About this dam

Perry Lake Dam

Perry Lake Dam in Terrell, Georgia, stands as a vital structure for recreation enthusiasts and water resource advocates alike. Owned privately and standing at a height of 18.2 feet, this earth dam offers a storage capacity of 101 acre-feet and covers an impressive surface area of 10.1 acres. While primarily serving recreational purposes, Perry Lake Dam also plays a crucial role in managing the surrounding drainage area of 360 square miles.

Despite its low hazard potential, Perry Lake Dam has a moderate risk assessment rating, indicating the need for ongoing monitoring and management. With its uncontrolled spillway and outlet gates, this dam poses a moderate risk level that requires regular inspections to ensure its structural integrity. While its condition assessment is currently marked as "Not Rated," the dam's last inspection in August 2016 offers valuable insights into its overall safety and maintenance needs.

Located in the Mobile District with Congressman Sanford D. Bishop Jr. representing the area, Perry Lake Dam is a key component of Georgia's water infrastructure. As climate change continues to impact water resources, the importance of maintaining and monitoring structures like Perry Lake Dam becomes increasingly vital for safeguarding both the environment and the 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.

FAQ

About Perry Lake Dam

Where does the data for Perry 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.
