About this dam

Delta Lake Dam

Delta Lake Dam in Charlotte, North Carolina, is a privately owned structure that serves primarily for recreational purposes. The dam, classified as an Earth type, stands at a structural height of 20 feet with a hydraulic height of 18.7 feet. It impounds water from the Reedy Creek-Tr river and has a storage capacity of 68 acre-feet, with a normal storage level of 57 acre-feet. The dam has a surface area of 7.8 acres and a drainage area of 232 square miles.

Despite its satisfactory condition assessment as of December 2019, Delta Lake Dam poses a high hazard potential. Regular inspections are conducted every two years to ensure its safety and compliance with state regulations. The dam is under the jurisdiction and oversight of the North Carolina Department of Environmental Quality, Dam Safety Program, which is responsible for permitting, inspection, and enforcement. While the dam has not undergone any modifications in recent years, it is crucial for stakeholders and emergency responders to have updated emergency action plans in place to mitigate any potential risks associated with the dam.

In the event of an emergency, it is essential for the community and relevant authorities to have clear and effective communication channels and emergency response protocols. With its high hazard potential, Delta Lake Dam highlights the importance of proactive risk management and preparedness measures. As water resource and climate enthusiasts, it is crucial to stay informed about the safety and maintenance of such structures to ensure the protection of both the environment and the surrounding communities.

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 Delta Lake Dam

Where does the data for Delta Lake 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.
