Summary
This earth dam stands at a hydraulic height of 11.3 feet and a structural height of 15.1 feet, with a length of 357 feet. With a normal storage capacity of 8 acre-feet and a maximum storage of 11 acre-feet, this dam serves a primary purpose that is classified as "Other." Despite being in fair condition according to the latest assessment in July 2020, the dam is considered to have a high hazard potential.
Managed by the North Carolina Department of Environmental Quality's Dam Safety Program, the 1516 Glenn Valley Dam is subject to state regulations, inspections, and enforcement. Its last inspection took place in July 2020, with a frequency of every two years. While no specific information is provided on the dam's construction year or design details, its location and characteristics indicate its importance in water resource management for the area. Given its high hazard potential, ensuring the safety and integrity of this dam is crucial for protecting downstream communities and the surrounding environment.
Water resource and climate enthusiasts interested in the infrastructure and management of dams will find the 1516 Glenn Valley Dam an intriguing subject of study. Its presence in a rapidly developing region like Mecklenburg County highlights the importance of effective dam regulation and maintenance to prevent potential hazards and ensure water security. Understanding the complexities of managing such critical structures in the face of changing climate patterns and increasing water demands is crucial for sustainable water resource management in the region.

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.
