Summary

With a height of 14.7 feet and a storage capacity of 1350 acre-feet, this earth dam serves a crucial purpose in water resource management. The dam has a surface area of 202 acres and is regulated by the state of Michigan, with inspections and enforcement carried out regularly to ensure its safety and functionality.

Despite its high hazard potential, Tertiary Pond Dam has been assessed as satisfactory in condition, with a risk assessment rating of 2 (high). Emergency action plans are in place, although updates may be needed to meet current guidelines. The dam's last inspection in August 2019 revealed no significant issues, demonstrating its resilience and ability to withstand potential risks. Climate and water enthusiasts can appreciate the intricate design and importance of Tertiary Pond Dam in maintaining water resources in the region.

With its strategic location and significant storage capacity, Tertiary Pond Dam plays a vital role in water management in Midland, Michigan. As a key component in the local infrastructure, the dam not only provides storage capacity but also contributes to flood control and water regulation in the area. Its maintenance and regulatory oversight ensure its continued effectiveness in safeguarding the surrounding community and environment. Water resource and climate enthusiasts can find Tertiary Pond Dam to be a fascinating example of sustainable infrastructure management in action.

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.
