Summary
This earth dam was completed in 1949 and serves multiple purposes including fire protection, stock, and small fish pond maintenance. With a dam height of 15 feet and a storage capacity of 69 acre-feet, it provides necessary water resources for the surrounding area.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Jensen No 3 has been deemed to have low hazard potential and is currently in a not rated condition assessment. The dam is regularly inspected, permitted, and enforced by state regulatory agencies to ensure its safety and functionality. Situated in Congressional District 00, Montana, this water resource plays a crucial role in the local ecosystem and agriculture.
Despite its low hazard potential, Jensen No 3 remains a vital asset in maintaining the water supply for fire protection and livestock in the region. As climate change continues to impact water resources, it is essential to monitor and manage such water infrastructure to ensure its resilience in the face of changing environmental conditions. With state jurisdiction and regulatory oversight, Jensen No 3 (Dawson) exemplifies the importance of sustainable water resource management in the face of a changing climate.

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.
