Big Rock Creek Farm dam
Big Rock Creek Farm
Nestled in the picturesque countryside of St. Croix Falls, Wisconsin, Big Rock Creek Farm serves as a vital water resource for the area. This private-owned dam, known as Big Rock Creek, stands as a gravity structure with a height of 20 feet and a storage capacity of 50 acre-feet. Primarily used for fire protection, stock, and small fish pond purposes, the dam plays a crucial role in maintaining water supply and supporting local ecosystems.
Managed by the Wisconsin Department of Natural Resources, this dam is subject to state regulation, inspection, and enforcement to ensure its structural integrity and safety. Despite being classified as having a low hazard potential, the condition assessment of Big Rock Creek Farm's dam is rated as fair, with a risk assessment indicating very high risk. The dam has a controlled spillway type and a maximum discharge capacity of 1250 cubic feet per second, emphasizing its importance in flood control and water management in the region.
With its serene location, essential functions, and regulatory oversight, Big Rock Creek Farm stands as a significant water resource and infrastructure that not only supports the local community's needs but also plays a crucial role in water conservation, climate resilience, and environmental protection efforts in Wisconsin.
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 Big Rock Creek Farm
Where does the data for Big Rock Creek Farm 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 Low 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.
