Summary
The dam, designed by USDA NRCS, serves the primary purpose of flood risk reduction along the East Fork Grand River. With a height of 27 feet and a length of 575 feet, the dam has a normal storage capacity of 45 acre-feet and a maximum storage of 149 acre-feet.
Situated in a low hazard potential area, the East Fork Grand River Dam C-40 is classified as having a moderate risk level. The dam is primarily made of earth and stone materials with a soil foundation. The structure has uncontrolled spillways and outlet gates. Despite not having a formal condition assessment, the dam is regularly inspected and deemed to be in satisfactory condition.
Managed by the Natural Resources Conservation Service, the East Fork Grand River Dam C-40 plays a crucial role in protecting the surrounding area from potential flooding events. With its strategic location and design, the dam effectively reduces the risk of flood damage and ensures the safety of the community in Denver, Missouri.

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.
