Owensby Number One Dam dam
Owensby Number One Dam
Owensby Number One Dam, located in Marengo, Alabama, is a privately owned structure primarily used for recreation purposes. Completed in 1972, this earth dam stands at a structural height of 28 feet and a hydraulic height of 22 feet, providing a maximum storage capacity of 62 acre-feet. The dam is situated on TR-Sycamore Creek, within the jurisdiction of the Mobile District of the US Army Corps of Engineers.
With a significant hazard potential, Owensby Number One Dam has not been rated for its condition assessment. Despite its age, the dam remains in operation without any state regulation, inspection, or enforcement. The surrounding area offers recreational opportunities, making this dam a valuable asset for water resource and climate enthusiasts interested in exploring the diverse landscapes of Alabama.
While Owensby Number One Dam may not have a designated emergency action plan or regularly updated hazard assessments, its presence on TR-Sycamore Creek serves as a reminder of the importance of responsible dam management and maintenance in the face of changing climate patterns. As climate enthusiasts continue to monitor water resources in the region, this dam offers a unique opportunity to observe the intersection of human infrastructure and natural ecosystems in a dynamic and evolving environment.

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.
Plan around the weather

About Owensby Number One Dam
Where does the data for Owensby Number One 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 Significant 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.
