Woodhaven Sub Dam 1 dam
Woodhaven Sub Dam 1
Woodhaven Sub Dam 1, located in McCormick, South Carolina, is a state-regulated dam with a height of 29 feet and a storage capacity of 35 acre-feet. The dam, which was last inspected in October 2017 and deemed to have a low hazard potential and fair condition, is owned by an entity not listed in the data. The dam is situated within the jurisdiction of the South Carolina Department of Health and Environmental Control (DHEC) and is subject to state permitting, inspection, and enforcement requirements.
Despite its relatively low hazard potential, Woodhaven Sub Dam 1 plays a crucial role in water resource management in the area, with a normal storage capacity of 18.4 acre-feet. While details about the dam's primary purpose, construction year, and associated structures are not provided in the data, its importance in maintaining water levels and mitigating flood risks in the region cannot be understated. With its location in Congressional District 03 of South Carolina and under the oversight of the Charleston District of the US Army Corps of Engineers, the dam serves as a vital infrastructure for ensuring water security and environmental resilience in the area.
Although specific information about the dam's design, construction, and modification history is not available, the data indicates that Woodhaven Sub Dam 1 has been well-maintained and meets state regulatory standards. With a regular inspection frequency of 5 years and a fair condition assessment as of October 2017, the dam continues to fulfill its role in water storage and management effectively. As a key component of the local water infrastructure, Woodhaven Sub Dam 1 underscores the importance of proactive monitoring and maintenance to ensure the safety and functionality of essential water resources in the region.

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.

About Woodhaven Sub Dam 1
Where does the data for Woodhaven Sub 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.
