Hoffner Lake Dam dam
Hoffner Lake Dam
Hoffner Lake Dam, located in Davie, North Carolina, serves as a vital structure for irrigation purposes along the Reedy Creek. Owned privately, the dam is regulated by the North Carolina Department of Environmental Quality's Dam Safety Program, ensuring state jurisdiction, permitting, inspection, and enforcement are in place. With a hydraulic height of 16 feet and a structural height of 20 feet, the dam holds a normal storage capacity of 38.4 acre-feet and a total storage of 48 acre-feet, making it crucial for water resource management in the region.
Despite its importance, Hoffner Lake Dam poses a high hazard potential and has been assessed to be in poor condition as of February 2021. The dam stretches 385 feet in length and covers a surface area of 6 acres, impacting a drainage area of 141 square miles. With a last inspection date in February 2021 and an inspection frequency of every 2 years, the dam's maintenance and safety measures are closely monitored. Although no spillway type or outlet gates are specified, the dam is designed as an earth structure, emphasizing the need for continued assessment and risk management protocols to safeguard the surrounding communities and environment.
As a significant irrigation resource in the area, Hoffner Lake Dam plays a crucial role in water distribution and management. With its high hazard potential and poor condition, ongoing maintenance and oversight are essential to ensure the safety and integrity of the structure. The dam's location in Davie, North Carolina, calls for active engagement from local authorities, stakeholders, and the community to address any potential risks and implement necessary risk management strategies.

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 Hoffner Lake Dam
Where does the data for Hoffner 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.
