Summary
is a privately owned earth dam located in Hill, Montana, near the city of Havre. Built in 1948 for fire protection, stock, and small fish pond purposes, this dam stands at a height of 20 feet and stretches 300 feet in length. With a storage capacity of 155 acre-feet, it primarily serves the needs of the local community while also contributing to the management of the Sprinkle Coulee river system. Despite being classified as having a low hazard potential, the dam's condition is currently not rated.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Pasma, J. is subject to state regulations, permitting, inspection, and enforcement. The dam is situated within Congressional District 00 of Montana and falls under the jurisdiction of the Omaha District of the US Army Corps of Engineers. While the dam has not undergone recent assessments or inspections, it remains operational and serves its intended purposes effectively. As a vital infrastructure for water resource management in the region, Pasma, J. plays a crucial role in supporting local agriculture, fire protection, and ecological sustainability.
As a key component of the water management system in the area, Pasma, J. contributes to the overall resilience of the local environment and community against potential water-related challenges. While its current condition assessment is unavailable, the dam's low hazard potential suggests a stable and safe infrastructure for the surrounding area. With its historical significance dating back to 1948, Pasma, J. stands as a testament to the importance of sustainable water resource management and climate adaptation strategies in Montana's evolving landscape.

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.
