Summary
Completed in 1972, this earth dam stands at 15 feet high and stretches for 600 feet, serving multiple purposes including fire protection, stock, and small fish pond management. With a storage capacity of 54 acre-feet, Deuteronomy is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is maintained for low hazard potential.
Despite its modest size and purpose, Deuteronomy plays a crucial role in the local ecosystem by providing water for fire protection and supporting livestock and aquatic life. As a privately owned structure, it is subject to state jurisdiction, permitting, inspection, and enforcement to ensure its safe operation and compliance with regulations. Although its condition is currently not rated, regular inspections and potential emergency action plans are in place to address any unforeseen risks and ensure the structure's integrity for the community it serves.
In the vast landscape of Montana, Deuteronomy stands as a testament to the importance of small-scale water management for both practical and ecological purposes. With a focus on sustainability and safety, this earth dam embodies the balance between human needs and environmental stewardship, contributing to the resilience of the local community 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.
