Harden Lake Dam:Old Dallas Dam dam
Harden Lake Dam:Old Dallas Dam
Harden Lake Dam, also known as Old Dallas Dam, is a private dam located in Hardins, North Carolina on the South Fork Catawba River. Built in 1901, this dam serves a primary purpose of hydroelectric power generation, with a structural height of 16 feet and a length of 235 feet. The dam has a normal storage capacity of 164 acre-feet and covers a surface area of 25.6 acres.
While the dam has a low hazard potential, its condition has not been rated as of the last inspection in October 2016. Despite not being state regulated or permitted, the dam is inspected by the state and meets inspection requirements. With a maximum discharge of 743 cubic feet per second, the Harden Lake Dam is an important structure for water resource management and climate enthusiasts interested in the hydroelectric capabilities of the South Fork Catawba River.
Although lacking in detailed risk assessment and emergency preparedness measures, Harden Lake Dam stands as a historical landmark in North Carolina's water infrastructure. With its contribution to hydroelectric power generation and minimal environmental impact, this dam serves as a testament to the early engineering feats of the region and continues to play a vital role in the local water resource management system.

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 Harden Lake Dam:Old Dallas Dam
Where does the data for Harden Lake Dam:Old Dallas 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.
