About this dam

Merritts Pond

Merritts Pond in Pickens, South Carolina, is a privately-owned recreational reservoir designed by the USDA NRCS and regulated by the SC DHEC. Built in 1972, this earth dam stands at a height of 28 feet and spans 475 feet in length, with a storage capacity of 68 acre-feet. The pond covers a surface area of 5 acres and is primarily utilized for recreational purposes, offering a serene setting for outdoor enthusiasts to enjoy.

Despite its fair condition assessment, Merritts Pond poses a high hazard potential due to its uncontrolled spillway and outlet gates. With a moderate risk assessment rating, the dam is inspected biennially to ensure its structural integrity and safety measures are up to standard. The surrounding area is at risk of inundation in the event of a breach, emphasizing the importance of ongoing risk management and emergency preparedness protocols for this water resource.

Situated along the TR-THREE AND TWENTY CREEK, Merritts Pond serves as a vital water source in the region and contributes to the overall ecosystem health. As climate change continues to impact water resources, the maintenance and conservation efforts for Merritts Pond are crucial in ensuring its continued function and safety for both recreational and environmental purposes.

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 Merritts Pond

Where does the data for Merritts Pond 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 High 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.
