Summary
Completed in 1975, this earth dam stands at a height of 36 feet and spans a length of 850 feet, with a storage capacity of 990 acre-feet. The dam plays a crucial role in protecting the surrounding communities from potential flooding events, showcasing a high hazard potential but maintaining a satisfactory condition assessment as of the last inspection in 2007.
Managed by the local government and regulated by the DAM AND RESERVOIR SAFETY PROG of Missouri, the 102 River Tributaries Dam C-5 serves multiple purposes including flood risk reduction and recreation. The dam's spillway, with a width of 100 feet, helps control the flow of water during peak discharge periods. With a drainage area of 1401 square miles, the dam is strategically located along the Canal Branch of the 102 River, providing essential water resource management for the region. Despite its age, the dam continues to meet regulatory standards and remains a critical infrastructure for water resource and climate enthusiasts in the area.

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.
