Willamette Industries Dam Dam
Willamette Industries Dam
The Willamette Industries Dam in Marlboro, South Carolina, stands as a testament to engineering prowess, completed in 1973 with a primary purpose of recreation. This earth dam, with a height of 14 feet and a length of 620 feet, holds a maximum storage capacity of 75 acre-feet, providing essential water resources for the surrounding area. Located on TR-PHILS CREEK, it serves as a vital recreational spot for water enthusiasts and nature lovers alike.
Despite its crucial role in water management and recreation, the Willamette Industries Dam poses a high hazard potential with a poor condition assessment as of October 2017. The dam's last inspection date was in October 2017, with a frequency of every two years. With its location in a high-risk area, the dam's emergency action plan status and risk management measures are crucial factors to consider for the safety and well-being of the local community.
As climate change continues to impact water resources and infrastructure, the Willamette Industries Dam serves as a reminder of the importance of regular maintenance, risk assessment, and emergency preparedness. With a private owner and state regulation in place, it is vital for stakeholders to work together to ensure the longevity and safety of this essential water resource for generations to come.

About Willamette Industries Dam
Where does the data for Willamette Industries 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 below 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.
Dam data reference
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.
