Hill Lake Dam dam
Hill Lake Dam
Hill Lake Dam, also known as Denton Lake Dam, is a privately-owned structure located in Douglasville, Georgia. Built in 1982, this earth dam stands at a height of 21.4 feet and serves primarily for recreational purposes. With a storage capacity of 288 acre-feet and a surface area of 23 acres, Hill Lake Dam provides a serene environment for water resource and climate enthusiasts to enjoy various outdoor activities.
Despite being unregulated by the state, Hill Lake Dam has a low hazard potential and is classified as having a moderate risk level. The dam features uncontrolled spillways and outlets, with no associated locks or gates. While its condition assessment remains unrated, the dam's risk management measures are not specified, and emergency action plans have not been reported or reviewed in recent years. With its picturesque surroundings and moderate risk level, Hill Lake Dam offers a unique opportunity for water resource enthusiasts to explore and appreciate the intersection of natural beauty and man-made infrastructure.
Located in Paulding County, Georgia, Hill Lake Dam is part of the Mobile District and is represented by Tom Graves (R) in Congress. The dam's primary purpose is for recreation, providing a tranquil setting for visitors to enjoy the outdoors. With its unknown designer and foundations, Hill Lake Dam offers a fascinating glimpse into the intersection of human ingenuity and environmental stewardship, making it a captivating destination for those interested in water resources and climate dynamics.

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 Hill Lake Dam
Where does the data for Hill 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.
