Summary
This private dam, completed in 1907, serves a primary purpose of recreation, offering a serene environment for water enthusiasts and outdoor lovers. With a height of 20 feet and a length of 210 feet, Tecumseh Dam has a storage capacity of 865 acre-feet and a normal storage of 265 acre-feet, providing vital water resources for the surrounding area.
Managed by the Michigan Department of Environment, Great Lakes, and Energy, Tecumseh Dam is regulated, inspected, and enforced for safety and compliance. Its controlled spillway, with a width of 104 feet, helps manage water flow during high discharge events. Despite having a significant hazard potential, the dam is currently assessed to be in fair condition, with regular inspections scheduled every four years to ensure its structural integrity and safety.
Located within the Buffalo District, Tecumseh Dam poses a very high risk according to its risk assessment, emphasizing the importance of effective risk management measures. As a popular spot for recreational activities, the dam plays a crucial role in providing water resources for the community while also highlighting the need for ongoing monitoring and maintenance to ensure its continued safety and functionality in the face of changing climate patterns.

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.
