Summary
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
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
