Summary
Built in 1970 by the USDA NRCS, this Earth dam stands at a height of 24 feet and stretches 450 feet in length. With a storage capacity of 95 acre-feet and a drainage area of 0.26 square miles, the dam serves as a habitat for various aquatic species in the area.
Despite its low hazard potential and moderate risk assessment rating, J B Acker currently has a "Not Rated" condition assessment. The dam features an uncontrolled spillway with a width of 44 feet, allowing for a maximum discharge of 170 cubic feet per second. While it does not fall under the jurisdiction of state regulatory agencies, the maintenance and safety of the structure are crucial for the surrounding environment and community.
Although the dam has not been inspected recently and lacks an Emergency Action Plan, its importance for fish and wildlife preservation in the region cannot be understated. With its picturesque location along the Sipsey River and contributions to the local ecosystem, J B Acker remains an essential resource for water and climate enthusiasts alike.

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.
