Johnson Millpond Dam #2 dam
Johnson Millpond Dam #2
Johnson Millpond Dam #2, located in Hamilton, North Carolina, is a privately owned earth dam built in 1950 for irrigation purposes on Occoneechee Creek. The dam stands at a hydraulic height of 8 feet and a structural height of 10 feet, with a length of 300 feet and a storage capacity of 96 acre-feet. Despite being non-regulated by the state, the dam has been inspected and deemed to have a low hazard potential, with a condition assessment of "Not Rated" as of its last inspection in 1976.
Owned and operated by a private entity, Johnson Millpond Dam #2 plays a crucial role in supporting irrigation and water supply in the region, highlighting the importance of private infrastructure in water resource management. The dam's association with the Norfolk District of the US Army Corps of Engineers underscores its significance in local water management efforts. While the dam's condition assessment is currently listed as "Not Rated," its low hazard potential suggests a need for periodic monitoring and potential updates to ensure continued safety and functionality for the surrounding community.
With its location in Northampton County, Johnson Millpond Dam #2 stands as a testament to the historical significance of water resource infrastructure in the region. As climate change continues to impact water availability and quality, maintaining and updating dams like Johnson Millpond Dam #2 will be key to ensuring sustainable water management practices for future generations. Moving forward, continued inspections and potential risk assessments will be essential to address any safety concerns and uphold the dam's role in supporting local water needs.

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 Johnson Millpond Dam #2
Where does the data for Johnson Millpond Dam #2 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.
