About this dam

Clearwater Lake Dam At Runaway Bay

Clearwater Lake Dam At Runaway Bay in Charlotte, North Carolina, is a privately owned structure regulated by the NC Department of Environmental Quality's Dam Safety Program. Completed in 1984, this earth dam stands at a hydraulic height of 11.6 feet and a structural height of 15.8 feet, with a total length of 400 feet. The dam serves primarily for recreational purposes and has a maximum storage capacity of 25.3 acre-feet, covering a surface area of 3.2 acres and draining an area of 480 acres along the Mcalpine Creek-Tr.

Despite being classified as a high hazard potential structure, the dam's condition is assessed as fair as of the last inspection in January 2020. The Emergency Action Plan (EAP) for the dam was last revised in May 2017, and the structure undergoes inspections every two years to ensure its safety and compliance with regulations. While the dam does not have a spillway or outlet gates, it plays a crucial role in providing recreational opportunities for the community while also managing water resources in the area. Enthusiasts of water resources and climate will find Clearwater Lake Dam a significant part of the local landscape, contributing to both recreation and water management efforts.

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 Clearwater Lake Dam At Runaway Bay

Where does the data for Clearwater Lake Dam At Runaway Bay 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.
