Mckinney Lake Dam dam
Mckinney Lake Dam
Mckinney Lake Dam, located in Ledbetter, North Carolina, is a federal-owned structure that plays a crucial role in providing water supply to the surrounding area. Built in 1939, this earth dam stands at a height of 23 feet and has a storage capacity of 1848 acre-feet. The dam, designed by Schnabel Engineering Assoc., Inc & URS Corporation, spans 440 feet in length and is primarily used for water supply purposes.
State-regulated by the NCDEQ Dam Safety Program, Mckinney Lake Dam has undergone modifications in 2001 to enhance its foundation, hydraulic, and structural integrity. With a significant hazard potential but a satisfactory condition assessment as of 2009, the dam is subject to regular inspections every three years to ensure its safety and functionality. In the event of emergencies, the dam is equipped with controlled outlet gates for proper water release.
With its location on Hitchcock Creek and association with the Wilmington District of the US Army Corps of Engineers, Mckinney Lake Dam stands as a vital infrastructure for water resource management in Richmond County, North Carolina. Water resource and climate enthusiasts can appreciate the dam's historical significance, engineering design, and ongoing efforts to maintain its safety and operational effectiveness in providing essential water supply to the region.
Dam data reference
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.
Plan around the weather

About Mckinney Lake Dam
Where does the data for Mckinney 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 Significant 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.
