International Speedway dam
International Speedway
International Speedway in Kansas is a state-owned dam designed by HNTB Corporation for flood risk reduction on the Little Turkey Creek-TR. This earth dam stands at 35 feet tall and spans 282 feet in length, with a storage capacity of 448.5 acre-feet. Despite its fair condition assessment and high hazard potential, the dam is regularly inspected by the Kansas Department of Agriculture to ensure its safety and compliance with state regulations.
Located in Wyandotte County, Kansas, International Speedway plays a crucial role in managing water resources and protecting the surrounding area from potential flooding events. With a maximum discharge capacity of 924.5 cubic feet per second and a spillway width of 135 feet, the dam serves as a vital infrastructure for flood control. While the dam is currently deemed to have a moderate risk level, ongoing risk management measures and regular inspections help mitigate potential hazards and ensure the safety of the community.
Managed by the Kansas state government, International Speedway serves as a key component of the flood risk reduction strategy in the region. As part of its purpose, the dam helps regulate water flow and prevent potential flooding in the area. With a focus on maintaining safety and compliance, the dam is subject to regular inspections and oversight by state regulatory agencies to uphold its function and protect the surrounding environment. For water resource and climate enthusiasts, International Speedway stands as a critical infrastructure for managing water resources and mitigating flood risks in Kansas.

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 International Speedway
Where does the data for International Speedway 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 High 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.
