Summary

Built in 1950, this Earth dam stands at a height of 20 feet and has a storage capacity of 82 acre-feet, primarily serving purposes such as fire protection, stock watering, and a small fish pond. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is classified as having a low hazard potential.

Situated in the Omaha District, Looney Tuney is a vital resource for diffused surface water management in the area. With a maximum storage capacity of 82 acre-feet and a normal storage of 42 acre-feet, the dam plays a crucial role in ensuring water availability for various needs. While the condition of the dam is currently rated as "Not Rated," its importance in providing essential services like fire protection highlights its significance in the local ecosystem.

Despite its low hazard potential, Looney Tuney remains a key asset in maintaining water resources and supporting local wildlife in Toole County. As a private structure, it stands as a testament to the collaboration between private owners and state regulatory agencies in managing water infrastructure for the benefit of the community. The dam's historical significance, coupled with its functional importance, makes it a valuable asset for water resource and climate enthusiasts seeking to understand the intricate balance between human intervention and natural ecosystems.

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.
