Dean Griner Lake Dam dam
Dean Griner Lake Dam
Dean Griner Lake Dam in Mississippi is a private-owned structure regulated by the state's Department of Environmental Quality. This earth dam, with a buttress core type, stands at a height of 24 feet and has a storage capacity of 330 acre-feet. The primary purpose of the dam is for recreation, providing opportunities for water enthusiasts to enjoy various activities in the area.
Located in Jefferson Davis County, this dam serves as a vital resource for the community, offering opportunities for boating, fishing, and other water-related activities. Despite the moderate risk assessment, with an undetermined hazard potential, the dam adds to the beauty and functionality of the region. The dam's uncontrolled spillway and its presence in the New Orleans District highlight the importance of maintaining and monitoring its condition to ensure safety and longevity for all who benefit from its presence.
As a notable feature in the water resource and climate landscape, Dean Griner Lake Dam represents a balance between recreational enjoyment and environmental responsibility. Ensuring its proper upkeep and adherence to state regulations is crucial for preserving its function and minimizing any potential risks. For water resource and climate enthusiasts, understanding the significance of structures like Dean Griner Lake Dam showcases the intersection of human activity with natural resources in a sustainable and responsible manner.

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.
Plan around the weather

About Dean Griner Lake Dam
Where does the data for Dean Griner 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 Undetermined 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.
