Hidden Lake Dam dam
Hidden Lake Dam
Hidden Lake Dam in Lumpkin, Georgia, stands as a testament to the importance of water resource management and climate resilience. Built in 1940 by designer PARKER, this private dam mainly serves a recreational purpose, offering a tranquil oasis for visitors to enjoy. With a height of 35 feet and a length of 200 feet, Hidden Lake Dam has a storage capacity of 94 acre-feet, providing a vital source of water for the surrounding area.
Despite its low hazard potential, Hidden Lake Dam is subject to regular inspections to ensure its structural integrity and safety. The dam, made of earth and buttress core types, features an uncontrolled spillway and outlet gates. The risk assessment for the dam is moderate (3), highlighting the need for ongoing risk management measures to mitigate potential threats and ensure the continued functionality of this essential water resource.
Located within the Mobile District of the US Army Corps of Engineers, Hidden Lake Dam is a key component of the region's water infrastructure. While not federally owned or funded, the dam plays a crucial role in water storage and management for recreational purposes. With its serene surroundings and important water storage capacity, Hidden Lake Dam serves as a valuable resource for both locals and visitors alike, highlighting the intersection of water resources, climate resilience, and recreational opportunities.
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 Hidden Lake Dam
Where does the data for Hidden 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.
