Ascalmore Structure Yo-30-15 Dam dam
Ascalmore Structure Yo-30-15 Dam
Ascalmore Structure Yo-30-15 Dam, also known as Owens Dam, is a local government-owned structure located in Paynes, Mississippi. Built in 1956 by the USDA NRCS, this earth dam stands at a height of 22 feet and serves the primary purpose of flood risk reduction along Powers Creek. With a storage capacity of 62 acre-feet, the dam is regulated and inspected by the Mississippi Department of Environmental Quality to ensure its safety and functionality.
The dam has a low hazard potential and a moderate risk assessment, indicating a need for ongoing monitoring and management measures. While it currently has uncontrolled spillways and outlet gates, the structure has not been rated for its condition assessment. Despite its age, the Ascalmore Structure Yo-30-15 Dam plays a crucial role in protecting the surrounding area from flooding events and highlights the importance of proper water resource management in mitigating climate-related risks.
As water resource and climate enthusiasts, understanding the infrastructure and functionality of dams like Ascalmore Structure Yo-30-15 Dam is essential for addressing the challenges posed by a changing climate. By staying informed about the regulatory agencies involved, the design and purpose of the dam, and its risk assessment, we can advocate for sustainable water management practices that protect both communities and ecosystems in the face of increasing environmental uncertainties.

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 Ascalmore Structure Yo-30-15 Dam
Where does the data for Ascalmore Structure Yo-30-15 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.
