Summary
Completed in 1966, this dam stands at a height of 28 feet and has a storage capacity of 110 acre-feet. With a drainage area of 2.63 square miles and a maximum discharge of 1250 cubic feet per second, Neufeld No 1 plays a crucial role in managing water flow in the region.
Despite being categorized as having a low hazard potential and a moderate risk assessment, Neufeld No 1 has not been rated for its condition assessment. The dam features an uncontrolled spillway with a width of 200 feet, and it is regulated and inspected by the Montana Department of Natural Resources and Conservation (DNRC). With its strategic location and purposeful design, Neufeld No 1 stands as a vital infrastructure for water resource management and climate resilience in Valley County, Montana.
As a key component of the flood risk reduction strategy in the area, Neufeld No 1 serves as a testament to the collaborative efforts between private owners, federal agencies, and state regulators in safeguarding against potential water-related disasters. With its long history of service since its construction in 1966, this dam continues to play a crucial role in protecting the local community and environment from the impacts of flooding, showcasing the importance of proactive water resource management in a changing climate scenario.

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.
