About this dam

Lake Dow North Dam

Lake Dow North Dam in Henry, Georgia, is a private earth dam completed in 1989 with a primary purpose of recreation. Standing at a height of 42 feet and stretching 570 feet in length, this dam holds a maximum storage capacity of 2047 acre-feet, with a normal storage level of 1543 acre-feet. The dam overlooks Nails Creek and covers a surface area of 93 acres, providing a serene and picturesque setting for water resource and climate enthusiasts.

Despite being classified as having a low hazard potential, Lake Dow North Dam is subject to state jurisdiction and inspection, ensuring its structural integrity and safety. The dam's uncontrolled spillway and outlet gates contribute to its recreational appeal, while its risk assessment indicates a moderate level of risk. Although the condition assessment is currently not rated, the dam's last inspection in January 2016 suggests a commitment to regular monitoring and maintenance to uphold its functionality and safety for visitors and the surrounding environment.

With its tranquil surroundings and essential role in providing recreational opportunities, Lake Dow North Dam stands as a testament to human ingenuity and the harmonious coexistence of water resources with the natural landscape. Enthusiasts of water resources and climate will find this dam to be a captivating destination that showcases the delicate balance between human intervention and environmental stewardship, making it a must-visit site for those passionate about sustainable water management practices.

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.

FAQ

About Lake Dow North Dam

Where does the data for Lake Dow North 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.
