Calvert Impoundment Dam dam
Calvert Impoundment Dam
Calvert Impoundment Dam, located in Wilkinson, Georgia, is a private structure with a height of 60 feet and a length of 2217 feet. The dam, primarily made of earth with a buttress core type, was designed by Engelhard Corporation and is under state jurisdiction for inspection. Although the dam is not regulated by a state agency, it is regularly inspected, with the last inspection conducted in January 2018.
The dam has a storage capacity of 1361 acre-feet, with a normal storage level of 1088 acre-feet and a surface area of 54 acres. It features an uncontrolled spillway and outlet gates, with a moderate risk assessment rating of 3. The hazard potential of the dam is currently undetermined, and its condition assessment is not rated. Despite these uncertainties, the dam is deemed to have moderate risk management measures in place, ensuring the safety and security of the surrounding area.
Calvert Impoundment Dam, situated in a picturesque location in Georgia, serves as a vital water resource for the region. With its impressive storage capacity and strategic design, the dam plays a crucial role in managing water flow and providing essential services to the community. As water resource and climate enthusiasts, the intricate details of the dam's construction and functionality offer valuable insights into the intersection of engineering, environmental protection, and public safety in the context of 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 Calvert Impoundment Dam
Where does the data for Calvert Impoundment 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 Undetermined 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.
