Lake Ruby Dam dam
Lake Ruby Dam
Lake Ruby Dam, located in Pelahatchie, Mississippi, was completed in 2008 and serves as a vital recreational resource for the community. The dam, primarily made of earth and stone, stands at a height of 28 feet and has a storage capacity of 1277 acre-feet. With a surface area of 83.3 acres and a drainage area of 0.79 square miles, the dam plays a crucial role in managing water flow and providing opportunities for outdoor activities like fishing and boating.
Despite being privately owned, Lake Ruby Dam is regulated by the Mississippi Department of Environmental Quality, ensuring that the structure meets necessary safety standards. The dam has a high hazard potential, but a recent assessment deemed its condition as fair. Regular inspections are conducted to monitor its safety, with the last assessment taking place in February 2021. While the dam poses a moderate risk, appropriate risk management measures are in place to mitigate any potential issues and ensure the safety of surrounding communities.
With its picturesque surroundings and recreational offerings, Lake Ruby Dam stands as a testament to the importance of water resource management in maintaining a balance between human enjoyment and environmental conservation. Climate and water resource enthusiasts will find this dam a fascinating example of how infrastructure can harmoniously coexist with nature while serving the needs of local communities.

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 Lake Ruby Dam
Where does the data for Lake Ruby 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 High 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.
