Ozan Creek Swcd Site 11 dam
Ozan Creek Swcd Site 11
Ozan Creek SWCD Site 11, located in Hempstead County, Arkansas, is a flood risk reduction structure designed by the USDA NRCS and completed in 1995. This earth dam, with a height of 39.8 feet and a length of 1335 feet, serves to protect the surrounding area from potential flooding by the South Fork Ozan Creek. With a normal storage capacity of 170 acre-feet and a maximum discharge of 1116 cubic feet per second, the dam plays a critical role in managing water flow and reducing flood risks in the region.
Managed by local government authorities and regulated by the Arkansas Natural Resources Commission (ANRC), Ozan Creek SWCD Site 11 has a moderate risk rating and a low hazard potential. While the dam's condition assessment is not rated, it is subject to state inspections, enforcement, and permitting to ensure its continued safety and effectiveness. The structure features an uncontrolled spillway and outlet gates, highlighting its reliance on natural water flow mechanisms for flood management. With a focus on flood risk reduction as its primary purpose, this dam serves as a vital infrastructure asset in the region's water resource and climate resilience efforts.
Despite its low hazard potential, Ozan Creek SWCD Site 11 plays a crucial role in safeguarding the local community from potential flooding events. With its strategic location along the South Fork Ozan Creek and sophisticated design by the USDA NRCS, this earth dam stands as a testament to effective water resource management and climate adaptation practices. As state-regulated infrastructure, its maintenance and operation underscore the importance of proactive risk management measures in ensuring the safety and resilience of water systems in the face of changing climate conditions.
Dam data reference
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 Ozan Creek Swcd Site 11
Where does the data for Ozan Creek Swcd Site 11 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.
