Summary
With a height of 45 feet and a storage capacity of 39 acre-feet, this dam serves the purpose of flood control and water storage for the surrounding area. The dam has a significant hazard potential but is currently in satisfactory condition, as assessed in December 2014.
Managed by the Dam and Reservoir Safety Program in Missouri, Stonegate Dam undergoes regular inspections, with the last one conducted in February 2017. The dam is regulated by the state and meets all permitting and enforcement requirements. Situated in the Kansas City District and with a maximum discharge capacity of 100 cubic feet per second, Stonegate Dam plays a crucial role in managing water resources and ensuring water security in the region.
Stonegate Dam is an essential structure in the water management infrastructure of Missouri, providing flood protection and water storage capabilities for the local community. With its efficient design and regulatory oversight, the dam continues to be a reliable asset for water resource and climate enthusiasts in the region. Its location in Turners Station, Missouri, and the dedication to ongoing maintenance and inspection ensure the safety and effectiveness of Stonegate Dam for years to come.

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.
