Summary
Site Ca-173-1, located in Galt, Missouri, is a Grade Stabilization earth dam constructed in 1977 on TR-Little Medicine Creek. The dam stands at a height of 27 feet and has a hydraulic height of 26 feet, serving the primary purpose of Grade Stabilization. With a drainage area of 51.2 square miles and a maximum discharge of 390 cubic feet per second, this low-hazard dam plays a crucial role in managing water resources in Mercer County.
Although the dam has a normal storage capacity of 3 acre-feet and a maximum storage capacity of 103 acre-feet, it covers a surface area of only 1 acre. Despite its small size, Medicine Twp. Site Ca-173-1 plays a significant role in mitigating flood risks in the area. With an uncontrolled spillway width of 50 feet, the dam is designed to handle moderate risk levels. This site, under the jurisdiction of the Rock Island District of the US Army Corps of Engineers, serves as a valuable asset for water resource and climate enthusiasts interested in the management of dams and water flow in the region.

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.
