Summary
Completed in 1960, this state-owned dam stands at a height of 8 feet with a length of 300 feet, providing a maximum storage capacity of 88 acre-feet. Situated on the SOUTH FORK SIMMS CREEK, Blooming Creek Dam plays a crucial role in water management and conservation in the region.
With a low hazard potential and a condition assessment that has not been rated yet, Blooming Creek Dam is regulated, inspected, and enforced by the Montana Department of Natural Resources and Conservation (DNRC). The dam's emergency action plan (EAP) status and risk assessment measures are currently not available, highlighting the need for updated safety protocols and risk management strategies to ensure the continued safety of the surrounding community and environment. Despite its low hazard potential, the dam's importance in providing essential water resources for various uses underscores the importance of regular inspections and maintenance.
As a vital component of water resource management in Cascade County, Montana, Blooming Creek Dam represents a key infrastructure for ensuring water availability for fire protection, livestock, and recreational purposes. With its earth dam structure and modest storage capacity, the dam serves as a reliable source of water in the region. As climate change continues to impact water resources, the maintenance and safety of Blooming Creek Dam will be crucial in mitigating potential risks and ensuring sustainable water management practices for the future.

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.
