Hackney Millpond Dam dam
Hackney Millpond Dam
Hackney Millpond Dam, located in Siler City, North Carolina, was completed in 1831 and stands as a historic masonry structure along the Rocky River. With a hydraulic height of 9 feet and a structural height of 12 feet, this dam serves primarily for recreation purposes, offering a tranquil setting for water resource and climate enthusiasts to enjoy. The dam has a storage capacity of 85 acre-feet, providing a serene environment for outdoor activities.
Despite its age, the Hackney Millpond Dam has a low hazard potential and has not been rated for its condition. While the last inspection took place in 1976, the dam continues to stand as a testament to the engineering expertise of its time. With a maximum discharge of 185 cubic feet per second, this dam plays a crucial role in managing water flow along the Rocky River. Although it is not regulated by the state, the dam's historical significance and recreational value make it a beloved landmark in the Chatham County area.
As water resource and climate enthusiasts explore the beauty of the Hackney Millpond Dam, its tranquil waters and scenic surroundings provide a captivating backdrop for outdoor adventures. With its rich history dating back to the 19th century, this masonry dam stands as a testament to the engineering ingenuity of the past. As visitors bask in the serenity of the pond created by the dam, they can appreciate its role in providing a peaceful retreat for nature lovers and outdoor enthusiasts alike.

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 Hackney Millpond Dam
Where does the data for Hackney Millpond 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.
