Summary
Built in 1960, this dam serves multiple purposes including fire protection, stock watering, and providing a small fish pond. With a height of 25 feet and a length of 600 feet, Damschen #2 has a storage capacity of 35 acre-feet, with a normal storage level of 21 acre-feet.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Damschen #2 is classified as having a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While the dam has not been officially inspected or assessed for its emergency action plan, it meets state regulatory guidelines for permitting, inspection, and enforcement. Located in Congressional District 00 of Montana, Damschen #2 is a vital structure for water resource management in the area.
Enthusiasts interested in water resources and climate change will find Damschen #2 to be a noteworthy structure for its role in providing essential services such as fire protection and stock watering in Petroleum County, Montana. With its historical significance dating back to the 1960s, this dam showcases the importance of private infrastructure in supporting local communities and ecosystems. Further research and monitoring of Damschen #2 will be crucial in understanding its resilience to changing climate conditions and ensuring its continued functionality for years to come.

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.
