulated by the South Carolina Department of Health and Environmental Control, ensuring regular inspections and enforcement of safety standards.
Despite its fair condition assessment and high hazard potential, Marshall Dam remains a popular destination for water resource and climate enthusiasts seeking outdoor recreational activities. The dam's surface area of 10 acres provides ample space for fishing, boating, and other water-based activities. While there are no associated structures or locks, the dam's emergency action plan status and risk assessment measures remain unspecified, leaving room for potential enhancements in safety protocols.
As supporters of sustainable water management and climate resilience, enthusiasts should keep an eye on Marshall Dam's ongoing maintenance and risk management efforts. With its picturesque location and recreational opportunities, the dam serves as a vital resource for the local community and a reminder of the importance of balancing human enjoyment with environmental stewardship in the face of changing climates. Stay informed about the latest updates and safety measures surrounding Marshall Dam to continue enjoying its benefits while promoting responsible water resource practices.

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 Marshall Dam
Where does the data for Marshall 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.
