Summary
Built in 1953 by the USDA NRCS, this dam stands at 18 feet tall with a length of 275 feet and a storage capacity of 77 acre-feet. Situated on TR-Little Porcupine Creek, this structure is regulated by the DNRC and is inspected, permitted, and enforced by the state of Montana.
Despite being categorized as having a low hazard potential, Standish #4 is deemed to have a moderate risk assessment, indicating potential issues that may require management measures in the future. With a condition assessment that is currently not rated, the dam's risk factors and emergency action plans may need to be revisited and updated as necessary. While the dam has not been modified in recent years and lacks specific details on inspections and maintenance, its location in Cartersville and close proximity to the Omaha District make it a significant water resource for the region.
Overall, Standish #4 presents an intriguing case study for water resource and climate enthusiasts, showcasing the intricate management and regulatory framework surrounding private dams in Montana. With its historical significance dating back to the 1950s and its diverse range of purposes, this structure highlights the importance of proper maintenance and risk assessment in ensuring the safety and sustainability of water resources in the region. As climate change continues to impact water availability and quality, understanding the complexities of dam infrastructure like Standish #4 is crucial for informed decision-making and effective resource management.

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.
