Summary
The dam has a height of 30 feet and a storage capacity of 67 acre-feet, with a low hazard potential and a condition assessment of "Not Rated." The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC), with state jurisdiction, permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.
Situated in Chouteau County, Toy Box is fed by diffused surface water and serves as an essential resource for the local area, providing water for firefighting, livestock, and recreational fishing. The dam's location in Congressional District 00, Montana, falls under the oversight of Representative Greg Gianforte (R), with no federal agency involvement in its ownership, funding, design, construction, or operation. Despite its age, Toy Box has not been rated for its current condition, highlighting the need for continued monitoring and maintenance to uphold its functionality and safety for the surrounding community.
With a storage capacity of 67 acre-feet and a normal storage level of 20 acre-feet, Toy Box plays a crucial role in water resource management in the region, supporting various uses while maintaining a low hazard potential. As a privately owned structure, the dam's compliance with state regulations and regular inspections by the DNRC ensure its stability and effectiveness in meeting the needs of Fort Benton and its residents. As water resource and climate enthusiasts, understanding the significance of Toy Box in sustaining local ecosystems and livelihoods underscores the importance of responsible dam management and monitoring for long-term sustainability and resilience in the face of changing environmental conditions.

Dam Data Reference
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.
