Summary
Built in 1954 by the USDA NRCS, this earth dam stands at 20 feet high and stretches 1000 feet in length, with a storage capacity of 135 acre-feet. It serves the primary purpose of irrigation and is regulated by the DNRC, with state permitting, inspection, and enforcement in place to ensure its safe operation.
Despite its low hazard potential and current "Not Rated" condition assessment, Saylor plays a crucial role in water resource management in the region. With a maximum discharge of 500 cubic feet per second and a spillway width of 100 feet, the dam provides essential water supply for agricultural activities in the area. The dam is located in Congressional District 00, Montana, under the representation of Greg Gianforte (R), and is part of the Omaha District of the USACE.
As a key infrastructure for water management in the region, Saylor represents the intersection of human ingenuity and environmental stewardship. Its presence underscores the importance of sustainable water resource practices in the face of climate change, ensuring the continued viability of irrigation systems for the agricultural community in Garfield County.

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.
