Summary
With a height of 15 feet and a storage capacity of 80 acre-feet, this dam serves as a low hazard potential structure with a condition assessment of "Not Rated." Despite its age, Mononame 275 has not undergone any modifications and is not regulated or inspected by the state.
Owned by a private entity, Mononame 275 stands as a testament to the importance of water resource management for recreational activities. Situated in Chariton County, Missouri, this dam is part of the Rock Island District and falls under the jurisdiction of Representative Sam Graves (R). While the dam's primary purpose is for recreation, its impact on the surrounding environment and water systems remains a topic of interest for water resource and climate enthusiasts.
As a structure with a limited risk assessment and no emergency action plan, Mononame 275 represents a unique case study for understanding the intersection of water management, dam safety, and recreational activities. With a storage capacity of 80 acre-feet and a surface area of 10 acres, this dam on Brush Creek provides valuable insights into the challenges and opportunities associated with managing water resources in rural areas.

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.
