Summary

Situated on a tributary of the Ohatchee Creek, this dam has a hydraulic height of 17 feet and a structural height of 20 feet. With a normal storage capacity of 45 acre-feet and a maximum storage of 70 acre-feet, Thrasher Dam offers a serene and picturesque setting for water resource and climate enthusiasts to enjoy various recreational activities.

Despite being classified as having a low hazard potential and not yet rated for its condition assessment, Thrasher Dam remains a popular spot for outdoor enthusiasts. The dam spans 275 feet in length and has a maximum discharge capacity of 340 cubic feet per second, ensuring a steady flow of water for its designated purposes. The dam's surrounding area has not been assessed for inundation risks, emergency action plans, or risk management measures, but its tranquil waters and scenic views continue to attract visitors seeking a peaceful retreat in nature.

Owned by a private entity and located within the jurisdiction of the Mobile District of the US Army Corps of Engineers, Thrasher Dam stands as a testament to the harmonious fusion of human engineering and natural beauty. While lacking in certain regulatory assessments and emergency preparedness measures, the dam's role in providing recreational opportunities and preserving the local ecosystem underscores its significance in the region's water resource management. For water resource and climate enthusiasts, Thrasher Dam represents a captivating destination where the allure of nature meets the ingenuity of human design.

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. 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

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, 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.
