Crooked Creek Lake Dam dam
Crooked Creek Lake Dam
Crooked Creek Lake Dam, located in DeKalb, Georgia, is a vital structure owned by the local government for the primary purpose of recreation. Built in 1987 by designers Walden-Ashworth, this earth dam stands at a height of 23 feet and spans a length of 760 feet. With a maximum storage capacity of 1111 acre-feet, the dam safeguards the area against flooding while providing a serene surface area of 55 acres for outdoor activities.
Despite its recreational benefits, Crooked Creek Lake Dam poses a high hazard potential due to its poor condition as assessed in January 2021. The dam's inspection frequency of twice a year reflects the ongoing efforts to monitor and manage its risks. With a moderate risk assessment rating, there is a need for proactive risk management measures to ensure the safety and structural integrity of this essential water resource in the region.
As a state-regulated entity under the Georgia-SAFE DAMS PROGRAM, Crooked Creek Lake Dam undergoes regular inspections, permitting, and enforcement to meet state regulatory standards. The dam's location along Crooked Creek adds to its significance in water resource management and climate resilience efforts. With its critical role in flood control and recreational enjoyment, continued attention and investment are essential to safeguard the community and enhance the sustainability of this valuable water infrastructure.

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 Crooked Creek Lake Dam
Where does the data for Crooked Creek 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 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 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.
