Summary
Completed in 1986, this earth dam stands at a height of 22.2 feet and spans a length of 600 feet, with a capacity to hold up to 80 acre-feet of water. The dam is situated on the TR-Tombigbee River, within the jurisdiction of the Mobile District and Congressional District 07, Alabama.
With a low hazard potential and a moderate risk assessment rating, the Will Haas dam serves as a vital resource for wildlife habitat and recreational activities in the area. Despite not being state regulated or permitted, the dam provides a safe environment for the local community to enjoy outdoor activities such as fishing and wildlife observation. The structure has not been rated for its current condition, but it continues to support the ecosystem of the surrounding area.
For water resource and climate enthusiasts, the Will Haas dam offers a glimpse into the importance of private infrastructure in supporting conservation efforts and recreational opportunities. The dam's construction by the Natural Resources Conservation Service showcases a collaborative approach to managing water resources for the benefit of both wildlife and local communities. As an integral part of the landscape along the TR-Tombigbee River, the Will Haas dam represents a harmonious balance between human intervention and environmental stewardship in the dynamic ecosystem of Alabama.

Dam Data Reference
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.
