Summary
Completed in 1960, this earth dam stands at a height of 37 feet, with a length of 1270 feet and a storage capacity of 271 acre-feet. The dam's spillway, of uncontrolled type, has a width of 45 feet, and the maximum discharge capacity is 248 cubic feet per second. With a surface area of 22 acres and a drainage area of 76 square miles, Lake Wata Dam offers a picturesque setting for outdoor activities and serves as a vital water resource for the surrounding area.
Managed by the DAM AND RESERVOIR SAFETY PROG in Missouri, Lake Wata Dam has a low hazard potential and is deemed to be in satisfactory condition. The dam has undergone state inspection and enforcement, with a moderate risk assessment rating. The last inspection was conducted in March 2014, with a scheduled frequency of every 5 years. While there are no associated locks, outlet gates, or other structures, Lake Wata Dam remains a reliable and essential component of the local water management infrastructure.
For water resource and climate enthusiasts, Lake Wata Dam presents an intriguing example of how earth dams can effectively balance recreational and water supply purposes. With its scenic location and functional design, this dam serves as a critical asset for the community while ensuring the safety and sustainability of the surrounding environment. As efforts continue to maintain and manage this structure, Lake Wata Dam stands as a testament to the importance of responsible water resource management in the face of changing climate conditions.

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.
