Summary
Built in 1969 by USDA NRCS, this dam has a height of 20 feet and a length of 1980 feet, with a storage capacity of 201 acre-feet. Situated on TR-CAT CREEK, this structure is regulated by the DNRC and falls under the jurisdiction of the state of Montana for permitting, inspection, and enforcement.
Despite its low hazard potential, Manuel #2 has not been rated for condition assessment. The dam's emergency action plan status, risk assessment, and management measures are currently unknown, highlighting potential areas for improvement in terms of safety and preparedness. With the dam's proximity to the river and its purpose for fire protection and stock water, ensuring its structural integrity and emergency response readiness is crucial for water resource and climate enthusiasts in the area.
As a key component in the local water management infrastructure, Manuel #2 serves multiple purposes while also posing potential risks that need to be addressed. By evaluating its condition, updating emergency action plans, and implementing risk management measures, stakeholders can ensure the long-term sustainability and safety of this important water resource facility in Montana.

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.
