Oconee State Park Dam 1 dam
Oconee State Park Dam 1
Oconee State Park Dam 1, located in South Carolina, was completed in 1935 and serves primarily for recreational purposes. This earthen dam stands at a height of 33 feet and spans a length of 280 feet, with a storage capacity of 154 acre-feet. Situated on the TR-Jerry Creek, this dam is under state regulation by the South Carolina Department of Health and Environmental Control (DHEC), with regular inspections and enforcement to ensure its safety and compliance.
Despite being classified as having a high hazard potential, Oconee State Park Dam 1 is currently assessed to be in fair condition as of the last inspection in June 2019. The dam is equipped with outlet gates, but specific spillway details are not provided in the data. With a history of modifications unlisted, this dam continues to provide vital recreational opportunities while also serving as a vital component of water resource management in the region.
Water resource and climate enthusiasts interested in the Oconee State Park Dam 1 can appreciate its historical significance, engineering design, and ongoing maintenance efforts to ensure public safety and environmental protection. As an integral part of the Nashville District in South Carolina, this dam stands as a testament to the balance between human recreation and the preservation of natural resources in the region.

About Oconee State Park Dam 1
Where does the data for Oconee State Park Dam 1 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.

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.
