Summary
The dam stands at a height of 15 feet and spans 110 feet in length, with a storage capacity of 92 acre-feet. Situated on TR-Sevenmile Creek, it serves as a critical water resource for the surrounding area.
Despite being classified as having a low hazard potential, Raymond (Phillips) is considered to have a moderate risk level. With a drainage area of 0.53 square miles and a maximum discharge of 100 cubic feet per second, the dam plays a crucial role in managing water flow and providing essential water resources. While the dam's condition assessment is currently not rated, its state-regulated status ensures that regular inspections, permitting, and enforcement measures are in place to maintain its integrity and safety standards.
Managed by the DNRC in Congressional District 00, Montana, Raymond (Phillips) is a vital component of the local water infrastructure. Its uncontrolled spillway and proximity to Saco highlight the importance of this structure in mitigating flood risks and ensuring water security for the community. For water resource and climate enthusiasts, Raymond (Phillips) offers a fascinating case study in dam management and the intersection of water conservation and public safety.

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.
