Summary
Sanitary District Water Storage Reservoir Dam, also known as the Cleveland County Offstream Reservoir Dam, is a vital structure in Lawndale, North Carolina, serving as a key water supply resource for the local community. Completed in 2010, this earth dam stands at a structural height of 53 feet and has a hydraulic height of 49 feet, with a storage capacity of 150 acre-feet. With a normal storage level of 123 acre-feet and a surface area of 7.1 acres, the dam plays a crucial role in managing water resources in the region.
Located on the UT to First Broad River, the dam is regulated by the NCDEQ Dam Safety Program and is subject to regular inspections to ensure its safe operation. With a high hazard potential and a fair condition assessment, the dam is equipped with emergency action plans to respond to any potential risks or incidents. The surrounding area has a drainage area of 42 square miles, with a maximum discharge capacity of 235 cubic feet per second, highlighting the importance of this reservoir in mitigating flood risks and providing a reliable water supply for the community.
Managed by the local government, the Cleveland Co. Sanitary District Water Storage Reservoir Dam represents a critical infrastructure for water resource management in Cleveland County. With its strategic location and significant storage capacity, this dam serves as a key asset in ensuring water security and resilience in the face of changing climate conditions.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
