Summary
Completed in 1936, this Earth-type dam stands at 30 feet high and has a storage capacity of 325 acre-feet. With a low hazard potential and a hydraulic height of 28 feet, Wold serves as a vital water resource for the agricultural community in the region, providing irrigation water for crops and supporting local economies.
The dam is under the jurisdiction of the Montana Department of Natural Resources and Conservation (DNRC), which oversees its permitting, inspection, and enforcement activities. Despite being classified as "Not Rated" in terms of condition assessment, Wold is an essential infrastructure for water management in the area. The dam's maximum discharge capacity is 4290 cubic feet per second, ensuring effective flood control measures and water supply reliability for downstream users.
Wold plays a crucial role in water resource management in Montana, contributing to the sustainable use of water for agricultural purposes. With its strategic location in the Poplar area and its historical significance as a key irrigation structure, Wold continues to be a valuable asset for climate and water enthusiasts interested in understanding the intersection of water infrastructure, agriculture, and environmental stewardship in the region.

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.
