Summary
Built in 1962, this earth dam stands at a height of 18 feet, providing a storage capacity of 96 acre-feet. While it has a low hazard potential, the dam's condition assessment is currently not rated, indicating a need for further evaluation.
Although not regulated by the state, Mononame 800 offers a peaceful retreat for water resource and climate enthusiasts with its surface area of 10 acres and a normal storage capacity of 30 acre-feet. The dam's buttress core type and unlisted foundation contribute to its structural integrity, while its location in Webster County adds to its scenic charm. Despite its age, the dam continues to be a popular spot for outdoor activities such as fishing and boating.
With its recreational primary purpose and historical significance as a local landmark, Mononame 800 stands as a testament to the enduring appeal of water resources in the heart of Missouri. As efforts to assess and manage its condition evolve, this dam remains a valuable asset for the community and a reminder of the importance of preserving our natural environment for future generations.

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.
