Summary

The dam stands at a height of 16 feet and has a length of 278 feet, providing a storage capacity of 56 acre-feet. With a surface area of 7 acres and a drainage area of 1.8 square miles, the dam plays a crucial role in controlling water flow and ensuring water availability for various purposes in the region.

Managed by the Nebraska Department of Natural Resources, Monie Dam is regulated, inspected, and enforced by the state to ensure its structural integrity and safety. Despite being classified as having a low hazard potential, the dam's condition assessment in 2020 was deemed unsatisfactory, highlighting the need for maintenance and potential improvements. With a history of serving as a vital water resource for the area, the dam continues to play a crucial role in water management and conservation efforts along the TR Republican River.

As a key feature in the local water infrastructure, Monie Dam serves as a critical asset for fire protection, livestock watering, and recreational activities in the region. With its strategic location and capacity to store water, the dam contributes to the overall ecosystem health and resilience, making it a significant resource for both human and environmental needs. Ongoing inspections and regulatory oversight by the Nebraska DNR ensure that the dam remains safe and functional, underscoring its importance in water resource management and climate adaptation strategies for the future.

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.
