Summary
Constructed in 1960 by the USDA NRCS, this Earth-type dam stands at a height of 30 feet and has a length of 200 feet, providing a storage capacity of 31 acre-feet. The dam serves the primary purpose of irrigation, with a maximum discharge of 100 cubic feet per second and a drainage area of 3.41 square miles.
Owned and regulated by private entities, Indian Judy is subject to state jurisdiction and oversight by the DNRC. Despite being classified as having a low hazard potential and not yet rated for condition assessment, the dam plays a crucial role in water resource management in the region. With its strategic location in the heart of Montana, Indian Judy represents a vital piece of infrastructure for agricultural activities and water supply in the area.
As an important water management structure in the region, Indian Judy highlights the intricate balance between human development and environmental sustainability. With its modest storage capacity and low hazard potential, the dam showcases the essential role of small-scale irrigation projects in supporting local agriculture while also emphasizing the need for ongoing inspection and maintenance to ensure the safety and efficiency of water resource infrastructure in a changing climate.

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.
