Summary
Completed in 1935, this Earth dam stands at a height of 15 feet and serves multiple purposes such as fire protection, stock watering, and as a small fish pond. With a storage capacity of 50 acre-feet, it primarily holds 24 acre-feet of water under normal conditions. The dam has a low hazard potential and has not been rated for its current condition.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Incorporeal is regulated, inspected, and enforced by the state agency, ensuring its compliance with safety and environmental standards. Located in Chouteau County, this reservoir provides vital water resources for the local community and surrounding areas. The dam's primary function in fire protection highlights its importance in safeguarding the region against potential wildfires.
Despite its modest size, Incorporeal plays a crucial role in water management and conservation efforts in the area. As climate change continues to impact water resources, the presence of structures like Incorporeal becomes increasingly vital for ensuring water availability and security in the face of changing environmental conditions. Its historical significance and continued operation underscore the importance of sustainable water resource management in the region.

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.
