About this dam

Hartley Lake Dam

Hartley Lake Dam, located in Crawford, Georgia, was completed in 1970 and serves as a recreational site with a primary purpose of providing leisure activities for visitors. This earth dam stands at a height of 22.4 feet and has a hydraulic height of 21.8 feet, creating a storage capacity of 141 acre-feet. With a surface area of 9.5 acres, the dam is surrounded by a drainage area of 16 square miles, making it a serene spot for water resource and climate enthusiasts to explore.

Managed by a private owner, Hartley Lake Dam has a low hazard potential and is currently assessed as being in "Not Rated" condition. Despite not being state-regulated, the dam is subject to regular inspections, with the last one conducted in August 2015. The risk assessment for this structure is moderate, highlighting the importance of continued monitoring and maintenance to ensure its safety and longevity. As a key part of the local landscape, the dam offers a unique opportunity for individuals interested in water resource management to appreciate the intersection of human infrastructure and natural ecosystems.

With its tranquil setting and recreational offerings, Hartley Lake Dam presents a captivating blend of human ingenuity and environmental stewardship. As water resource and climate enthusiasts explore this site in Knoxville, Georgia, they are invited to consider the balance between human activity and ecological impact. By engaging with the history and design of the dam, visitors can deepen their understanding of the interconnectedness of water management and climate resilience. Hartley Lake Dam stands as a testament to the ongoing dialogue between human needs and environmental sustainability, providing a rich backdrop for further exploration and reflection.

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 Hartley Lake Dam

Where does the data for Hartley 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.
