Summary

The dam, with an earth structure type, stands at a height of 12 feet and a length of 150 feet, providing a storage capacity of 76 acre-feet. Despite being classified as low hazard potential, Floodly is state regulated by the Department of Natural Resources and Conservation (DNRC) with permitting, inspection, and enforcement measures in place to ensure its safety and compliance.

Situated in Congressional District 00 of Montana, Floodly is overseen by private owners and falls under state jurisdiction for operation and maintenance. While the dam's condition is currently not rated and there is no recent inspection data available, the facility does not pose an immediate threat according to the Hazard Potential assessment. As an essential infrastructure for flood risk reduction in the area, Floodly serves as a crucial element in managing water resources and climate impacts in the region, contributing to the overall resilience and safety of the community.

With its strategic location and historical significance dating back to its construction in the 1940s, Floodly remains a key asset in the flood management infrastructure of Montana. While there are no specific details on modifications or upgrades over the years, the dam's operational status aligns with state regulations and guidelines. As water resource and climate enthusiasts continue to monitor and assess the impact of dams like Floodly on the local ecosystem and flood mitigation efforts, ongoing maintenance and oversight are essential to ensure the facility's continued effectiveness in safeguarding the surrounding areas from potential flood risks.

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.
