Summary
Completed in 1970, this earth dam stands at 20 feet high with a length of 1000 feet, providing a storage capacity of 498 acre-feet. The dam is classified as having a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment.
Situated in a rural area, Green #4 serves the primary purpose of irrigation and is regulated by the Montana Department of Natural Resources and Conservation (DNRC). Despite being privately owned, the dam falls under state jurisdiction, with permitting, inspection, and enforcement processes in place to ensure its safety and compliance with regulations. The surrounding area is represented in Congress by Greg Gianforte (R) in Montana's Congressional District 00.
For water resource and climate enthusiasts, Green #4 offers insight into the management of irrigation infrastructure in rural Montana. With its low hazard potential and regulatory oversight, this dam serves as a vital resource for agricultural activities in the region, highlighting the importance of maintaining and monitoring water resources in the face of changing climate conditions.

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.
