Chavis Dam dam
Chavis Dam
Chavis Dam, located in Wake County, North Carolina, is a privately owned structure with a primary purpose that goes beyond water resource management. The dam, classified as an Earth type, stands at a hydraulic height of 8 feet and a structural height of 10 feet, with a length of 145 feet. Despite its relatively small size, Chavis Dam holds a maximum storage capacity of 4 acre-feet and covers a surface area of 0.8 acres.
The dam's high hazard potential is a significant concern, although its condition assessment remains unrated as of the last inspection in November 2018. The emergency action plan status, risk assessment, and inundation maps for Chavis Dam are not readily available, raising questions about its preparedness in case of a catastrophic event. While the dam is not under state jurisdiction, it is subject to periodic inspections, suggesting ongoing monitoring of its safety and integrity.
For water resource and climate enthusiasts, Chavis Dam presents an intriguing case study of a modest-sized structure with potential risks and unknown emergency preparedness measures. Its location in North Carolina, a state prone to extreme weather events, adds to the importance of understanding the dam's condition and management practices. As discussions around infrastructure resilience and climate adaptation continue, monitoring the safety and functionality of dams like Chavis Dam is crucial for ensuring the protection of communities and ecosystems downstream.

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 Chavis Dam
Where does the data for Chavis 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.
