Persimmon Creek Structure Y-21-04 Dam dam
Persimmon Creek Structure Y-21-04 Dam
The Persimmon Creek Structure Y-21-04 Dam, also known as Quattlebaum Dam, is a local government-owned earth dam located in Calhoun, Mississippi. Built in 1958 by the USDA NRCS, this dam serves as a key flood risk reduction structure on the TR-Brushy Creek. With a height of 21 feet and a storage capacity of 235 acre-feet, this dam plays a crucial role in protecting the surrounding area from potential flooding events.
Managed by the Mississippi Department of Environmental Quality, the Persimmon Creek Structure Y-21-04 Dam is state-regulated and undergoes regular inspections and enforcement measures to ensure its safety and effectiveness. Despite being categorized as having a low hazard potential, a moderate risk assessment rating of 3 indicates the importance of ongoing risk management and monitoring for this structure. With uncontrolled spillways and outlet gates, this dam serves as a vital piece of infrastructure in the region's water resource management.
For water resource and climate enthusiasts, the Persimmon Creek Structure Y-21-04 Dam provides a fascinating case study in flood risk reduction and dam management. With its unique design features and historical significance, this earth dam highlights the crucial role that local governments and regulatory agencies play in safeguarding communities from potential water-related hazards. As a part of the Vicksburg District and located in the city of Ellard, this dam stands as a testament to the importance of proactive infrastructure planning and maintenance in the face of changing climate patterns and environmental challenges.

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 Persimmon Creek Structure Y-21-04 Dam
Where does the data for Persimmon Creek Structure Y-21-04 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 Low 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.
