About this dam

Mcguire Standby Nuclear Service Water Pond Dam

Mcguire Standby Nuclear Service Water Pond Dam, also known as Category I Emergency Cooling Water, is a crucial structure located in Huntersville, North Carolina. Owned by a public utility, the dam was designed by LAW ENGINEERING TESTING COMPANY in 1980. With a dam height of 68 feet and a length of 1260 feet, it serves as a standby resource for cooling water in case of emergencies at the nuclear facility.

Situated on the Catawba River, the dam has a storage capacity of 578 acre-feet and a surface area of 34.9 acres. Despite being categorized as low hazard potential, the dam is regularly inspected by the Nuclear Regulatory Commission, with the last assessment conducted in April 2017. The condition was found to be satisfactory, and the risk assessment is moderate with a score of 3.

Overall, Mcguire Standby Nuclear Service Water Pond Dam plays a vital role in ensuring the safety and security of the nuclear facility by providing a reliable source of emergency cooling water. Its strategic location and design make it an essential component of the infrastructure in Mecklenburg County, North Carolina, highlighting the importance of water resource management in the context of climate change and environmental sustainability.

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.

FAQ

About Mcguire Standby Nuclear Service Water Pond Dam

Where does the data for Mcguire Standby Nuclear Service Water Pond 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 Low 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.
