About this dam

Cedar Grove Lake Dam

Cedar Grove Lake Dam in Fulton County, Georgia, stands as a testament to the ingenuity of its unknown designers who completed the structure in 1945 for recreational purposes along Pea Creek. This private dam, primarily built for recreation, is an earth-type structure with a buttress core, boasting a height of 38.9 feet and a length of 528 feet. The dam holds a storage capacity of 510 acre-feet but currently maintains a normal storage level of zero, covering a surface area of 32 acres within a drainage area of 625 acres. Despite its uncontrolled spillway and outlet gates, the dam poses a low hazard potential and remains in a not-rated condition as of the last inspection in 2017.

Located in Fairburn, Georgia, Cedar Grove Lake Dam is a picturesque spot for water resource and climate enthusiasts to explore. With its serene surroundings and historical significance, the dam offers visitors a glimpse into the region's past while providing a tranquil setting for outdoor activities. While the dam does not fall under state regulation or permitting, it undergoes regular inspections to ensure its structural integrity and safety. The risk assessment for Cedar Grove Lake Dam indicates a moderate level of risk, although specific risk management measures are not detailed.

As a vital part of the local landscape, Cedar Grove Lake Dam serves as a valuable recreational asset for both residents and visitors to enjoy. While its exact purpose may have evolved over the years, the dam's role in providing leisure opportunities and contributing to the area's natural beauty remains unchanged. With its rich history, unique design features, and peaceful setting, Cedar Grove Lake Dam stands as a testament to human innovation and the enduring connection between water resources and climate dynamics.

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 Cedar Grove Lake Dam

Where does the data for Cedar Grove 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.

Premium feature

Favorites and alerts are part of Snoflo Premium. Save reservoirs, set storage thresholds, and get push notifications when conditions cross.
