Summary
Built in 1928, this dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a height of 12 feet and a length of 150 feet, the dam has a storage capacity of 64 acre-feet and a low hazard potential.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Schoolhouse #2 is regulated and inspected by the state to ensure its safety and compliance with regulations. Despite being in operation for almost a century, the dam's condition assessment is currently marked as "Not Rated," indicating a need for further evaluation. While the dam has not been modified in recent years and has not undergone a risk assessment, it is still considered to meet guidelines for emergency action planning.
Situated in a picturesque rural setting, Schoolhouse #2 offers a glimpse into the historical significance of water resource management in the region. As climate change continues to impact water availability and quality, the maintenance and monitoring of such structures become increasingly important for sustainable water management practices in the face of evolving environmental challenges.

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.
