Lake Windsor Dam dam
Lake Windsor Dam
Lake Windsor Dam, located in Bella Vista Village, Arkansas, stands as a vital structure regulating the flow of Tanyard Creek. Built in 1974, this private Earth-type dam serves primarily for recreational purposes, providing a serene backdrop for water enthusiasts and nature lovers alike. With a height of 85 feet and a storage capacity of 9,400 acre-feet, the dam ensures a steady water supply for various recreational activities while also managing flood risks in the area.
The dam's significant hazard potential underscores the importance of its regular inspections and maintenance, although its current condition remains unrated. With a drainage area of 11.3 square miles and a maximum discharge capacity of 38,000 cubic feet per second, the Lake Windsor Dam plays a crucial role in water resource management in Benton County, Arkansas. Its location within the Tulsa District of the US Army Corps of Engineers further highlights its strategic importance in the region.
Despite its private ownership, the Lake Windsor Dam falls under state regulation and oversight by the Arkansas Natural Resources Commission (ANRC). With a surface area of 220 acres and a structural height of 95 feet, this dam not only enhances the scenic beauty of the area but also serves as a key component in ensuring water security and environmental sustainability in the region. For water resource and climate enthusiasts, Lake Windsor Dam stands as a testament to the harmonious coexistence of human recreation and natural resource management.

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 Lake Windsor Dam
Where does the data for Lake Windsor 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.
