Summary
Built in 1960 for irrigation purposes, the dam stands at a height of 20 feet and has a storage capacity of 83 acre-feet. Despite its age, the dam is classified as having a low hazard potential and has not been rated for its condition.
With the state regulatory agency DNRC overseeing its permitting, inspection, and enforcement, Balsam #4 is in compliance with state jurisdiction and regulations. The dam has not undergone any modifications or inspections in recent years, and its emergency preparedness and risk assessment measures are currently not updated. Located in a picturesque setting in Custer County, Montana, the dam serves as a vital water resource for agricultural irrigation in the area.
Although Balsam #4 may not be a particularly large or high-profile dam, its role in supporting irrigation in the region cannot be underestimated. As water resource and climate enthusiasts, understanding the infrastructure and management of such structures is crucial in ensuring sustainable and effective water use in the face of changing environmental conditions.

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.
