Carroll Horn Dam dam
Carroll Horn Dam
Carroll Horn Dam, located in Simpson, Mississippi, is a private dam primarily used for recreation purposes. Standing at a height of 23 feet and with a length of 369 feet, this earth dam holds a storage capacity of 83 acre-feet of water from the UNT of Goodwater Creek. The dam features an uncontrolled spillway and has a surface area of 8 acres, serving as a popular spot for outdoor enthusiasts in the area.
Managed by the Mississippi Department of Environmental Quality, Carroll Horn Dam is subject to state regulations, inspections, and enforcement to ensure its safety and compliance with environmental standards. While the dam's hazard potential is currently listed as undetermined and its condition assessment is not rated, it falls under a moderate risk category according to the available data. Although the exact year of completion and last inspection date are not provided, the dam continues to offer recreational opportunities and contribute to the local ecosystem in the region.
With its strategic location and essential role in water management for the area, Carroll Horn Dam stands as a vital infrastructure piece in the Vicksburg District. As water resource and climate enthusiasts explore the significance of dams in the region, this earth dam serves as a tangible example of human efforts to harness and utilize natural water resources for recreational and environmental purposes. As its risk management measures are developed and assessed, Carroll Horn Dam remains a focal point for understanding the intersection of water conservation and public safety in Mississippi.

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 Carroll Horn Dam
Where does the data for Carroll Horn 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 Undetermined 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.
