Oberlochen Lake Dam No. 2 dam
Oberlochen Lake Dam No. 2
Oberlochen Lake Dam No. 2, located in Douglasville, Georgia, is a local government-owned structure primarily used for recreation purposes. This Earth-type dam, with a height of 19.9 feet, provides a storage capacity of 121 acre-feet and covers a surface area of 12.7 acres. Despite being unlisted for the year of completion, the dam has a low hazard potential and is inspected every 5 years, with the last inspection conducted in July 2018.
The dam's spillway type is uncontrolled, with uncontrolled outlet gates. It is not state-regulated but falls under the jurisdiction of Georgia. The risk assessment for Oberlochen Lake Dam No. 2 is rated as moderate, with a DSAC assigned date, although specifics on risk management measures and inundation maps are not provided. With its beautiful recreational setting and low hazard potential, this dam serves as a valuable water resource for the community, allowing for both enjoyment and safety in a serene environment.
Water resource and climate enthusiasts interested in the Oberlochen Lake Dam No. 2 will appreciate its unique Earth-type design and the opportunities it provides for recreational activities in the area. The dam's location in Paulding County, Georgia, showcases the importance of maintaining and managing water resources for both public enjoyment and safety. As a non-federally regulated structure with a low hazard potential, Oberlochen Lake Dam No. 2 represents a harmonious balance between environmental conservation and human interaction with the natural landscape.
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 Oberlochen Lake Dam No. 2
Where does the data for Oberlochen Lake Dam No. 2 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.
