Summary
Completed in 1962, this earth dam stands at a height of 20 feet and has a storage capacity of 146 acre-feet, primarily serving purposes such as fire protection, stock, and small fish pond management. Despite being under state jurisdiction and regulation by the Department of Natural Resources and Conservation (DNRC), Gilda Radner has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
With its tranquil setting and functional design, Gilda Radner offers a vital water resource infrastructure for the local community, ensuring reliable water storage for various purposes. While the dam has not been inspected in recent years and lacks detailed risk assessment measures, its emergency action plan status and adherence to guidelines remain unknown. Situated in an area represented by Congressman Greg Gianforte, the dam presents a significant asset for water management in Phillips County, Montana.
For water resource and climate enthusiasts, Gilda Radner serves as a noteworthy example of state-managed infrastructure supporting multiple beneficial uses. While its condition assessment and emergency preparedness aspects require further evaluation, the dam's historical significance and essential role in water storage for fire protection and agricultural activities highlight the importance of sustainable water management in the region. As climate change impacts become more pronounced, understanding and maintaining dams like Gilda Radner will be crucial for ensuring water security and resilience in the face of evolving environmental challenges.

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.
