Summary
The earth dam, with a height of 10 feet and a length of 500 feet, was completed in 1960 and has a storage capacity of 79 acre-feet. Situated along the Sawmill Ditch, the pond serves as a vital water source for agricultural activities in the area. Despite its low hazard potential, the dam's condition is currently not rated, highlighting the need for regular inspections and maintenance to ensure its continued safety and functionality.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Blanchard Pond falls under state jurisdiction and is subject to state regulations, permitting, inspection, and enforcement. Although it has not undergone a recent condition assessment, the pond's emergency action plan (EAP) status, inundation maps, risk assessment, and risk management measures remain unspecified. With its location in a pristine natural setting, this water resource serves as a crucial component of the local ecosystem, supporting wildlife habitats and enhancing the overall environmental quality of the region.
As a key feature in the water infrastructure of the region, Blanchard Pond plays a significant role in sustaining agricultural activities and contributing to water resource management in the area. Its historical significance, dating back to the 1960s, underscores its importance as a longstanding resource for the community. With ongoing monitoring and maintenance efforts, this reservoir will continue to serve as a valuable asset for irrigation purposes while also promoting the conservation and sustainable use of water resources in Beaverhead County, Montana.

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.
