Summary
This earth dam, standing at a height of 34.8 feet, with a hydraulic height of 34 feet, and a structural height of 36 feet, plays a vital role in protecting the surrounding area from potential flooding events. With a normal storage capacity of 34 acre-feet and a maximum storage capacity of 84 acre-feet, the dam covers a surface area of 4 acres and drains an area of 140.16 square miles.
Despite its low hazard potential and moderate risk assessment rating, East Fork Grand River Dam F-68 has not been fully assessed for its condition. The dam features an uncontrolled spillway and outlet gates, ensuring effective water discharge during high flow events. Although it has not undergone recent inspections, the structure meets flood risk reduction purposes and remains under the jurisdiction of the local government in Harrison County, Missouri. With no state regulation or permitting requirements, the dam serves as a critical infrastructure for the community in managing water resources and climate-related challenges.
In the event of emergencies, the dam is equipped with emergency action plans; however, the last assessment date is unknown, highlighting the need for regular maintenance and inspection. Managed by the Natural Resources Conservation Service, East Fork Grand River Dam F-68 stands as a testament to strategic flood risk reduction efforts in the region, showcasing the importance of sustainable water resource management practices in mitigating the impacts of climate change.

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.
