Summary
Built in 1948, it serves multiple purposes including fire protection, stock, and small fish pond. The dam stands at a height of 20 feet and has a storage capacity of 118 acre-feet, with a normal storage level of 33 acre-feet.
Despite being privately owned, Mononame 162 is not regulated or inspected by the state, and has a low hazard potential. The dam has not been rated for its condition assessment, and there is no emergency action plan in place. With a drainage area of 22 square miles, the dam covers a surface area of 11 acres and plays a crucial role in water resource management in the region.
Water resource and climate enthusiasts will find Mononame 162 an intriguing structure due to its historical significance and diverse functionality. Its location along the Little Platte River adds to its ecological value, providing essential services for fire protection, livestock, and aquatic life. As a privately owned earth dam, Mononame 162 serves as a symbol of human ingenuity in harnessing natural resources for multiple purposes while also highlighting the importance of proper maintenance and regulatory oversight to ensure safety and sustainability for the surrounding community and environment.

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.
