Summary
Completed in 1942 for purposes such as fire protection, stock, and small fish pond, this dam stands at a height of 24 feet and has a storage capacity of 62 acre-feet. With a low hazard potential and a current condition assessment of "Not Rated," Raise #1 is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is subject to state permitting, inspection, and enforcement.
Situated in a scenic area within Dawson County, Raise #1 serves as a vital infrastructure for water resource management in the region. The dam's primary purpose of fire protection underscores its importance in safeguarding the local community and ecosystem. Although the dam's condition assessment is currently "Not Rated," its low hazard potential signifies minimal risk to downstream areas. The involvement of the DNRC in regulating and inspecting Raise #1 ensures its compliance with state standards and enhances its overall safety and functionality.
As a historical structure built over 80 years ago, Raise #1 represents a significant piece of Montana's water resource infrastructure. Its location along the Thirteenmile Creek and its contribution to water storage and management highlight its role in supporting various activities in the area. With a storage capacity of 62 acre-feet and a height of 24 feet, this earthen dam continues to serve its intended purposes while being subject to state oversight and regulatory measures to ensure its continued safety and reliability.

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.
