Summary
Completed in 1977, this earth dam stands at 20 feet high and spans 900 feet in length, with a storage capacity of 150 acre-feet. The dam's primary purpose is flood risk reduction, with a spillway width of 1 foot and a maximum discharge of 1,160 cubic feet per second.
Managed by the Oklahoma Water Resources Board, Acker Eric has a low hazard potential and a very high risk assessment rating. While the dam is currently rated as "Not Rated" in terms of condition assessment, it undergoes inspection every 5 years, with the last inspection date recorded in August 2011. The dam is equipped with a single valve outlet gate and is regulated, permitted, inspected, and enforced by state authorities, ensuring its continued safety and functionality for the surrounding community.
Acker Eric serves as a vital infrastructure for mitigating flood risks in Hughes County, Oklahoma, under the oversight of the Natural Resources Conservation Service. With its strategic location and design, this dam plays a crucial role in protecting the local area from potential flooding events, highlighting the importance of sustainable water resource management and climate resilience in the region.

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.
