Summary
This earth dam stands at 18 feet tall and spans 250 feet in length, with a storage capacity of 51 acre-feet. Situated on TR-Porcupine Creek, the dam is regulated by the Montana Department of Natural Resources and Conservation, ensuring its safety and compliance with state regulations.
With a low hazard potential and a current condition assessment of "Not Rated," Bobsland Dam serves as a vital resource for the local community. Although the dam's inspection frequency and emergency preparedness details are not specified in the data, its importance in providing essential water resources for fire protection and livestock needs cannot be understated. As climate change continues to impact water availability and quality, the upkeep and maintenance of dams like Bobsland become increasingly crucial in ensuring sustainable water management practices.
As enthusiasts of water resources and climate issues, it is important to recognize the role that dams like Bobsland play in addressing local water needs and supporting ecosystem health. By staying informed about the regulatory oversight, emergency preparedness, and risk management measures associated with such structures, we can advocate for responsible water resource management practices and contribute to the preservation of our natural environment for future generations.

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.
