Summary

The earth dam stands at 8 feet tall with a hydraulic height of 5.5 feet, creating a reservoir with a storage capacity of 50 acre-feet. Despite its low hazard potential and satisfactory condition, the dam has not been inspected since June 2001, with an inspection frequency of 5 years.

Situated on Big Stone Creek, the dam's uncontrolled spillway is 6 feet wide, allowing for safe overflow during periods of high water. While the risk assessment for Goose Pond Dam is moderate, with a DSAC assigned date yet to be determined, the structure's primary purpose remains focused on providing recreational opportunities for visitors. The dam's location in Emmet County, Michigan, offers a picturesque setting for outdoor enthusiasts and water resource aficionados alike.

As one of the many dams managed by the Detroit District of the US Army Corps of Engineers, Goose Pond Dam plays a crucial role in regulating water levels and providing a habitat for local wildlife. With its strategic position within the watershed and its impact on the surrounding environment, the dam stands as a testament to the intersection of water resource management and climate resilience in the Great Lakes region.

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.
