Black Creek Watershed Number 100 Dam dam
Black Creek Watershed Number 100 Dam
Located in Holmes, Mississippi, the Black Creek Watershed Number 100 Dam stands as a critical structure designed by the USDA NRCS in 1996 for flood risk reduction along the Black Creek. With a height of 39 feet and a length of 900 feet, the dam provides a maximum storage capacity of 451 acre-feet and a normal storage of 122 acre-feet, offering protection to the surrounding area from potential flooding events.
Managed by the Mississippi Department of Environmental Quality, the dam is regularly inspected and enforced to ensure its structural integrity and safety. Despite its high hazard potential, the dam is currently in satisfactory condition, meeting regulatory guidelines and posing a moderate risk. The dam's uncontrolled spillway type and lack of outlet gates highlight the importance of continuous monitoring and risk management measures to mitigate potential disasters and safeguard the local community.
As a vital component of the Vicksburg District's water resource infrastructure, the Black Creek Watershed Number 100 Dam serves as a testament to the collaborative efforts of local government agencies in enhancing flood resilience and protecting the environment. With its strategic location and impact on the surrounding ecosystem, the dam underscores the importance of sustainable water resource management practices in mitigating the effects of climate change and ensuring the long-term safety and well-being of the community.

About Black Creek Watershed Number 100 Dam
Where does the data for Black Creek Watershed Number 100 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 below 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.

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.
