Tidwell Dam dam
Tidwell Dam
Tidwell Dam, located in Vicksburg, Mississippi, is a privately owned structure that serves primarily for recreation purposes. This earthen dam, with a height of 25 feet and a length of 570 feet, impounds Redbone Creek, providing a storage capacity of 125 acre-feet. Despite its relatively small size, the dam poses a high hazard potential and has been assessed as unsatisfactory in condition.
The dam is regulated by the Mississippi Department of Environmental Quality, with state permitting, inspection, and enforcement processes in place. The last inspection in April 2018 revealed the dam's unsatisfactory condition, prompting the need for continued monitoring and potential risk management measures. With a moderate risk assessment rating, stakeholders and local officials must remain vigilant in ensuring the dam's safety and functionality to protect downstream communities and the surrounding environment.
As climate change impacts water resources and infrastructure, dams like Tidwell Dam play a crucial role in managing water flow and providing recreational opportunities. The presence of an uncontrolled spillway and the dam's proximity to residential areas underscore the importance of regular inspections, emergency preparedness, and risk mitigation strategies. Tidwell Dam serves as a reminder of the ongoing challenges faced in maintaining and safeguarding our water resources in the face of changing climatic conditions.

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 Tidwell Dam
Where does the data for Tidwell 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.
