City Lake Dam dam
City Lake Dam
City Lake Dam, located in Harrisonville, Missouri, was completed in 1934 and serves as a critical infrastructure for water supply purposes. This earth dam, with a height of 22 feet, has a storage capacity of 247 acre-feet and covers a drainage area of 461 acres. The dam, situated on Town Creek, has a surface area of 21 acres and a normal storage capacity of 107 acre-feet.
Despite being classified as having a high hazard potential, City Lake Dam has not been rated for its condition assessment. The last inspection of the dam was conducted in April 1979, with no subsequent inspections reported. The dam's emergency action plan status, risk assessment, and risk management measures are also unknown. With its critical role in water supply and the potential risks associated with its high hazard classification, monitoring and maintenance of City Lake Dam are crucial to ensure the safety and security of the surrounding community and environment.
As a key water resource structure owned by the local government, City Lake Dam on TOWN CREEK in Cass County, Missouri, falls under the jurisdiction of the Tulsa District of the U.S. Army Corps of Engineers. With no state regulation or permitting in place, the dam's operation, inspection, and enforcement are solely managed by the local government. In the absence of recent assessments and with limited information on emergency preparedness and risk mitigation measures, the future maintenance and monitoring of City Lake Dam are essential to safeguard its integrity and protect the community from potential hazards.

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 City Lake Dam
Where does the data for City 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 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.
