Hidden Lake Dam dam
Hidden Lake Dam
Hidden Lake Dam, also known as Thomas Lake Dam and Cedar Lake Dam, is a private dam located in Rocky Mount, North Carolina. Built in 1974, the dam serves primarily for irrigation purposes along Brandy Creek. Standing at a structural height of 25 feet with a hydraulic height of 18 feet, the dam has a storage capacity of 863 acre-feet, with a normal storage capacity of 720 acre-feet.
Owned privately, the Hidden Lake Dam is regulated by the North Carolina Department of Environmental Quality's Dam Safety Program. With a low hazard potential and a satisfactory condition assessment as of November 2018, the dam is inspected every five years to ensure its safety and compliance with state regulations. Despite its age, the dam continues to play a crucial role in managing water resources in the region and supporting agricultural activities through irrigation.
Situated in Franklin County, the Hidden Lake Dam serves as a vital infrastructure for water management in the area. With its strategic location and purpose, the dam contributes to the sustainable use of water resources along Brandy Creek, showcasing the importance of private ownership in maintaining and operating critical water infrastructure for the community's benefit amid changing climate conditions.

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 Hidden Lake Dam
Where does the data for Hidden 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 Low 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.
