Summary
The dam, completed in 1943, serves multiple purposes including fire protection, stock, and small fish pond management. With a height of 15 feet and a length of 650 feet, Beck has a storage capacity of 54 acre-feet, with a normal storage level of 28 acre-feet. The dam is classified as an earth dam and is under the regulatory jurisdiction of the Montana Department of Natural Resources and Conservation (DNRC).
Despite its low hazard potential, the condition of Beck dam has not been rated. However, the state agency responsible for regulation, inspection, and enforcement has confirmed that the dam is in compliance with state requirements. Beck has not undergone any modifications or updates in recent years, and information on emergency action plans, risk assessments, and management measures is currently unavailable. As a part of the Omaha District of the United States Army Corps of Engineers, Beck does not have any associated federal agency involvement in its ownership, funding, design, construction, or operations.
Water resource and climate enthusiasts interested in the Beck dam may find its history, purpose, and regulatory status intriguing. The dam's location in Roosevelt County, Montana, and its role in providing essential services like fire protection and stock management highlight its importance to the local community. With its relatively small storage capacity and low hazard potential, Beck serves as a reminder of the diverse array of water infrastructure projects that contribute to the sustainability and resilience of water resources in the region.

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.
