Summary
With a height of 24 feet and a length of 855 feet, this earth dam serves the primary purpose of irrigation, providing a storage capacity of 55 acre-feet. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is inspected and enforced by the state agency to ensure its safety and compliance with regulations.
Despite being classified as low hazard potential and currently assessed as "Not Rated" in condition, Peters #2 plays a crucial role in supporting agricultural activities in the region. The dam's normal storage capacity of 28 acre-feet allows for water to be efficiently stored and utilized for irrigation purposes, contributing to the sustainability of farming practices in the area. As a part of the state jurisdiction, Peters #2 undergoes regular inspections and permitting processes to maintain its functionality and safety standards.
Located in the Congressional District 00 of Montana, Peters #2 stands as a testament to the importance of water resource management in sustaining agricultural activities in the region. With its strategic location on TR-Box Elder Creek and its role in irrigation, this dam serves as a vital infrastructure asset for the local community. As water resource and climate enthusiasts, understanding the significance of dams like Peters #2 in supporting agricultural sustainability and water management practices is essential for promoting environmental stewardship and resilience 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.
