Wyandotte County Lake Dam dam
Wyandotte County Lake Dam
Wyandotte County Lake Dam, also known as Marshall Creek Dam, is a local government-owned structure located in Kansas City, Kansas. Completed in 1941 by the Corps of Engineers, this earth dam stands at a height of 97.5 feet with a hydraulic height of 118 feet and a structural height of 139 feet. It spans a length of 1790 feet and has a normal storage capacity of 10,000 acre-feet. Situated on the Missouri River, the dam serves primarily for recreational purposes, offering a surface area of 375 acres for outdoor activities.
Despite being regulated by the Kansas Department of Agriculture and subject to state inspection and enforcement, the dam is classified as having a significant hazard potential with a fair condition assessment. The last inspection was conducted in March 2016, with a frequency of every 5 years. While the dam lacks certain safety features such as spillways and outlet gates, it remains a popular destination for water resource and climate enthusiasts seeking recreational opportunities in the Wyandotte County area. As one of the key structures in the region, the dam plays a vital role in managing water resources and providing a scenic backdrop for outdoor recreation.
With its historical significance and impressive design by the Corps of Engineers, Wyandotte County Lake Dam stands as a prominent landmark in the Kansas City District. Boasting a storage capacity of 14,700 acre-feet and a maximum discharge of 11,000 cubic feet per second, the dam continues to attract visitors seeking a tranquil environment amidst the natural beauty of the Missouri River. As efforts are made to ensure the safety and maintenance of this iconic structure, it remains a symbol of the harmonious coexistence between human development and environmental preservation 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 Wyandotte County Lake Dam
Where does the data for Wyandotte County 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.
