Ladera Dam dam
Ladera Dam
Ladera Dam, located in Marvin, North Carolina, is a privately owned structure designed for flood risk reduction along the tributary to Six-Mile Creek. Managed by the NCDEQ Dam Safety Program, this earth dam stands at a hydraulic height of 7.4 feet and a structural height of 9.6 feet, with a total length of 250 feet. It has a normal storage capacity of 3 acre-feet and covers a surface area of 0.7 acres.
Despite being classified as having a high hazard potential, Ladera Dam is deemed to be in fair condition as of the last inspection in December 2019. With an inspection frequency of every two years, the dam is considered to meet guidelines for emergency action plans (EAPs), although the last revision of the EAP was in January 2014. While no risk assessment or management measures are currently reported, the dam continues to play a vital role in flood risk reduction for the surrounding area.
Water resource and climate enthusiasts will find Ladera Dam to be a fascinating example of private infrastructure contributing to public safety and environmental protection. As a key element in the flood risk reduction strategy for Union County, North Carolina, this earth dam highlights the importance of ongoing inspection and maintenance to ensure its continued effectiveness in mitigating potential hazards. The data provided offers a glimpse into the operational and regulatory aspects of this critical structure, serving as a reminder of the interconnectedness between water resources, climate resilience, and community safety.

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 Ladera Dam
Where does the data for Ladera 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.
