Gallagher Flowage Controls dam
Gallagher Flowage Controls
Located in Wood County, Wisconsin, Gallagher Flowage Controls is a state-owned structure regulating the flow of Kert Creek Ditch No. 1. Built in 1969 for recreation purposes, this earth dam stands at a height of 10 feet with a hydraulic height of 7 feet. With a storage capacity of 1,170 acre-feet and a drainage area of 16 square miles, Gallagher Flowage Controls covers a surface area of 700 acres and boasts a maximum discharge capacity of 200 cubic feet per second.
Despite its age, Gallagher Flowage Controls maintains a fair condition assessment and a low hazard potential. Regular inspections are conducted every 10 years, with the last inspection occurring in October 2014. The structure is regulated, permitted, and inspected by the Wisconsin Department of Natural Resources, ensuring its safety and compliance with state standards. Although the risk assessment indicates a moderate level of risk, the structure has not been assigned a Dam Safety Action Classification (DSAC) date, suggesting that risk management measures are under control.
Overall, Gallagher Flowage Controls serves as a vital asset for both water resource management and recreational activities in the area. With its consistent regulatory oversight and fair condition, this structure continues to provide essential functions while ensuring the safety of surrounding communities and the environment. As a prime example of effective state-owned infrastructure, Gallagher Flowage Controls stands as a testament to the importance of proper maintenance and oversight in preserving water resources 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 Gallagher Flowage Controls
Where does the data for Gallagher Flowage Controls 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.
