Cooper Lake Dam dam
Cooper Lake Dam
Cooper Lake Dam, located in Cabot, Arkansas, is a private-owned structure designed by the USDA NRCS in 1950 for the primary purpose of recreation. This earth dam stands at a height of 22 feet and spans 200 feet in length, with a storage capacity of 100 acre-feet. Situated on Bayou Two Prairie-TR, the dam is managed by the Vicksburg District of the US Army Corps of Engineers and is deemed to have a significant hazard potential.
Despite not being state-regulated, Cooper Lake Dam poses a moderate risk, with its condition assessed as not rated. The dam's spillway type is uncontrolled, and it currently does not have any outlet gates or associated structures. While the emergency action plan has not been prepared or updated, the dam meets guidelines for risk assessment, with measures in place to manage potential risks.
Water resource and climate enthusiasts may find Cooper Lake Dam intriguing for its recreational purpose and design by the USDA NRCS. With its significant hazard potential and moderate risk assessment, the dam serves as a critical structure in the Lonoke County region of Arkansas. As a private-owned facility, its management and maintenance are of utmost importance to ensure the safety and security of the surrounding communities and water resources.
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 Cooper Lake Dam
Where does the data for Cooper 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.
