About this dam

Olympia Lake Dam

Olympia Lake Dam, located in Haralson, Georgia, serves as a vital recreational resource in the area. This private concrete dam on the Little River stands at a height of 23.8 feet, with a hydraulic height of 20.6 feet and a structural height of 20.6 feet. With a storage capacity of 1500 acre-feet and a surface area of 128 acres, this dam provides ample opportunities for outdoor activities and water sports for visitors.

Despite being classified with a low hazard potential, Olympia Lake Dam has a moderate risk assessment score of 3. The last inspection of the dam was conducted in October 2016, with an inspection frequency of 5 years. While the dam's condition has not been rated, it is reassuring to note that the emergency action plan (EAP) status and risk management measures are currently in place to ensure the safety and security of the surrounding community in case of any unforeseen events.

With its uncontrolled spillway and outlet gates, Olympia Lake Dam remains a popular destination for locals and visitors alike. The dam, although not state regulated, is regularly inspected to maintain its operational efficiency. As climate change continues to impact water resources, it is crucial to monitor and manage dams like Olympia Lake Dam to ensure their resilience in the face of changing environmental conditions.

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.

FAQ

About Olympia Lake Dam

Where does the data for Olympia Lake 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.
