Summary
Built in 1954 by the USDA NRCS, this earth dam stands at 20 feet tall and spans 400 feet in length, providing a storage capacity of 62 acre-feet for irrigation purposes. Situated in Capitol, Montana, Rosecraze is regulated by the DNRC and undergoes state permitting, inspection, and enforcement to ensure its safety and functionality.
With a low hazard potential and a current condition assessment of "Not Rated," Rosecraze serves as a vital water resource for the surrounding area, with a drainage area of 2.5 square miles and a maximum discharge capacity of 1200 cubic feet per second. The dam's spillway width of 150 feet helps manage water flow during high-volume events, while its emergency action plan status and risk assessment remain undisclosed. Despite its age, Rosecraze continues to support agricultural activities in the region and remains an essential component of the local water infrastructure.
Managed by the Natural Resources Conservation Service, Rosecraze plays a crucial role in sustaining the agricultural community in Carter, Montana. As a key component of the irrigation system along Sevenmile Creek, this dam provides reliable water storage and distribution for farming operations in the area. With its historical significance and ongoing regulatory oversight, Rosecraze stands as a testament to the importance of water resource management and climate resilience 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.
