Cth "E" Dike dam
Cth "E" Dike
Cth "E" Dike in Oneida, Wisconsin, is a crucial structure with a primary purpose of hydroelectric power generation and flood risk reduction along the Wisconsin River. Completed in 1935, this earth dam stands at 24 feet tall and stretches 1650 feet in length, providing storage for up to 46,006 acre-feet of water. Managed by the Federal Energy Regulatory Commission, this high-hazard potential dam has a maximum discharge capacity of 32,500 cubic feet per second, highlighting its significance in water resource management and climate resilience efforts.
Despite its age, the condition assessment of Cth "E" Dike is currently listed as "Not Available," necessitating further inspections and risk management measures to ensure its structural integrity and operational efficiency. The dam has been associated with four other structures and is under state jurisdiction with permitting and enforcement responsibilities. The high risk level of this dam underscores the importance of having emergency action plans in place and regular assessments to mitigate potential hazards and protect downstream communities and ecosystems in case of emergencies.
As water resource and climate enthusiasts, understanding the critical role of infrastructure like Cth "E" Dike in managing water resources, generating clean energy, and reducing flood risks is essential. By staying informed about the condition, risks, and management measures associated with dams like Cth "E" Dike, enthusiasts can contribute to sustainable water management practices and climate adaptation strategies to safeguard our environment for future generations.
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 Cth "E" Dike
Where does the data for Cth "E" 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.
