About this dam

White Sand - Greens Creek Str 11e Dam

White Sand - Greens Creek Str 11e Dam, also known as Whitesands Dam No. 11e, is a vital structure owned by the local government in Jefferson Davis County, Mississippi. This earth dam, with a height of 43 feet and a length of 2050 feet, was completed in 1991 by the USDA NRCS to primarily mitigate flood risks along the Unt of White Sand Creek. The dam has a storage capacity of 1235 acre-feet, serving a drainage area of 2.09 square miles.

Managed by the Mississippi Department of Environmental Quality, this dam is regulated, inspected, and enforced to ensure its continued functionality. Despite its fair condition assessment and high hazard potential, the structure meets moderate risk assessment standards. With an uncontrolled spillway and outlet gates, the dam poses a significant risk in case of emergencies, highlighting the importance of regular inspections and risk management measures to safeguard the surrounding community and water resources.

White Sand - Greens Creek Str 11e Dam stands as a critical flood risk reduction asset in Mississippi, playing a crucial role in protecting the local area from potential inundation. Its design and construction by the Natural Resources Conservation Service emphasize the importance of sustainable water resource management and climate resilience in the face of increasing environmental challenges. As water resource and climate enthusiasts, understanding the significance of infrastructure like this dam is essential in promoting effective water management practices and ensuring the safety and sustainability of our 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.

FAQ

About White Sand - Greens Creek Str 11e Dam

Where does the data for White Sand - Greens Creek Str 11e 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.
