Summary

Completed in 1958, this dam stands at 13 feet tall and stretches 150 feet in length, with a storage capacity of 74 acre-feet. Despite its low hazard potential, its condition has not been rated, and it has not undergone recent inspections or maintenance assessments.

Managed by the Montana Department of Natural Resources and Conservation (DNRC), Christensen L&C #2 serves a primary purpose of "Other", with no specified structural or hydraulic height. It is situated in Big Horn County and falls under the regulatory jurisdiction of the state, with state permitting, inspection, and enforcement protocols in place. While the dam's emergency action plan status, risk assessment, and management measures remain unaddressed, its location and purpose make it an important asset for water resource management in the region.

For water resource and climate enthusiasts, Christensen L&C #2 presents an intriguing case study of a small but essential dam in the Montana landscape. Its history, design, and operational status offer valuable insights into the challenges and opportunities facing water infrastructure in the region. As discussions around climate change and water scarcity intensify, understanding the condition and management of dams like Christensen L&C #2 becomes increasingly crucial for ensuring the resilience and sustainability of water resources in Montana.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
