Summary

Built in 1960, this dam stands at a height of 30 feet and has a storage capacity of 835 acre-feet. The dam is situated on Lost Creek, with a drainage area of 4800 acres and a surface area of 52 acres.

Despite its high hazard potential, the condition of Hart Development Lake Dam Sect 10 is currently not rated. The dam has not been inspected recently, and there is no emergency action plan in place. With no state regulation, permitting, inspection, or enforcement, the dam's risk management measures and emergency preparedness are unclear. This information may be concerning for water resource and climate enthusiasts interested in the safety and management of dams in Missouri.

Given the lack of recent inspections and emergency preparedness for Hart Development Lake Dam Sect 10, there is a need for further evaluation and potential improvements to ensure the safety of the surrounding community and environment. As a privately owned dam with a focus on recreation, it is important to address any potential risks and implement appropriate risk management measures. Water resource and climate enthusiasts may want to advocate for increased oversight and safety measures for this dam to prevent any potential hazards in the future.

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.
