Summary
This private earth dam stands at a height of 33 feet, with a hydraulic height of 33 feet and a structural height of 35 feet. With a length of 900 feet and a storage capacity of 660 acre-feet, this dam plays a crucial role in managing floodwaters and protecting the surrounding area from potential inundation.
The Chillicothe Rc&D Flood Prevention Structure boasts a spillway width of 100 feet and a maximum discharge capacity of 3,337 cubic feet per second, ensuring effective water flow management during periods of increased rainfall and potential flooding. While the dam's hazard potential is rated as high, its risk assessment is considered moderate, with a DSAC assigned date yet to be determined. Despite its high hazard potential, the dam's condition assessment is currently listed as "Not Rated," indicating a need for further evaluation and maintenance to ensure its continued effectiveness in flood prevention and risk reduction efforts.
As an integral part of flood risk reduction initiatives in Livingston County, Missouri, the Chillicothe Rc&D Flood Prevention Structure serves as a vital asset in protecting the local community from the devastating impacts of flooding. While its condition assessment and risk management measures may require further attention, the dam's strategic location and design make it a key player in ensuring the safety and well-being of residents and infrastructure along the TR-Grand River. With its impressive storage capacity and hydraulic capabilities, this structure stands as a testament to the importance of proactive flood prevention measures in the face of changing climate patterns and increasing water resource challenges.

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.
