About this dam

Stony Mountain Lake Dam #1

Stony Mountain Lake Dam #1, located in Cheraw Sc, North Carolina, is a private earth dam designed by the USDA NRCS for purposes such as fire protection, stock, and small fish ponds. With a hydraulic height of 13 feet and a structural height of 18 feet, this dam serves as a crucial water resource for the area. The dam has a low hazard potential and is currently not rated in terms of condition assessment. Despite being uncontrolled, the spillway type is uncontrolled as well, ensuring the safety and stability of the dam.

The dam has a storage capacity of 56 acre-feet and covers an 8-acre surface area. It is inspected regularly by state agencies, with the last assessment conducted in October 2017. The risk assessment for Stony Mountain Lake Dam #1 is moderate, indicating a need for ongoing monitoring and management measures to ensure its continued safety and functionality. Overall, this dam plays a vital role in providing water resources for fire protection, livestock, and recreational purposes in the region.

Despite its private ownership, Stony Mountain Lake Dam #1 is a significant structure within the local water resource infrastructure. With its primary purpose being fire protection and stock supply, the dam serves as a key asset for the community. As climate change continues to impact water resources, the importance of maintaining and monitoring dams like Stony Mountain Lake Dam #1 becomes increasingly crucial to ensure the sustainability and resilience of the local water supply in the face of changing environmental conditions.

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 Stony Mountain Lake Dam #1

Where does the data for Stony Mountain Lake Dam #1 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.
