About this dam

Tull Millpond Dam

Tull Millpond Dam, located in Deep Run, North Carolina, is a private structure built in 1875 primarily for recreational purposes. The dam, constructed of earth, spans 1000 feet across Southwest Creek and stands at a structural height of 8 feet with a hydraulic height of 6 feet. With a normal storage capacity of 432 acre-feet and a maximum storage of 518 acre-feet, the dam covers a surface area of 160 acres and serves a drainage area of 4670 acres.

Despite its age, Tull Millpond Dam has been consistently regulated, inspected, and enforced by the North Carolina Dam Safety Program to ensure its safety and compliance with state regulations. The dam's condition was last assessed as satisfactory in December 2020, with a high hazard potential due to its location and capacity. With an inspection frequency of 2 years, the dam is monitored closely to mitigate any risks and ensure its continued functionality for recreation and water resource management for the community.

As a vital structure in the region, Tull Millpond Dam plays a crucial role in providing recreational opportunities and water storage for the surrounding area. With its rich history dating back over a century, the dam stands as a testament to the engineering ingenuity of the past and the ongoing commitment to maintaining and safeguarding water resources in the face of changing climates and environmental challenges.

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.

FAQ

About Tull Millpond Dam

Where does the data for Tull 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 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.
