Summary
The dam, with a height of 20 feet and a storage capacity of 107 acre-feet, is located on the TR-SOUTH FABIUS RIVER, within the Rock Island District. Despite being non-federally regulated, the dam is considered to have low hazard potential and is currently not rated in terms of condition assessment.
This earth dam, with a buttress core type, was completed in an unspecified year and has a normal storage capacity of 67 acre-feet. With a drainage area of 400 square miles, the dam serves as a crucial resource for the local area. Although it lacks certain details such as the last inspection date and condition assessment, the Wamsley Lake Dam plays a vital role in managing water resources and mitigating potential risks in the region.
With its strategic location and significance in water management, the Wamsley Lake Dam stands as a key infrastructure in Knox, Missouri. While not federally regulated, the dam's low hazard potential and considerable storage capacity highlight its importance in supporting various water-related activities in the area. As climate change continues to impact water resources, monitoring and maintaining structures like Wamsley Lake Dam will be crucial for ensuring sustainable water management practices in the region.

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.
