Summary

Dalton Dam, is a private-owned recreational structure designed by Robert Lewis. Completed in 1989, this earth dam stands at a height of 46 feet and stretches 900 feet in length. With a normal storage capacity of 650 acre-feet and a maximum storage of 665 acre-feet, Dalton Dam is a vital resource for the local community.

Sitting on the Tributary of South Moreau Creek, this dam is regulated and inspected by the Dam and Reservoir Safety Program in Missouri. Despite its high hazard potential, the dam is currently in satisfactory condition and has a moderate risk assessment rating. With a spillway width of 120 feet and a maximum discharge capacity of 2066 cubic feet per second, Dalton Dam ensures the safety and security of the surrounding areas in the event of emergencies.

Enthusiasts of water resources and climate change will find Dalton Dam a fascinating structure that not only provides recreational opportunities but also serves as a crucial asset for flood control and water storage in Cole County, Missouri. With its strategic location and well-maintained condition, this dam stands as a testament to effective dam management and regulatory oversight in the region.

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. 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

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, 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.
