Summary
Built in 1971 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock watering, and small fish pond support. With a height of 26 feet and a length of 100 feet, Lambing Shed has a storage capacity of 539 acre-feet and covers a drainage area of 10.94 square miles.
Despite its low hazard potential, Lambing Shed is regulated and inspected by the Montana Department of Natural Resources and Conservation (DNRC). The dam has not been rated for its current condition, and there is no available information on its last inspection date or emergency action plan status. It is crucial for water resource and climate enthusiasts to monitor the maintenance and safety of Lambing Shed to ensure its continued functionality and protection of downstream areas.
As an essential component of the local water infrastructure, Lambing Shed plays a vital role in water resource management and conservation efforts in Rosebud County, Montana. With its strategic location and multiple usage purposes, this dam serves as a valuable asset for the community while also posing low risks to surrounding areas. Continued monitoring and maintenance of Lambing Shed are necessary to ensure its long-term safety and efficiency in water resource management.

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.
