Summary

The flowage, completed in 1971, serves a primary purpose of "Other" and is classified as an Earth dam with a height of 9 feet and a hydraulic height of 7 feet. With a storage capacity of 467 acre-feet and a surface area of 75.5 acres, Shoulder Creek Flowage plays a crucial role in the management of water resources in the region.

Despite being assessed as having a low hazard potential and fair condition, Shoulder Creek Flowage is considered to have a very high risk level, indicating the importance of ongoing monitoring and management. The controlled spillway system with a width of 35 feet helps regulate water levels, with a maximum discharge capacity of 289 cubic feet per second. The flowage area covers 4.89 square miles and is situated in a picturesque location, offering opportunities for outdoor recreation and wildlife habitat conservation.

Overall, Shoulder Creek Flowage represents a significant water resource in Wisconsin, contributing to flood control, water storage, and ecosystem preservation. With its state-regulated status and ongoing inspections, the flowage underscores the importance of sustainable water management practices in the face of changing climate conditions. Enthusiasts of water resources and climate science can appreciate the role that Shoulder Creek Flowage plays in maintaining the ecological balance of the region and supporting the well-being of local communities.

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. 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

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, 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.
