Sawyer Dike dam
Sawyer Dike
Sawyer Dike, located in Oneida, Wisconsin, along the Wisconsin River, is a vital structure designed for flood risk reduction and hydroelectric power generation. Built in 1935, this earth dam stands at a height of 20 feet and stretches over 800 feet in length. Managed by the Federal Energy Regulatory Commission, Sawyer Dike plays a crucial role in regulating water flow and mitigating flood hazards in the region.
With a maximum storage capacity of 46,006 acre-feet and a maximum discharge of 32,500 cubic feet per second, Sawyer Dike is equipped to handle high-risk scenarios. Despite its age, the dam's hazard potential is classified as high, highlighting the importance of regular inspections and risk management measures. While its condition assessment is currently not available, Sawyer Dike remains a key infrastructure for water resource management in Wisconsin.
As a public utility structure, Sawyer Dike serves both practical and environmental purposes, showcasing the intersection of water resource management and climate resilience. Its presence not only helps in flood control but also contributes to sustainable energy production through hydroelectric power generation. With its strategic location and design features, Sawyer Dike stands as a testament to the ongoing efforts to balance water resource management and climate adaptation in the face of changing environmental 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 Sawyer Dike
Where does the data for Sawyer 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.
