Summary
This earth dam stands at a height of 8.5 feet with a hydraulic height of 7 feet and a structural height of 8.5 feet. With a maximum discharge capacity of 55 cubic feet per second, the dam has a low hazard potential and a moderate risk assessment rating of 3.
The dam has a normal storage capacity of 35 acre-feet and a maximum storage of 112 acre-feet, serving a drainage area of 0.8 square miles. The spillway type is uncontrolled with a width of 15 feet. Although the dam has not been rated for its condition assessment, it undergoes inspections every 5 years with the last one conducted in August 2006. Despite its low hazard potential, the risk assessment of Friday Flooding remains moderate, highlighting the importance of continued monitoring and risk management measures to ensure the safety of the surrounding area and water resources.
Located in Delta County, Michigan, Friday Flooding's proximity to the Elm Creek tributary and its 400-foot dam length make it a crucial structure for water management in the region. With its recreational primary purpose, the dam provides not only leisure activities but also contributes to the overall water storage and management system in the area. As water resource and climate enthusiasts, understanding the details of Friday Flooding allows for a deeper appreciation of the complexities involved in managing our water infrastructure and the importance of sustainable practices to mitigate potential risks associated with dams like this one.

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.
