1516 Glenn Valley Dam dam
1516 Glenn Valley Dam
The 1516 Glenn Valley Dam is a privately owned structure located in Matthews, North Carolina, within Mecklenburg County. 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
- 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.
- 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.
- 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.
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, environmental 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.

About 1516 Glenn Valley Dam
Where does the data for 1516 Glenn Valley Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
