Summary
Built in 1930, this earth dam boasts a height of 10 feet and a length of 125 feet, with a storage capacity of 64 acre-feet. Despite its age, Cancer dam is categorized as having a low hazard potential and is regulated by the Montana Department of Natural Resources and Conservation (DNRC).
Situated along the TR-ROCKY COULEE stream, Cancer dam plays a key role in water management in the region, providing essential services for the local community in LOMA. Despite its modest size, the dam's impact on the surrounding ecosystem and water availability cannot be understated. With a focus on fire protection and sustaining livestock and fish populations, Cancer dam serves as a crucial piece of infrastructure in the area.
Managed by a private entity, Cancer dam undergoes regular inspections and maintenance to ensure its structural integrity and functionality. While its condition is currently marked as "Not Rated," the dam continues to serve its purpose effectively. With its history dating back to the early 20th century, Cancer dam stands as a testament to the importance of water resources and climate management in sustaining local ecosystems and communities.

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.
