Summary

The dam stands at a height of 19 feet and has a storage capacity of 71 acre-feet, with a normal storage of 35 acre-feet. It is situated on TR Brushy Branch Creek and falls under the jurisdiction of the Kansas City District of the US Army Corps of Engineers.

Despite being classified as having a low hazard potential, Mononame 102's condition assessment is listed as "Not Rated" and it lacks recent inspection and emergency preparedness data. The dam, with a surface area of 7 acres and drainage area of 93 acres, serves as a vital water resource for the surrounding area. As water resource and climate enthusiasts, it is crucial to monitor and assess the condition of structures like Mononame 102 to ensure their safety and longevity in the face of changing environmental conditions.

With a lack of regulatory oversight and maintenance data, Mononame 102 presents an opportunity for further investigation and assessment by relevant agencies and stakeholders. As water resources continue to face challenges from climate change and increased demand, ensuring the safety and functionality of dams like Mononame 102 is essential for maintaining a sustainable water supply for the community. It is imperative for water resource enthusiasts to advocate for proper monitoring and maintenance of vital infrastructure like Mononame 102 to safeguard against potential risks and ensure the continued availability of this important water source.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
