Herbert Calloway Irrigation Pond Dam dam
Herbert Calloway Irrigation Pond Dam
Located in Tattnall, Georgia, the Herbert Calloway Irrigation Pond Dam stands as a testament to early 20th-century engineering, having been completed in 1932 for the primary purpose of irrigation. This private earth dam, with a height of 12 feet and a length of 640 feet, provides a storage capacity of 71 acre-feet, making it a crucial water resource for the surrounding area. Despite its age, the dam boasts a low hazard potential and a moderate risk assessment, indicating its stability and importance in managing water resources in the region.
The dam features an uncontrolled spillway and outlet gates, serving as essential components for water regulation and discharge. With a normal storage capacity of 38 acre-feet and a drainage area of 73 square miles, the Herbert Calloway Irrigation Pond Dam plays a vital role in supporting agricultural activities and maintaining water balance in the ecosystem. Although last inspected in 1988 and not currently rated for condition assessment, the dam's historical significance and functional efficiency are clear indicators of its enduring value in water management practices.
As water resource and climate enthusiasts explore the rich history and engineering marvel of the Herbert Calloway Irrigation Pond Dam, its contribution to sustainable irrigation practices and water conservation efforts in Georgia becomes evident. With its strategic location and meticulous design, this historic earth dam continues to serve as a critical infrastructure for water storage and distribution, highlighting the essential role of such structures in ensuring water security and ecosystem resilience in the face of evolving climate challenges.
Dam data reference
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 Herbert Calloway Irrigation Pond Dam
Where does the data for Herbert Calloway Irrigation Pond 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.
