Summary
Built in 1952, this earth dam stands at 26 feet in height and has a storage capacity of 150 acre-feet. With a primary purpose of irrigation, Blevins plays a vital role in providing water resources for agricultural activities in the area. Despite not being rated for its condition, the dam is considered to have a significant hazard potential.
Managed by the DNRC, Blevins is regulated, inspected, and enforced by the state of Montana to ensure its safety and functionality. The dam is situated in Blaine County and falls under the jurisdiction of Congressional District 00, represented by Greg Gianforte. While the dam has not been modified in recent years, it remains an important water management structure for the region, contributing to the overall water supply and agricultural productivity in the area.
Water resource and climate enthusiasts will find Blevins to be a fascinating example of how private dams like this one play a crucial role in sustaining agricultural activities in Montana. With its strategic location, storage capacity, and state regulation, Blevins showcases the intricate balance between water management and agricultural needs in the region. As efforts continue to ensure the safety and functionality of the dam, it serves as a reminder of the importance of sustainable water resource management in the face of changing climate patterns.

Dam Data Reference
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.
