Summary

Built in 1900 for irrigation purposes, this dam stands at a height of 10 feet and has a storage capacity of 59 acre-feet. While it has a low hazard potential and is not currently rated for its condition, it is regulated and inspected by the Montana Department of Natural Resources and Conservation.

Despite being over a century old, Bayer #1 continues to serve its primary purpose of irrigation in the area. With no associated structures and a relatively small storage capacity, this dam plays a vital role in managing water resources in Granite County. Enthusiasts of water resource management and climate change adaptation may find interest in the history and current condition of this dam, as well as the regulatory oversight it receives from the state.

As climate change continues to impact water availability and usage, understanding the state of infrastructure like Bayer #1 becomes increasingly important. By knowing the location, purpose, and condition of dams like this, water resource and climate enthusiasts can better assess the resilience of our water management systems and work towards sustainable solutions for the future.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
