Summary
It is situated along the Trib Calvey Creek and is under the jurisdiction of the Kansas City District of the US Army Corps of Engineers. The dam has a height of 30 feet and a storage capacity of 112 acre-feet, with a normal storage level of 70 acre-feet. It covers a surface area of 7 acres and has a drainage area of 350 acres.
Despite not being regulated by the state, Mo No Name has a high hazard potential due to its condition being "Not Rated" and lacking a formal Emergency Action Plan (EAP). The dam poses a risk to the surrounding area in case of failure, highlighting the importance of regular inspections and maintenance to ensure its safety. With its proximity to residential areas and the potential impact on the environment, there is a need for increased monitoring and risk management measures for this structure.
Water resource and climate enthusiasts can appreciate the significance of Mo No Name as a key infrastructure supporting the local water supply and ecosystem. By understanding its design and purpose, as well as its associated risks, stakeholders can work towards safeguarding this important asset and enhancing its resilience in the face of changing climate patterns and increasing water demands.

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.
