Summary
Completed in 1959, this earth dam serves multiple purposes, including fire protection, stock, and a small fish pond. With a height of 20 feet and a storage capacity of 156 acre-feet, it is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is subject to state jurisdiction, permitting, inspection, and enforcement.
Situated on TR-Cottonwood Creek, J B and R Haversland has a low hazard potential and has not been rated for its condition assessment. While it does not have a designated emergency action plan (EAP) in place, it meets state guidelines and is monitored by the DNRC. The dam's risk assessment, risk characterization summary, and risk management measures have not been specified in the available data. It is noteworthy that the dam does not fall under the jurisdiction of the US Army Corps of Engineers (USACE), indicating its private ownership and maintenance.
For water resource and climate enthusiasts, J B and R Haversland presents an interesting case study of a privately owned dam in Montana. Its multi-purpose functionality and state regulatory oversight highlight the importance of sustainable water management practices. The dam's location in a rural area and its low hazard potential underscore the need for ongoing monitoring and maintenance to ensure its safety and effectiveness in serving the surrounding community for fire protection, livestock, and recreational purposes.

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.
