Summary
Constructed in 1956, this private-owned Earth-type dam on the TR-WISCOY CREEK serves a crucial purpose in regulating water flow and providing a storage capacity of 110 acre-feet. With a length of 250 feet and a height of 13 feet, the dam boasts a spillway width of 40 feet, ensuring controlled discharge during peak flow events.
Despite being last inspected in 1977, Flint Marsh Dam maintains a low hazard potential and a moderate risk assessment rating of 3. Its condition remains unrated, but its design and functionality speak to the engineering expertise that went into its construction over six decades ago. The dam's presence not only safeguards the surrounding area from potential flooding but also highlights the importance of ongoing inspection, maintenance, and risk management measures to ensure its continued effectiveness in a changing climate.
As water resource and climate enthusiasts, the conservation and preservation of structures like Flint Marsh Dam are vital in maintaining the delicate balance of our ecosystems. With its state-regulated status and the potential for future risk assessment and management, this dam serves as a beacon of responsible infrastructure development in the face of climate challenges. Its history, design, and purpose underscore the critical role that dams play in water resource management and highlight the need for ongoing monitoring and adaptation to safeguard our communities and environment for generations to come.

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.
