Summary
This earth dam, completed in 1957, stands at 17 feet tall and spans 450 feet, providing a storage capacity of 54 acre-feet. Situated on TR-Woody Creek, Rey is regulated by the DNRC and falls under the jurisdiction of the state of Montana, with all necessary permitting, inspection, and enforcement mechanisms in place.
Despite its low hazard potential and the absence of a formal condition assessment, Rey serves as a vital water management structure in the region. The dam's location in a remote area with no associated structures underscores its importance for fire protection and stock watering purposes. While it does not fall under the jurisdiction of any federal agency, Rey's presence contributes to the overall water resource management efforts in the state, showcasing the collaboration between private owners and state regulatory agencies in safeguarding water resources for various uses.
With its historical significance dating back to the mid-20th century, Rey stands as a testament to the enduring importance of water management infrastructure in ensuring the sustainability of natural resources. As climate change continues to impact water availability and quality, structures like Rey play a crucial role in mitigating risks and meeting the water needs of both human and ecological communities. The collaboration between state agencies, private owners, and federal designers highlights the multi-stakeholder approach required to address the complex challenges of water resource management in the face of a changing climate.

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.
