Summary
Built in 1960, this dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a height of 15 feet and a length of 350 feet, Mr Pp has a storage capacity of 62 acre-feet, with a normal storage level of 32 acre-feet. The dam is situated on TR-Big Dry Creek and is regulated by the Montana Department of Natural Resources and Conservation (DNRC).
Despite being classified as having a low hazard potential, the condition assessment of Mr Pp is currently listed as "Not Rated." This suggests that further evaluation may be required to ensure the safety and integrity of the dam. While no inspection date or frequency is provided, the dam does have state-regulated permitting, inspection, and enforcement in place. Additionally, Mr Pp does not fall under the jurisdiction of the US Army Corps of Engineers, indicating that all regulatory oversight and management of the dam lies with state agencies.
For water resource and climate enthusiasts, Mr Pp presents an intriguing case study of a privately owned earth dam in rural Montana. Its multi-purpose design and location on TR-Big Dry Creek highlight the importance of small-scale water infrastructure in supporting local communities and ecosystems. The lack of a condition rating raises questions about the ongoing maintenance and safety of the dam, underscoring the need for regular inspections and risk assessments to mitigate potential hazards. As climate change continues to impact water resources, understanding the condition and management of dams like Mr Pp is crucial for ensuring their resilience in the face of evolving environmental conditions.

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.
