Summary
Williams Lake Dam No 1, also known as Williams Lake Dam, is a privately owned earthen dam located in Warsaw, Missouri. Built in 1977, the dam serves primarily for grade stabilization and irrigation purposes along TR-HONEY CREEK. Standing at a height of 22 feet and with a length of 600 feet, the dam has a storage capacity of 172 acre-feet and covers a surface area of 5.2 acres. Despite not being state regulated, the dam is considered to have a significant hazard potential due to its location and design.
The dam is situated within the Kansas City District and falls under the jurisdiction of Vicky Hartzler (R), the Congressional Representative for the area. Although not currently rated for its condition, the dam's risk assessment is moderate, with a risk level of 3 out of 5. With an uncontrolled spillway and no outlet gates, the dam has a maximum discharge capacity of 54 cubic feet per second. While the dam has not been inspected recently and lacks an Emergency Action Plan (EAP), it remains a crucial structure for water resource management in the region.
Water resource and climate enthusiasts will find B. Williams Lake Dam No 1 to be an intriguing example of private dam infrastructure in Missouri. Its unique design, purpose, and risk assessment provide insight into the complexities of managing water resources in the region. As a significant grade stabilization and irrigation structure, the dam plays a crucial role in supporting local agriculture and water supply needs. Additionally, its location along TR-HONEY CREEK highlights the interconnectedness of water systems and the importance of sustainable water management practices in the face of climate change challenges.

Dam Data Reference
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.
