Summary

Built in 1936 on the TR-Pumpkin Creek, it stands at 27 feet high and spans 585 feet in length. With a storage capacity of 191 acre-feet, it primarily serves the purpose of irrigation in the area. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is deemed to have a low hazard potential.

Despite its age, Rodgers has not been rated for its condition assessment and lacks emergency action plans and risk assessment measures. However, it is regularly inspected by state authorities and is in compliance with state regulatory requirements for permitting, inspection, and enforcement. Congressman Greg Gianforte represents the area in Congressional District 00, Montana, where Rodgers serves as a vital water resource for agricultural activities in the region. Enthusiasts interested in water resources and climate in Montana will find Rodgers to be a fascinating example of early 20th-century irrigation infrastructure that continues to play a crucial role in sustaining local agriculture.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
