Summary
This earth dam stands at a height of 35 feet and spans 485 feet in length, serving primarily for flood risk reduction along the East Fork of Grand River. With a storage capacity of 128 acre-feet and a drainage area of 332.8 square miles, the dam plays a crucial role in managing water flow and minimizing potential hazards in the region.
The dam, classified as having a low hazard potential and a moderate risk level, features an uncontrolled spillway with a width of 30 feet. Despite being in operation for nearly two decades, the condition assessment of the dam has not been rated, emphasizing the need for regular inspections and maintenance to ensure its structural integrity. With no associated structures and no state regulation or permitting requirements, East Fork Grand River Dam C-26 remains a vital component in the local flood management infrastructure, safeguarding the surrounding area from potential inundation events.
As an essential part of the flood risk reduction strategy in Worth County, Missouri, East Fork Grand River Dam C-26 plays a crucial role in protecting the community from water-related disasters. With its strategic location along the East Fork of Grand River and a storage capacity of 128 acre-feet, the dam serves as a reliable barrier against potential flooding events. However, the lack of a recent condition assessment and the moderate risk level indicate the importance of continued monitoring and maintenance to ensure the dam's effectiveness in safeguarding 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.
