Catawba Reservoir No 2 dam
Catawba Reservoir No 2
Located in Lancaster, South Carolina, Catawba Reservoir No 2 is a state-regulated dam with a storage capacity of 3,940 acre-feet and a normal storage level of 3,450 acre-feet. The dam has a height of 100 feet and a surface area of 89.4 acres. Despite being classified as low hazard potential, the dam has not been rated for its condition and last underwent an emergency action plan review in May 2011.
Owned by a not-listed entity and managed by the South Carolina Department of Health and Environmental Control (SC DHEC), Catawba Reservoir No 2 serves as a critical water resource in the region. With state permitting, inspection, and enforcement in place, the dam ensures the safety and regulation of water flow in the area. While the dam's primary purpose and design details are not specified, its role in water storage and management is evident.
Catawba Reservoir No 2, part of the Wilmington District of the US Army Corps of Engineers, stands as a key infrastructure for water resource management in the region. Although lacking detailed information on its construction, operation, and modification history, the dam plays a crucial role in flood control, water storage, and environmental protection. Enthusiasts of water resources and climate will find interest in studying the impact and significance of Catawba Reservoir No 2 on the local ecosystem and water supply.

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 Catawba Reservoir No 2
Where does the data for Catawba Reservoir No 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.
