Summary
Completed in 1974, this earth dam stands at a height of 24 feet and has a storage capacity of 77 acre-feet. Located on the TR-ELMHURST river, this structure plays a crucial role in providing water resources for the surrounding area while also serving as a habitat for small fish.
Despite its low hazard potential, E Hardy #4 is regulated by the state of Montana and is subject to regular inspections, permitting, and enforcement by the Department of Natural Resources and Conservation (DNRC). The dam has not been rated for its condition assessment, but its emergency action plan status and risk management measures are currently unknown. The dam's geographical coordinates are 45.9459° N and -105.2379° W, making it a key point of interest for water resource and climate enthusiasts in the region.
In the event of an emergency or risk evaluation, it is unclear whether E Hardy #4 has an established emergency action plan, inundation maps, or updated emergency contacts. As a non-USACE structure, it falls under the jurisdiction of state regulatory agencies and is maintained by private owners. With its strategic location on the TR-ELMHURST river and its vital role in providing water for fire protection and livestock, E Hardy #4 serves as a significant landmark for water resource management in the area, emphasizing the importance of sustainable infrastructure for climate resilience.

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.
