Exchange Park Lake Dam (Upper) dam
Exchange Park Lake Dam (Upper)
Exchange Park Lake Dam (Upper) is a vital water resource in Decatur, Georgia, primarily serving recreational purposes. The dam is an earth dam with a buttress core type, standing at a height of 26 feet and a hydraulic height of 17 feet. It has a storage capacity of 21 acre-feet and covers a surface area of 2 acres. The dam's spillway is uncontrolled, with outlet gates also being uncontrolled.
Despite being categorized as having a low hazard potential, the dam has not been officially rated for its condition assessment. The last inspection was conducted in September 2005, with a frequency of every 5 years. The risk assessment for Exchange Park Lake Dam (Upper) is moderate, with a DSAC (Dam Safety Action Classification) not yet assigned. With its location in DeKalb County, Georgia, and under the ownership of the local government, this dam plays a crucial role in the local water resource management and climate resilience efforts in the area.
While Exchange Park Lake Dam (Upper) currently meets the recreational needs of the community, there is a need for regular inspections and risk assessments to ensure its safety and functionality. With a moderate risk level and unknown condition rating, it is important for local authorities to prioritize the maintenance and management of this dam to prevent any potential hazards or emergencies in the future. The dam's role in water resource management and climate adaptation underscores the importance of proactive measures to safeguard its integrity and functionality for the benefit of the surrounding environment and community.

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 Exchange Park Lake Dam (Upper)
Where does the data for Exchange Park Lake Dam (Upper) 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.
