Ozark Water Supply Lake Dam dam
Ozark Water Supply Lake Dam
Located in Franklin, Arkansas, the Ozark Water Supply Lake Dam is a critical piece of infrastructure for the local government of Felker Town. Completed in 1971, this earth dam stands at a height of 85 feet and has a hydraulic height of 90 feet, serving as a vital source of water supply for the region. With a normal storage capacity of 12,000 acre-feet and a drainage area of 18.5 square miles, the dam plays a key role in managing water resources in the area.
Managed by the Arkansas Natural Resources Commission (ANRC), the Ozark Water Supply Lake Dam is classified as a significant hazard potential structure with a condition assessment that has not been rated. The dam's last inspection was conducted in July 2014, highlighting the need for ongoing monitoring and maintenance to ensure its structural integrity and safety. With a maximum discharge capacity of 16,950 cubic feet per second, the dam plays a crucial role in mitigating flood risks and providing a reliable water source for the community.
Despite its importance, the Ozark Water Supply Lake Dam lacks certain emergency preparedness measures, such as an Emergency Action Plan (EAP) and inundation maps. As climate change continues to impact water resources and weather patterns, it is essential for local authorities to prioritize the safety and resilience of critical infrastructure like the Ozark Water Supply Lake Dam. With proper risk assessment and management measures in place, the dam can continue to fulfill its primary purpose of supplying clean water to the residents of Felker Town for years to come.
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 Ozark Water Supply Lake Dam
Where does the data for Ozark Water Supply Lake 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 Significant 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.
