About this dam

Nezzie W Nisbet Dam

Nestled in the picturesque landscape of Lancaster, South Carolina, the Nezzie W Nisbet Dam stands as a testament to human ingenuity and the symbiotic relationship between water resources and climate. Completed in 1950, this private-owned Earth dam serves primarily for recreational purposes, offering a tranquil escape for water enthusiasts and nature lovers alike. With a height of 35 feet and a length of 220 feet, the dam boasts a storage capacity of 56 acre-feet, providing a serene surface area of 7 acres for recreational activities.

Despite its low hazard potential, the Nezzie W Nisbet Dam is in poor condition as of the last inspection conducted in September 2017. However, its risk management measures are deemed moderate, indicating a proactive approach to ensuring the safety and integrity of the structure. With state regulation, inspection, and enforcement in place, the dam continues to be a beloved recreational spot for locals and visitors, albeit with room for improvement in its maintenance and upkeep. As climate change continues to impact water resources, the importance of sustainable management and maintenance of dams like Nezzie W Nisbet becomes increasingly crucial.

As water resource and climate enthusiasts continue to appreciate the beauty and functionality of the Nezzie W Nisbet Dam, it serves as a reminder of the delicate balance between human intervention and natural ecosystems. With its tranquil waters and scenic surroundings, the dam stands as a beacon of recreational opportunity while also highlighting the need for ongoing monitoring and maintenance to ensure its long-term sustainability. In the face of evolving climate patterns and regulatory challenges, the Nezzie W Nisbet Dam remains a valuable asset for the community, offering both respite and responsibility in the stewardship of our water resources.

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 Nezzie W Nisbet Dam

Where does the data for Nezzie W Nisbet 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.
