Flood Water Retarding Structure Site 30 dam
Flood Water Retarding Structure Site 30
Flood Water Retarding Structure Site 30, also known as Fwrs #30, is a Federal-owned structure located in Holmes County, Mississippi. Completed in 2001 by the US Army Corps of Engineers, this Earth-type dam stands at a height of 42 feet and has a maximum storage capacity of 3993 acre-feet. With a primary purpose of flood risk reduction, it plays a crucial role in managing water levels along the Black Creek-TR stream and protecting the surrounding area from potential flooding events.
The dam is equipped with an uncontrolled spillway measuring 200 feet in width to manage excess water flow and prevent overtopping during high-volume discharge events. Regular inspections and maintenance efforts are conducted by the US Army Corps of Engineers to ensure the structural integrity of the dam and mitigate any potential hazards. In the event of an emergency, an Emergency Action Plan (EAP) is in place, meeting guidelines and updated periodically to address any risks associated with the dam and facilitate coordinated responses with local emergency management agencies.
Overall, Flood Water Retarding Structure Site 30 serves as a critical infrastructure asset in the region, providing flood protection and water management capabilities to safeguard the community against potential risks. Through proactive risk management measures, continuous monitoring, and public engagement efforts, the US Army Corps of Engineers is committed to ensuring the safety and resilience of the dam, enhancing preparedness, and response capabilities in the face of potential dam-related emergencies.

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 Flood Water Retarding Structure Site 30
Where does the data for Flood Water Retarding Structure Site 30 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 Significant 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.
