Alto Correctional Institute Water Supply Lake Dam dam
Alto Correctional Institute Water Supply Lake Dam
Located in Banks, Georgia, the Alto Correctional Institute Water Supply Lake Dam stands as a crucial structure for water resource management in the area. Built in 1930, this Earth type dam spans 238 feet in length and reaches a height of 39 feet, primarily serving the purpose of water supply. With a storage capacity of 35 acre-feet and a drainage area of 115 square miles, this dam plays a key role in regulating water flow and ensuring a stable water supply for the region.
Managed by the state of Georgia, this dam has a low hazard potential and a moderate risk assessment, indicating its importance in mitigating potential risks related to water supply and infrastructure. Although last inspected in 2012, with an inspection frequency of 5 years, the dam's condition assessment is currently labeled as "Not Rated." Despite this, the Alto Correctional Institute Water Supply Lake Dam remains a vital component of the region's water infrastructure, contributing to water security and resource management efforts in the area.
With a spillway type labeled as "Uncontrolled" and an outlet gate system also marked as "Uncontrolled," this dam relies on natural flow patterns to manage water levels and prevent overflow. While the risk assessment indicates a moderate level of risk, the overall condition of the dam is not specifically rated. As a significant water resource structure in the region, continued monitoring and maintenance of the Alto Correctional Institute Water Supply Lake Dam are essential to ensure its effectiveness in providing a reliable water supply and safeguarding against potential hazards.
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 Alto Correctional Institute Water Supply Lake Dam
Where does the data for Alto Correctional Institute Water Supply 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.
