Summary
This private earth dam stands at a height of 25 feet and has a storage capacity of 107 acre-feet. While the dam is classified as low hazard potential, it serves as a valuable resource for the surrounding community by offering recreational opportunities and contributing to the local ecosystem.
Managed by the Kansas City District of the US Army Corps of Engineers, Watters Lake Dam plays a crucial role in maintaining water levels for the TR to Little Calvey Creek. Despite its age, the dam's condition assessment is currently listed as "Not Rated," emphasizing the need for regular inspections and maintenance to ensure its long-term stability and functionality. With a moderate risk assessment rating and no emergency action plan in place, there is a growing need for proactive risk management measures to mitigate potential hazards and protect downstream areas in the event of a dam failure.
As water resource and climate enthusiasts continue to monitor the impact of dams on local ecosystems and communities, Watters Lake Dam stands as a testament to the importance of responsible dam management and maintenance. With its diverse range of purposes and relatively low hazard potential, this private earth dam serves as a valuable asset for both water conservation and recreational activities in the Pacific, Missouri area. Ongoing efforts to assess and address the dam's structural integrity will be crucial in ensuring the long-term sustainability of this essential water resource.

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.
