Summary
Built in 1970 by the USDA NRCS, this earth dam stands at a height of 20 feet and has a length of 500 feet, providing vital fire protection and small fish pond services to the surrounding area. Situated on the Promised Land Coulee, this dam has a storage capacity of 309 acre-feet and a maximum discharge of 300 cubic feet per second.
Managed by the DNRC, R Schmitz #1 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its moderate risk level, this dam meets regulatory guidelines and has not been modified since its completion. With a spillway width of 30 feet and uncontrolled spillway type, this structure plays a crucial role in water resource management and climate resilience in the region. As a supporter of water enthusiasts and climate activists, R Schmitz #1 continues to serve its purpose effectively and efficiently.
Overall, R Schmitz #1 serves as a key asset in providing essential services for fire protection, stock, and small fish pond maintenance in Blair, Montana. With its strategic location and design by the USDA NRCS, this dam plays a significant role in water management and conservation efforts in the region. As climate change intensifies, the importance of structures like R Schmitz #1 in safeguarding water resources and promoting sustainable practices becomes increasingly crucial for the future.

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.
