Summary
Built in 1955 by the USDA NRCS, this dam stands at a height of 14 feet and has a storage capacity of 54 acre-feet. Situated along the TR-North Fork McGuire Creek, Wayne #2 is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is subject to state permitting, inspection, and enforcement.
Despite its low hazard potential and current "Not Rated" condition assessment, Wayne #2 plays a crucial role in the local water resource management and climate resilience efforts. While not federally owned or funded, the dam is monitored by the Natural Resources Conservation Service and complies with state jurisdiction and regulatory requirements. With a primary focus on providing water for fire protection and livestock, Wayne #2 contributes to the overall ecosystem health and water security in the area.
As an essential infrastructure for the surrounding community, Wayne #2 highlights the importance of private dams in sustaining water resources and supporting various ecosystem functions. Its location in a remote area of Montana underscores the critical role that small-scale dams play in mitigating the impacts of drought, wildfires, and other climate-related challenges. By adhering to state regulations and inspections, Wayne #2 exemplifies responsible dam management practices that benefit both human and environmental well-being.

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.
