Summary
Built in 1948 for irrigation purposes, this dam stands at a height of 15 feet and has a storage capacity of 69 acre-feet. Situated on the TR-PLUM COULEE river or stream, Saucer #1 is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is subject to state jurisdiction, permitting, inspection, and enforcement.
Despite its low hazard potential, Saucer #1 has not been rated for its condition assessment. The dam has not undergone recent inspections, and information on emergency action plans and risk management measures is not available. The dam does not fall under the jurisdiction of the U.S. Army Corps of Engineers (USACE), and there are no associated structures or locks with the dam. Saucer #1 presents an interesting case study for water resource and climate enthusiasts interested in the management and maintenance of older irrigation infrastructure.
Overall, Saucer #1 serves as a reminder of the importance of regular inspections and maintenance for aging dams, especially those used for irrigation purposes. With its historical significance and unique characteristics, this earth dam in Montana offers valuable insights into the challenges and considerations involved in preserving and managing water resources in a changing climate.

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.
