About this dam

Forest Lake Dam

Forest Lake Dam, located in York, South Carolina, stands as a significant earth dam completed in 1955 for recreational purposes. With a height of 23 feet and a length of 330 feet, this dam provides a storage capacity of 59 acre-feet and covers an area of 11 acres. Situated on the TR-STEELE CREEK river, the dam is privately owned and regulated by the South Carolina Department of Health and Environmental Control (DHEC). Despite its poor condition assessment and high hazard potential, the dam has been inspected regularly, with the last assessment conducted in December 2019.

The Forest Lake Dam poses a potential risk due to its poor condition, prompting a high hazard potential designation. With a history of modifications and regular inspections, its current state and maintenance practices are crucial in ensuring the safety of the surrounding community and the preservation of the dam's intended recreational purpose. The dam's location within the Wilmington District and its ownership by a private entity further emphasize the need for continued monitoring and adherence to regulatory standards to mitigate any potential risks associated with its operation.

As a vital part of the local water resource infrastructure, Forest Lake Dam serves as a recreational reservoir with a primary purpose to provide leisure activities for the community. Its structural design, including stone core materials and soil foundations, highlights the importance of maintaining its integrity to sustain its maximum storage capacity and normal operations. With ongoing enforcement, inspection, and permitting by state agencies, the dam remains a focal point for water resource and climate enthusiasts to monitor and ensure its long-term sustainability and safety.

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 Forest Lake Dam

Where does the data for Forest Lake 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 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.
