Summary
Lorang Grazing Assn dam, completed in 1952, serves as a vital structure along the TR Cheyenne river. Managed by a private entity, this earth dam stands at 16 feet in height and spans 680 feet in length, with a storage capacity of 96 acre-feet. While the dam is state-regulated and inspected, its hazard potential is considered low, and its condition is currently not rated.
Operated by the Natural Resources Conservation Service, the P. Lorang Grazing Assn dam plays a key role in water resource management and climate resilience efforts. Despite lacking a formal assessment of its condition, the dam continues to provide essential services for the surrounding area, including flood control and water storage. With its state-regulated status and regular inspections, the dam exemplifies the importance of proactive infrastructure maintenance for sustainable water resource management.
As climate change impacts continue to pose challenges for water resources, the P. Lorang Grazing Assn dam stands as a crucial asset for the community. With a focus on safety and compliance, the dam's low hazard potential and state-regulated status highlight the commitment to effective water management practices. As efforts to address climate change intensify, structures like the P. Lorang Grazing Assn dam will play a vital role in ensuring the resilience and sustainability 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.
