Summary
Built in 1975, the dam serves multiple purposes, including fire protection, stock, and small fish pond management. With a height of 25 feet and a storage capacity of 86 acre-feet, Nollmeyer #1 has a low hazard potential and is regulated by the Montana Department of Natural Resources and Conservation (DNRC). The dam has not been rated for its current condition and does not have an Emergency Action Plan (EAP) in place.
Despite its relatively small size, Nollmeyer #1 plays a crucial role in water resource management in the region. Its location in Park County, Montana, makes it an important asset for maintaining water supply for various uses, especially in times of fire emergencies. The dam's presence also contributes to the overall ecosystem health of TR-Elk Creek and supports the local wildlife population. As a privately owned structure, Nollmeyer #1 is subject to state jurisdiction and regulation, ensuring its safe operation and maintenance.
Water resource and climate enthusiasts will appreciate the significance of Nollmeyer #1 as a key infrastructure for water management in Montana. Its construction and purpose reflect the importance of sustainable water practices and the need for effective dam regulation and inspection. As part of the larger network of dams in the area, Nollmeyer #1 highlights the interconnectedness of water resources, climate resilience, and environmental stewardship in maintaining a balanced ecosystem for both human and wildlife communities.

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.
