Summary
Built in 1973 for fire protection, stock, and small fish pond purposes, this structure stands at a height of 14 feet and has a length of 300 feet, providing a storage capacity of 72 acre-feet. Despite its low hazard potential, the dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and undergoes regular inspections, permitting, and enforcement to ensure its safety and compliance with state regulations.
Situated in Congressional District 00, Montana, Schoolhouse #7 serves as a vital water resource for the surrounding area, holding a normal storage capacity of 26 acre-feet. While the dam's condition assessment is currently listed as "Not Rated," its emergency action plan (EAP) status and risk management measures are not specified in the available data. With its location in a region susceptible to climate variability and water resource challenges, understanding the resilience and management of Schoolhouse #7 is crucial for water resource and climate enthusiasts seeking to address these issues in the local community.
As a privately owned structure with a specific focus on fire protection and water storage, Schoolhouse #7 represents a unique intersection of water resource management and infrastructure development in rural Montana. With its location in a low-hazard area and regulatory oversight by the DNRC, this dam serves as a case study for the importance of proactive maintenance, inspection, and emergency preparedness in safeguarding water resources and ensuring the resilience of critical infrastructure in the face of changing climate conditions.

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.
