Summary
Built in 1945 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock watering, and small fish pond management. With a dam height of 23 feet and a length of 300 feet, Binion #3 has a storage capacity of 243 acre-feet and a drainage area of 1.41 square miles.
The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is classified as having a significant hazard potential with a moderate risk rating. The spillway, with a width of 100 feet, is uncontrolled, and the dam has never been inspected or rated for its condition. Despite the lack of recent assessments, Binion #3 remains a crucial water resource infrastructure for the surrounding area, providing essential services while also posing potential risks that warrant further evaluation and management.
As a vital component of the local water management system, Binion #3 highlights the importance of regular inspections and maintenance to ensure its continued safety and effectiveness. With its strategic location and significant storage capacity, this dam plays a key role in supporting various water-related activities in the region, emphasizing the need for ongoing monitoring and risk management to safeguard both human and environmental interests in the face of changing climate 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.
