Summary
Built in 1930, this earth dam stands at a height of 20 feet and has a storage capacity of 53 acre-feet, primarily serving purposes such as fire protection, stock water, and small fish pond maintenance. Situated on TR-Dodson Creek, Herman #1 is regulated by the Montana Department of Natural Resources and Conservation (DNRC), ensuring regular inspections and enforcement of safety measures.
With a low hazard potential and a current condition assessment of "Not Rated," Herman #1 continues to play a crucial role in water resource management in the region. Although lacking in certain data points such as inspection dates and emergency action plan updates, the dam remains a vital infrastructure for the local community. Additionally, situated within Congressional District 00, Montana, Herman #1 falls under the jurisdiction of Representative Greg Gianforte (R), highlighting its significance in the broader political landscape.
Water resource and climate enthusiasts will find Herman #1 to be a fascinating example of early 20th-century dam construction, offering insight into the historical development of water infrastructure in rural Montana. As efforts to address climate change intensify, understanding the role of such structures in water management becomes increasingly important. Herman #1 serves as a reminder of the ongoing need for sustainable water resource practices and the critical role that private dams play in supporting various community needs.

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.
