Summary
Built in 1975 by the USDA NRCS, this earth dam stands at a height of 30 feet and has a storage capacity of 53 acre-feet. With a low hazard potential and a condition assessment of 'Not Rated', Parsell serves its primary purpose of irrigation for the surrounding area. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and undergoes state inspections and enforcement to ensure its safety and compliance.
Situated in Congressional District 00 of Montana, Parsell is owned and maintained by a private entity. The dam has a spillway width of 35 feet and a maximum discharge capacity of 150 cubic feet per second. Despite not having a rated condition assessment, Parsell has not been modified since its completion in 1975 and does not have an Emergency Action Plan (EAP) in place. The structure is not operated by the US Army Corps of Engineers and does not have any associated federal agency funding or oversight.
Water resource and climate enthusiasts will be interested in the details of Parsell, a key irrigation infrastructure in the region. With its location in a rural area of Montana and its vital role in water management for agricultural purposes, Parsell stands as a testament to the importance of dams in sustaining water resources in a changing climate. The data presents a snapshot of the dam's specifications and regulatory status, shedding light on how private entities contribute to water resource management in the state.

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.
