Summary
Built in 1967, this earth dam stands at a height of 20 feet and serves primarily for recreational purposes. With a storage capacity of 107 acre-feet, the dam covers a surface area of 10 acres and drains a watershed area of 673 square miles.
Despite its low hazard potential and current "Not Rated" condition assessment, Mononame 25 lacks certain regulatory oversight as it is not state-regulated and does not require permitting, inspection, or enforcement. The dam's emergency action plan (EAP) status is also unspecified, raising questions about its preparedness for potential risks and disasters. With no associated structures or locks, and a spillway width of zero, the dam's safety and maintenance practices may need further evaluation to ensure the protection of downstream communities and the surrounding environment.
Water resource and climate enthusiasts may find Mononame 25's unique characteristics and limited regulatory oversight intriguing, as it highlights the diverse landscape of dam infrastructure across the United States. The dam's location in Atchison County, Missouri, under the jurisdiction of the Kansas City District, adds to its appeal for those interested in studying the intersection of water management, infrastructure development, and environmental conservation. Further research into Mononame 25's historical modifications, risk assessment, and emergency preparedness measures could provide valuable insights into the complexities of managing dams in rural areas with varying levels of oversight and regulation.

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.
