Lake Corriher Dam dam
Lake Corriher Dam
Lake Corriher Dam, located in China Grove, North Carolina, stands as a vital structure for water supply in the region. Completed in 1953, this earth-type dam has a hydraulic height of 19 feet and a structural height of 23 feet, with a capacity to store 275 acre-feet of water. The dam, situated on Flat Rock Branch, serves as a significant source of water for the community, with a normal storage capacity of 120 acre-feet and a surface area of 29 acres.
Despite being classified as having a high hazard potential, Lake Corriher Dam is assessed to be in fair condition as of January 2019. The dam is regulated by the North Carolina Department of Environmental Quality's Dam Safety Program, ensuring that it undergoes regular inspections and enforcement measures to maintain its structural integrity. With a drainage area of 1279 square miles and a maximum discharge capacity of 1890 cubic feet per second, the dam plays a crucial role in managing water resources and mitigating flood risks in the area.
As a key component of the water supply infrastructure in Rowan County, Lake Corriher Dam not only provides essential water storage but also contributes to the overall resilience of the region in the face of changing climate patterns. Its strategic location and capacity to manage water flow make it a critical asset for water resource and climate enthusiasts interested in sustainable water management practices and infrastructure resilience in the face of environmental challenges.

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 Lake Corriher Dam
Where does the data for Lake Corriher 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.
