French And Sacia dam
French And Sacia
French and Sacia is a private dam located in Trempealeau, Wisconsin, specifically in Galesville. Built in 1972 by the USDA NRCS, this earth dam stands at a height of 24 feet and has a hydraulic height of 13 feet. Its primary purpose is for fire protection, stock, or as a small fish pond, with a storage capacity of 60 acre-feet and a surface area of 4 acres. The dam is regulated by the Wisconsin Department of Natural Resources and undergoes regular inspections.
Despite its age, French and Sacia is in poor condition and has been assessed with a significant hazard potential. The dam's risk assessment is classified as very high, emphasizing the importance of proper risk management measures. In the event of an emergency, there are no detailed plans or contacts readily available, highlighting the need for an updated emergency action plan. With a drainage area of 0.7 square miles and a maximum discharge of 280 cubic feet per second, the dam plays a crucial role in water resource management in the region.
Water resource and climate enthusiasts should take note of French and Sacia as a key infrastructure in the area. Its state-regulated status, coupled with its poor condition and high hazard potential, underscores the importance of effective risk management and emergency preparedness. As one of the essential structures for fire protection and water storage, the dam's significance in the local ecosystem cannot be understated. Further monitoring and maintenance efforts are crucial to ensuring the safety and functionality of French and Sacia for years to come.

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 French And Sacia
Where does the data for French And Sacia 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.
