Little Hell Hole Dam dam
Little Hell Hole Dam
Little Hell Hole Dam, located in Berkeley, South Carolina, is a Federal-owned structure managed by the USDA Forest Service. Built in 1934, this Earth-type dam stands at a height of 7 feet and spans a length of 600 feet along the Alligator Creek tributary. The dam primarily serves the purpose of a Fish and Wildlife Pond, with a storage capacity of 100 acre-feet. Despite its low hazard potential, the dam is classified with a very high risk assessment due to its age and lack of recent condition assessments.
This dam features a controlled spillway and outlet gates for managing water flow, with a history of inspections conducted by the Forest Service. Although the condition assessment is currently listed as "Not Rated," the risk management measures and emergency action plans for Little Hell Hole Dam remain unclear. With a drainage area of 4 square miles, the dam plays a crucial role in habitat conservation and water resource management in the region. Climate enthusiasts and water resource professionals can find valuable insights into the dam's design, function, and risk profile from the available data.
As water resources and climate change continue to impact dam safety and infrastructure resilience, the need for proactive risk management and maintenance of structures like Little Hell Hole Dam becomes increasingly important. The presence of a Federal agency overseeing the dam's operations and inspections provides a level of assurance, but further assessments and updated emergency action plans may be necessary to address the identified high-risk classification. By staying informed and engaged with the management of critical water resources such as this dam, enthusiasts can contribute to sustainable practices and safeguarding against potential hazards in the face of evolving environmental challenges.

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 Little Hell Hole Dam
Where does the data for Little Hell Hole 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.
