Jim Hall Dike dam
Jim Hall Dike
Jim Hall Dike, located in Oneida, Wisconsin, along the Wisconsin River, was completed in 1935 and serves as a crucial structure for flood risk reduction and hydroelectric power generation. This earth dam stands at a height of 22 feet and stretches 1550 feet in length, providing a storage capacity of 46,006 acre-feet. Its primary purpose is hydroelectric, with the Federal Energy Regulatory Commission overseeing its operations and regulatory requirements.
Despite its age, Jim Hall Dike remains a vital component of water resource management in the region, with a high hazard potential due to its location and function. While the condition assessment is not currently available, the dam undergoes regular inspections by the Federal Energy Regulatory Commission to ensure its structural integrity and safety. The associated structures, including WI00775S001, WI00775S002, and WI00775S003, contribute to the overall effectiveness of the dike in managing the flow of the Wisconsin River.
As climate change impacts continue to be felt across the country, the role of structures like Jim Hall Dike becomes increasingly important in mitigating flood risks and harnessing renewable energy sources. With its historical significance and ongoing operational relevance, the dike stands as a testament to the intersection of water resource management, climate adaptation, and sustainable energy production in the Midwest region.
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 Jim Hall Dike
Where does the data for Jim Hall Dike 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 High 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.
