White Cypress Lake Dam dam
White Cypress Lake Dam
White Cypress Lake Dam, also known as Lake Cypress Dam, is a private dam located in Necaise, Hancock County, Mississippi. Completed in 1972, this Earth dam stands at a height of 26.59 feet and serves the primary purpose of recreation. With a normal storage capacity of 1174.42 acre-feet and a maximum storage of 2238.5 acre-feet, the dam plays a crucial role in providing water resources for recreational activities in the area.
Managed by the Mississippi Department of Environmental Quality, the White Cypress Lake Dam is regulated, inspected, and permitted by state authorities to ensure its safety and compliance with environmental standards. The dam's spillway, with a width of 4 feet, is uncontrolled, and it has a high hazard potential rating. Despite being assessed as in fair condition during the last inspection in January 2021, the dam is subject to moderate risk, highlighting the importance of ongoing risk management measures to safeguard the surrounding community and environment.
For water resource and climate enthusiasts, White Cypress Lake Dam offers a fascinating case study in dam infrastructure management and recreational water use. Its location on the UNT of White Cypress Creek, under the jurisdiction of the Mobile District of the US Army Corps of Engineers, presents opportunities for exploring the intersection of water conservation, recreation, and regulatory oversight. As efforts continue to monitor and improve the dam's safety and resilience, it exemplifies the crucial role that dams play in balancing water resource management with environmental protection and public recreation.

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 White Cypress Lake Dam
Where does the data for White Cypress 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 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.
