Summary
Built in 1972, this earth dam stands at a height of 24 feet and spans 600 feet in length, with a storage capacity of 82 acre-feet. Its purpose is to stabilize the surrounding area and prevent erosion, serving as a vital component in managing water resources in the region.
Despite being privately owned, Johnson Land Development Lake Dam falls under the jurisdiction of the state of Missouri and is not regulated or inspected by state agencies. With a low hazard potential and a moderate risk assessment rating of 3, the dam is considered to be in good condition, although its emergency action plan and risk management measures are currently not rated or updated. The dam features an uncontrolled spillway, outlet gates, and a stone core foundation, further showcasing its importance in water resource management and climate resilience efforts in the area.
In the event of an emergency, it is crucial for stakeholders to ensure that proper risk assessment and management measures are in place for Johnson Land Development Lake Dam. With its strategic location and significant role in grade stabilization, this earth dam serves as a key infrastructure for water resource enthusiasts and climate advocates to monitor and support in efforts to safeguard against potential risks and ensure the sustainable management of water resources in Daviess County, Missouri.

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.
