Patocca Lower Lake Dam dam
Patocca Lower Lake Dam
Located in Palmyra, Arkansas, the Patocca Lower Lake Dam is a private-owned structure designed by the USDA NRCS with a primary purpose of recreation. Completed in 1970, this earth dam stands at a hydraulic height of 13 feet and a structural height of 15 feet, with a total length of 522 feet. The dam has a maximum storage capacity of 60 acre-feet and a normal storage of 31 acre-feet, serving as a vital resource for water supply and leisure activities in the area.
With a low hazard potential and a moderate risk assessment rating, the Patocca Lower Lake Dam plays a crucial role in managing water resources in Lincoln County. While it is not regulated by the state and lacks regular inspections, the dam remains an important structure for the community, offering recreational opportunities and serving as a key component in flood control and water management. Despite its age, the dam continues to provide essential services to the surrounding areas.
As water resource and climate enthusiasts explore the diverse landscapes of Arkansas, the Patocca Lower Lake Dam stands as a testament to the importance of sustainable water management and recreational infrastructure. With its serene surroundings and functional design, this dam serves as a reminder of the delicate balance between human needs and environmental stewardship, showcasing the harmonious relationship between water resources and community development in the region.

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 Patocca Lower Lake Dam
Where does the data for Patocca Lower 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 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.
