Summary
This earth dam with a structural height of 20 feet helps create a reservoir with a normal storage capacity of 60 acre-feet and a surface area of 9 acres. The dam's hazard potential is rated as low, and its condition assessment is marked as "Not Rated."
Despite being privately owned, Foster Lake Dam falls under the jurisdiction of the state of Missouri and is not regulated or inspected by any state agency. The dam, situated on the TR-Colburn BR Blackwater River, does not have a spillway and is not associated with any federal agency. While the dam's emergency action plan status and risk assessment remain unknown, it serves as a vital resource for water enthusiasts and climate advocates in the area.
With a maximum storage capacity of 96 acre-feet and a drainage area of 40 acres, Foster Lake Dam provides a serene recreational spot for visitors. While lacking certain regulatory measures and inspection frequencies, the dam's presence contributes to the local ecosystem and offers a tranquil escape for those interested in water resources and climate monitoring in Johnson County, Missouri.

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.
