Summary

Completed in 1994, the dam stands at a structural height of 30 feet with a hydraulic height of 18 feet and a length of 220 feet. It has a storage capacity of 96 acre-feet and serves an area with a drainage area of 634 acres. Despite being classified as having low hazard potential, the dam is in fair condition and is regulated by the NCDEQ Dam Safety Program.

The dam is situated on the Hunting Creek-Os stream and is owned privately. It is subject to state jurisdiction, permitting, inspection, and enforcement by the North Carolina regulatory agencies. The last inspection in November 2019 found the dam to be in fair condition, with an inspection frequency of every 5 years. While the dam does not have an Emergency Action Plan (EAP) prepared or updated, it meets guidelines for risk assessment and management measures.

Toby Campbell Dam serves as a vital water resource for irrigation in the area, providing water for fire protection, stock, and small fish ponds. With its low hazard potential and fair condition, the dam continues to play a crucial role in managing water resources in Iredell County. Enthusiasts of water resources and climate will find interest in the structural and operational details of this privately owned dam in North Carolina.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
