About this dam

Marshall Lord Lake

Marshall Lord Lake, located in Laurens, Georgia, is a private irrigation reservoir completed in 1950 with a dam height of 12 feet and a length of 336 feet. This earth dam serves the primary purpose of irrigation, with a storage capacity of 91 acre-feet and a normal storage level of 36 acre-feet. The reservoir covers a surface area of 10 acres and drains an area of 860 acres, providing water for agricultural needs in the region.

Despite being privately owned and not regulated by the state, Marshall Lord Lake has a low hazard potential and a moderate risk assessment rating. The dam is classified as uncontrolled spillway type with uncontrolled outlet gates. While the condition assessment is not rated and there are no inspection records available, the reservoir still plays a crucial role in providing water for irrigation purposes in the area. The risk management measures and emergency preparedness for the dam are currently unknown, highlighting the need for further evaluation and potential improvements to ensure its long-term safety and functionality for water resource and climate enthusiasts in the region.

Overall, Marshall Lord Lake stands as a historic water resource infrastructure in Georgia, serving the local community with its irrigation capabilities. As an earth dam with a modest storage capacity, the reservoir contributes to the agricultural productivity of the area. While its risk assessment indicates moderate risk, the exact measures in place for risk management and emergency response remain unclear. Continued monitoring and maintenance of Marshall Lord Lake will be essential to ensure its sustainability and effectiveness in meeting the water needs of the region amidst changing climate conditions.

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 Marshall Lord Lake

Where does the data for Marshall Lord Lake 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.
