John De La Howe Dam dam
John De La Howe Dam
John De La Howe Dam, located in McCormick, South Carolina, is a state-owned earth dam built in 1990 for recreational purposes. Standing at a height of 28 feet and stretching 300 feet in length, the dam holds a maximum storage capacity of 45 acre-feet with a normal storage level of 27 acre-feet. Situated on the TR-Little River, this dam offers a serene setting for water resource and climate enthusiasts to enjoy various recreational activities.
Despite being classified as "Undetermined" in terms of hazard potential and "Not Rated" in condition assessment, John De La Howe Dam undergoes inspections every five years, with the last assessment conducted in September 2017. The dam's emergency action plan status, risk assessment, and management measures are currently not available, indicating a need for further evaluation and preparedness. With its picturesque location and potential for outdoor adventure, the dam serves as a focal point for those passionate about water resources and climate studies in the region.
Managed by the state of South Carolina and falling under the jurisdiction of the Charleston District of the US Army Corps of Engineers, John De La Howe Dam presents an intriguing opportunity for exploration and research in the field of water resource management and climate resilience. As enthusiasts delve into the specifics of this structure, its design, purpose, and operational aspects provide valuable insights into the intersection of human intervention and natural systems, making it a compelling subject for further study and appreciation among those interested in the dynamics of water resources and climate impacts.
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.

About John De La Howe Dam
Where does the data for John De La Howe 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 Undetermined 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.
