Summary
Built in 1910 for fire protection, stock, and small fish pond purposes, this dam stands at a height of 10 feet and has a storage capacity of 217 acre-feet. With a significant hazard potential and no current condition rating, Staff #1 plays a crucial role in ensuring the water security and safety of the surrounding area.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Staff #1 is subject to state regulations, permitting, inspection, and enforcement. Although its condition assessment is currently not rated, the dam's location in the Lohman area and its proximity to the city highlight its importance in water resource management. With a history dating back over a century, Staff #1 serves as a vital infrastructure for the local community and ecosystem.
As an enthusiast of water resources and climate, one can appreciate the historical significance and functional importance of Staff #1. Its presence not only supports fire protection and agricultural activities but also contributes to the ecological balance of the region. With its status as a privately owned structure and its role in maintaining water storage and supply, Staff #1 exemplifies the intersection of human intervention and natural resource management in Montana's water landscape.

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.
