Tilleda dam
Tilleda
Tilleda, located in Shawano, Wisconsin, is a gravity dam on the North Branch Embarrass River completed in 1910 for recreational purposes. It stands at 17 feet tall with a hydraulic height of 15 feet and a length of 82 feet, holding a storage capacity of 160 acre-feet. The dam's hazard potential is classified as high, with a very high risk assessment rating.
Despite its age, Tilleda's condition was assessed as satisfactory during the last inspection in September 2019, with inspections occurring every two years. The dam is regulated by the Wisconsin Department of Natural Resources, ensuring proper permitting, inspection, and enforcement. The surrounding area covers 28 acres with a drainage area of 70.5 square miles, making it a vital component of both water resource management and recreational activities in the region.
As a significant structure in the area, Tilleda plays a crucial role in managing water resources and providing recreational opportunities. With its historical significance and ongoing regulatory oversight, the dam continues to serve its purpose effectively while maintaining a high level of public safety. For water resource and climate enthusiasts, Tilleda represents a blend of engineering ingenuity, environmental stewardship, and recreational enjoyment in the heart of Wisconsin.

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 Tilleda
Where does the data for Tilleda 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.
