Hollow Creek Watershed Dam 1 dam
Hollow Creek Watershed Dam 1
Hollow Creek Watershed Dam 1, located in Lexington, South Carolina, was completed in 1986 by the USDA NRCS and serves the primary purpose of flood risk reduction. This earth dam stands at a height of 44 feet, with a storage capacity of 1450 acre-feet and a surface area of 57 acres. It is regulated by the South Carolina DHEC and is subject to state permitting, inspection, and enforcement to ensure its structural integrity and compliance with safety standards.
The dam's low hazard potential and fair condition assessment make it a reliable structure for managing water resources in the area. With a spillway type of uncontrolled and unlisted/unknown foundation, Hollow Creek Watershed Dam 1 plays a crucial role in mitigating flood risks and providing opportunities for recreational activities. Its moderate risk assessment rating emphasizes the importance of ongoing monitoring and risk management measures to safeguard the surrounding community and environment.
As part of the Savannah District under the USACE, this dam contributes to water resource management efforts in the region. With its strategic location on Hollow Creek and the support of local government ownership, Hollow Creek Watershed Dam 1 stands as a testament to collaborative efforts in maintaining critical infrastructure for flood control and recreational purposes.
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 Hollow Creek Watershed Dam 1
Where does the data for Hollow Creek Watershed 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.
