Summary
Constructed in 1960, this dam stands at a height of 20 feet and has a storage capacity of 54 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," John Foster serves a primary purpose that is classified as "Other," indicating its multifaceted role in water resource management.
Managed by the Little Rock District of the US Army Corps of Engineers, John Foster's structural design features a Buttress core type with an unlisted/unknown foundation. The dam's normal storage capacity is 27 acre-feet, covering a surface area of 5 acres and draining an area of 40 square miles. While the dam has not been inspected in recent years and lacks certain emergency preparedness measures, its overall risk assessment remains undefined, leaving room for further evaluation and potential enhancements to its safety protocols.
Despite its lack of recent oversight and assessment updates, John Foster's presence along the TR Middle Indian Creek highlights the importance of monitoring and maintaining the integrity of dams in rural areas like Howell County, Missouri. As climate change continues to impact water resources and weather patterns, ensuring the reliability and safety of dams like John Foster becomes increasingly crucial for sustainable water management and community resilience.

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.
