James K Jarrett Dam dam
James K Jarrett Dam
The James K Jarrett Dam, located in Aiken, South Carolina, is a privately owned structure primarily used for recreation. Completed in 1960, this Earth-type dam stands at a height of 10 feet and has a length of 520 feet. With a storage capacity of 50 acre-feet and a surface area of 10 acres, the dam serves as a popular spot for outdoor enthusiasts to enjoy various water activities.
Despite its low hazard potential, the dam's condition has been assessed as poor during the last inspection in August 2017. The dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC) and is subject to state permitting, inspection, and enforcement. The dam's emergency action plan (EAP) status and risk management measures are currently unknown, highlighting the need for ongoing monitoring and maintenance to ensure its structural integrity and the safety of surrounding communities.
With its location on the TR-ISLAND CREEK and its association with recreational purposes, the James K Jarrett Dam stands as a significant landmark in South Carolina. As climate change continues to impact water resources, it is essential for dam owners and regulatory agencies to prioritize the maintenance and safety of these structures to mitigate potential risks and ensure the sustainability of water infrastructure for future generations.

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 James K Jarrett Dam
Where does the data for James K Jarrett 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.
