Immanuel Dam dam
Immanuel Dam
Immanuel Dam, also known as Arnoname 212, is a privately owned structure located in Sebastian County, Arkansas. 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
- 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.
- 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.
- 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.
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, environmental 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.

About Immanuel Dam
Where does the data for Immanuel Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
