Summary
Completed in 1940, this dam stands at a height of 15 feet and has a storage capacity of 151 acre-feet. Situated on the TR-Hay Coulee stream, this structure serves as a vital resource for water management in the area, with a low hazard potential and a state-regulated status.
The dam, with a length of 200 feet, plays a crucial role in maintaining water levels for fire protection, livestock, and recreational purposes. Managed by the Montana Department of Natural Resources and Conservation (DNRC), the dam is subject to state jurisdiction and oversight, including regular inspections to ensure its structural integrity and safety. Despite not being rated for its current condition, Haylodge #2 remains a key component of the local water resource infrastructure, contributing to the overall water management efforts in the region.
With its strategic location in Hill County, Montana, Haylodge #2 is an essential asset for water resource management in the area. While its purpose primarily focuses on fire protection and livestock needs, the dam also serves as a small fish pond, highlighting its versatility and importance in supporting various environmental and agricultural activities. As climate change continues to impact water resources, structures like Haylodge #2 play a crucial role in ensuring sustainable water management practices for the future.

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.
