Summary
30, located in Mcbaine, Missouri, is a private earth dam constructed in 1980 for the primary purpose of serving as a Fish and Wildlife Pond. With a dam height of 25 feet and a length of 450 feet, this structure has a normal storage capacity of 68 acre-feet and a maximum storage of 104 acre-feet. The dam sits on the TR-Perche Creek and is managed by the St. Louis District of the US Army Corps of Engineers.
Despite its low hazard potential and moderate risk assessment, Windmiller Lake Dam Sec. 30 has not been rated for its condition assessment. The dam features an uncontrolled spillway with a width of 22 feet and has no outlet gates. The surrounding area covers a surface area of 23 acres with a drainage area of 851 acres. While the dam has not been inspected recently, it is crucial for water resource and climate enthusiasts to monitor and assess its condition to ensure the safety and integrity of the structure for the protection of the local ecosystem and community.

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.
