Bogan Dam dam
Bogan Dam
Bogan Dam, located in Union, South Carolina, was completed in 1971 and serves as a private recreational facility. The earth dam stands at a height of 34 feet and spans 1615 feet in length, providing a storage capacity of 300 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2019 revealed a poor state, prompting the need for ongoing inspections and maintenance.
Managed by the South Carolina Department of Health and Environmental Control, Bogan Dam overlooks the scenic TR-Swink Creek and offers a surface area of 25 acres for water enthusiasts and nature lovers to enjoy. While the dam remains state-regulated, its primary purpose remains recreation, with no associated locks or spillways. The dam's inspection frequency is set at 5 years, with the last assessment conducted in December 2019.
For water resource and climate enthusiasts, Bogan Dam presents a unique opportunity to explore the intersection of water management and recreational activities. With its serene location and historical significance, the dam stands as a testament to the importance of sustainable infrastructure development and maintenance in ensuring community safety and enjoyment. As efforts continue to monitor and improve the dam's condition, stakeholders are reminded of the critical role that water resources play in our daily lives and the need for proactive stewardship of these vital assets.
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.

About Bogan Dam
Where does the data for Bogan 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.
