Hot Springs Equalization Basin dam
Hot Springs Equalization Basin
Hot Springs Equalization Basin in Garland County, Arkansas, serves as a critical water resource management structure for the area. Completed in 1994, this earth dam stands at a height of 31 feet and has a storage capacity of 232 acre-feet. With a normal storage capacity of 175 acre-feet and a surface area of 14 acres, the basin plays a vital role in maintaining water levels and managing discharge in the area's Lake Catherine tributary.
Owned and regulated by the local government, the Hot Springs Equalization Basin is inspected, permitted, and enforced by the Arkansas Natural Resources Commission (ANRC). Situated within the Little Rock District, the basin's low hazard potential and "Not Rated" condition assessment reflect its stable and well-maintained status. Despite its primary purpose being classified as "Other," the basin's importance in water resource management is evident through its design specifications and operational capabilities.
With a minimal risk assessment and emergency action plan in place, the Hot Springs Equalization Basin stands as a crucial component in the region's water resource infrastructure. As climate change continues to impact water availability and quality, structures like the basin play a vital role in ensuring sustainable water management practices in Arkansas. Enthusiasts of water resources and climate resilience will find the Hot Springs Equalization Basin to be a fascinating example of local government-led water infrastructure that serves both practical and environmental 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.
Plan around the weather

About Hot Springs Equalization Basin
Where does the data for Hot Springs Equalization Basin 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.
