Summary
Standing at a structural height of 27 feet and a hydraulic height of 25 feet, the dam has a storage capacity of 100 acre-feet and a normal storage level of 55 acre-feet. Despite its low hazard potential, the dam poses a moderate risk, prompting the need for risk management measures to ensure its safety and integrity.
With a spillway width of 30 feet and a maximum discharge of 92 cubic feet per second, Williams Lake Dam 2 plays a critical role in flood protection in the area. The dam also serves multiple purposes including fire protection, irrigation, and recreation, making it a valuable resource for the local community. While the dam has not been rated for its condition assessment, it is essential to regularly monitor and maintain the structure to prevent any potential risks or hazards.
As a key infrastructure in the Kansas City District, Williams Lake Dam 2 is closely monitored by the local authorities to ensure its proper functioning and safety. With its strategic location and multiple benefits for the surrounding area, the dam continues to be an important asset for water resource management and climate resilience efforts in Henry County, Missouri.

Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
