Ozan Creek Swcd Site 20 dam
Ozan Creek Swcd Site 20
Ozan Creek SWCD Site 20, also known as Hempstead S&WCD Site 20, is a local government-owned flood risk reduction structure located in Hempstead, Arkansas. Built in 1990 by the USDA NRCS, this earth dam stands at a height of 35 feet and spans 2750 feet along the South Fork Ozan Creek. With a storage capacity of 2341 acre-feet and a drainage area of 3.2 square miles, this dam plays a crucial role in managing floodwaters and protecting the surrounding area from potential inundation.
The primary purpose of Ozan Creek SWCD Site 20 is flood risk reduction, as it helps control the flow of water during heavy rainfall events. Despite being classified as having a low hazard potential, the dam is regularly inspected by the state regulatory agency ANRC to ensure its structural integrity. With a moderate risk assessment rating of 3, this dam serves as a vital component of the local water resource management infrastructure, contributing to the overall resilience of the region against potential climate-related challenges.
Managed by the Natural Resources Conservation Service, Ozan Creek SWCD Site 20 operates with uncontrolled spillways and outlet gates, emphasizing its reliance on natural hydraulic processes. With a surface area of 77 acres and a normal storage capacity of 310 acre-feet, this dam showcases the importance of strategic water resource management in mitigating flood risks and enhancing community safety. As a key element in the Vicksburg District's water infrastructure, Ozan Creek SWCD Site 20 represents a collaborative effort between federal, state, and local agencies to safeguard the region's water resources and climate resilience.

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 20
Where does the data for Ozan Creek Swcd Site 20 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.
