About this dam

Dennon Jones Lower Dam

Dennon Jones Lower Dam, also known as Dorthy Jones Dam 2, is a private-owned structure located in Laurens, South Carolina. Built in 1959, this earth-type dam stands at a height of 18 feet and spans a length of 360 feet, creating a storage capacity of 54 acre-feet with a primary purpose of recreation. Situated on TR-BEAVERDAM CREEK, this dam offers a serene setting for water resource and climate enthusiasts to explore the surrounding area and enjoy various recreational activities.

Despite its low hazard potential, the dam is in poor condition as of the last assessment in 2017. The South Carolina Department of Health and Environmental Control (DHEC) oversees the state regulation, permitting, inspection, and enforcement of this structure to ensure public safety and environmental protection. With a limited inspection frequency of every 5 years, it is essential for stakeholders to prioritize maintenance and potentially consider rehabilitation measures to address the dam's deteriorating condition.

As an integral part of the local water management infrastructure, Dennon Jones Lower Dam serves as a valuable resource for the community. With proper care and attention, this dam can continue to provide recreational opportunities while safeguarding the surrounding area against potential risks and hazards. Engaging with state regulators and implementing necessary maintenance actions will be crucial in preserving this structure for future generations of water resource and climate enthusiasts to enjoy.

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 Dennon Jones Lower Dam

Where does the data for Dennon Jones Lower 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.
