Summary
Built in 1965 by the USDA NRCS, this Earth-type dam serves the primary purpose of creating a Fish and Wildlife Pond along the Messiah Rill. With a height of 26 feet and a length of 441 feet, Immanuel Dam has a storage capacity of 110 acre-feet and covers a surface area of 10 acres.
Despite being classified as having a significant hazard potential, the dam's condition assessment is currently listed as "Not Rated." While it is regulated and inspected by the Arkansas Natural Resources Commission, details regarding its emergency action plan, risk assessment, and management measures are not readily available. The last inspection of Immanuel Dam took place in June 2011, and it is located in the jurisdiction of the Tulsa District of the US Army Corps of Engineers.
For water resource and climate enthusiasts, Immanuel Dam presents an intriguing case study in the management of small-scale water infrastructure for agricultural and ecological purposes. As a vital resource for fish and wildlife in the area, the dam's role in conservation and fire protection highlights the intersection of human development and environmental stewardship. With its unique design and historical significance, Immanuel Dam stands as a testament to the ongoing efforts to balance the needs of communities with the preservation of natural resources in the face of changing climate conditions.

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.
