Summary
Owned by the local government and regulated by the NC Department of Environmental Quality, Dam Safety Program, this earth dam stands at a structural height of 14 feet and stretches over 1450 feet in length. With a high hazard potential, the dike has been assessed as satisfactory in condition, last inspected in January 2020 with a frequency of every 2 years.
Located in Mecklenburg County, the dike plays a vital role in protecting the surrounding area from potential flooding events. While the dam's primary purpose is flood risk reduction, it also serves as a critical infrastructure in the region. Although specific details such as completion year, storage capacity, and discharge rates are not provided, the dike's design and regulatory oversight ensure its effectiveness in safeguarding the community from water-related disasters.
Climate and water resource enthusiasts will appreciate the strategic importance of the Irwin Creek Flood Protection Dike in maintaining the safety and resilience of Charlotte's urban landscape. As part of the broader flood management system in the area, this structure highlights the collaborative efforts between local government and state agencies to mitigate flood risks and protect the community from the impacts of extreme weather events. The dam's satisfactory condition and regular inspections underscore its role as a reliable defense against potential inundation, making it a crucial asset in the region's climate adaptation and disaster preparedness strategies.

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.
