Summary

The dam is situated on TR-SHOTGUN CREEK, with a height of 20 feet and a hydraulic height of 17 feet, serving the primary purpose of irrigation. With a storage capacity of 69 acre-feet, the dam covers a surface area of 5 acres and has a spillway width of 70 feet. While the dam is categorized as low hazard potential, its condition assessment is currently not rated, indicating a need for further evaluation and maintenance.

Owned by a private entity, Wilde falls under the jurisdiction of the Montana Department of Natural Resources Conservation (DNRC), with state-regulated permitting, inspection, and enforcement in place. The dam is located in BUFORD NORTH DAKOTA, with coordinates 48.1591° N, -104.159° E, in proximity to the Omaha District of the US Army Corps of Engineers. The structure has not been modified in recent years, and its emergency action plan (EAP) status, risk assessment, and management measures are yet to be updated or assessed.

Despite its age, Wilde continues to play a vital role in supporting agricultural activities in the region through its irrigation capabilities. With its low hazard potential and state-regulated oversight, the dam presents an opportunity for further assessment and potential upgrades to ensure its continued functionality and safety for the surrounding community and water resources.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
