Van Martin Dam dam
Van Martin Dam
Van Martin Dam, also known as Martin's Dam, is a privately owned structure located in Mayodan, North Carolina, along the Tr-Mayo River. Built in 1980 by the USDA NRCS, this earth dam stands at a height of 27 feet and stretches 586 feet in length, with a maximum storage capacity of 24 acre-feet primarily used for irrigation purposes. The dam has a low hazard potential and a moderate risk assessment rating.
The dam's spillway, with a width of 37 feet, is uncontrolled, and it has an uncontrolled outlet gate system. The surrounding area has a drainage area of 0.04 square miles and a surface area of 2 acres. Despite limited information on its current condition assessment, the dam is subject to inspections every 5 years to ensure its structural integrity and safety. While there are no associated structures with the dam, its primary purpose is for irrigation and secondary purposes include fish and wildlife pond support.
Van Martin Dam plays a crucial role in water resource management and irrigation in the region, contributing to the conservation of water for agricultural activities. With its location within Rockingham County, North Carolina, the dam serves as a vital infrastructure for local water supply and wildlife habitat preservation along the Tr-Mayo River. As a privately owned structure, the dam reflects the collaboration between private ownership and governmental agencies like the USDA NRCS in ensuring sustainable water resource utilization for the community.

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 Van Martin Dam
Where does the data for Van Martin 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.
