Summary
Situated on TR-Crooked Creek, this dam has a height of 30 feet and a storage capacity of 202 acre-feet. With a low hazard potential, the dam has not been rated for condition assessment, but is regulated and inspected by the Montana Department of Natural Resources and Conservation (DNRC).
The dam's primary purpose for fire protection and water storage highlights its importance in maintaining water resources for various uses in the region. Despite the lack of recent condition assessment, the dam's low hazard potential suggests a low risk of failure, providing assurance to nearby residents and stakeholders. The dam's location in Yellowstone County, Montana, underlines its significance in managing water resources for both agricultural and emergency preparedness purposes.
Although details about the dam's maintenance and emergency preparedness measures are not provided in the data, its state-regulated status and inspection frequency indicate a level of oversight and management to ensure its continued functionality and safety. As an essential water management infrastructure in the area, Charter #1 plays a crucial role in supporting local water resource management efforts, contributing to the overall resilience and sustainability of the region's water supply in the face of changing climate conditions.

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.
