Summary
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
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
