Summary
This dam on Mchessor Creek stands at 20 feet in height and spans 400 feet in length, providing a storage capacity of 72 acre-feet. It is regulated by the Montana Department of Natural Resources and Conservation (DNRC), with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
With a low hazard potential and a current condition assessment of "Not Rated," Mad Chant serves as a vital water resource for the Twin Bridges community. The dam's emergency action plan status and risk management measures are yet to be fully assessed, highlighting the need for ongoing monitoring and preparedness. Despite its modest size and function, Mad Chant underscores the importance of maintaining and safeguarding water infrastructure in the face of changing climate patterns and increasing water demands.
As water resource and climate enthusiasts continue to explore the interplay between water management and environmental sustainability, Mad Chant offers a case study in localized water storage and management practices. Its role in providing essential services like fire protection and supporting local ecosystems underscores the interconnectedness of water resources and community resilience. By understanding and supporting infrastructure like Mad Chant, enthusiasts can contribute to the broader conversation on water security and climate adaptation in a changing world.

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.
